pOH =-log[OH⁻]
pOH =-log(1.0 × 10⁻⁹)
pOH = 9.00
Step 2. Calculate the pH
pH + pOH = 14.00
pH + 9.00 = 14.00
[tex]\boxed{\textbf{pH = 5.00}}[/tex]
Final answer:
The pH of a solution with a hydroxide ion concentration of 1.0 × 10⁻⁹ M is 5, indicating the solution is acidic.
Explanation:
To calculate the pH of a solution with a known hydroxide ion concentration, we can use the relationship between the concentration of hydroxide ions ([OH-]) and hydrogen ions ([H+]), which is given by the ionic product of water (Kw = 1.0 × 10⁻¹⁴ at 25°C). The pH is defined as the negative logarithm of the hydrogen ion concentration, pH = -log([H+]).
Since we have the hydroxide ion concentration ([OH-] = 1.0 × 10⁻⁹ M) we can find the hydrogen ion concentration from Kw:
Kw = [H+] × [OH-]
[H+] = Kw / [OH-]
[H+] = (1.0 × 10⁻¹⁴ M2) / (1.0 × 10⁻⁹ M)
[H+] = 1.0 × 10-5 M
Now we can calculate the pH:
pH = -log([H+])
pH = -log(1.0 × 10⁻⁵)
pH = 5
A pH of 5 indicates that the solution is acidic, as a pH less than 7 is characteristic of an acidic solution.
When looking at the endoplasmic reticulum of a cell, the microscope zooms in enough to see ribosomes that are embedded in the outside of the endoplasmic reticulum. Which type of endoplasmic reticulum is this?
A. Solid
B. Smooth
C. Rough
D. Bumpy
Answer:
Rough.
Explanation:
The presence of ribosome on enfoplasmic cisterna make it rough.. Called RER
Answer:
C. Rough
Explanation:
When ribosomes are attached to the outer surface of an endoplasmic reticulum it is called rough endoplasmic reticulum. When ribosomes are not attached to the outer surface of an endoplasmic reticulum it is called smooth endoplasmic reticulum. Protein translation takes place at the rough endoplasmic reticulum whereas lipids and hormones are synthesized at the smooth endoplasmic reticulum.
In two or more complete sentences explain how to balance the chemical equation and classify its reaction type. ___P4 + ___O2 ⟶ ___P2O3
According to the conversation of mass, mass cannot be created or destroyed. This means whatever is done to one side, must be done to the other.
There are 4 Phosphorus atoms on the left, there must be 4 on the right. To do this, you must multiply the P2O3 by 2 to get 4 Phosphorus atoms and 6 Oxygen atoms. Now to balance the Oxygen atoms, you must multiply the oxygen atoms on the left by 3.
1 P4 + 3 O2 —-> 2 P2O3
Lastly, this equation type is synthesis (combination) because two reactants are becoming a single product.
To balance the chemical equation P4 + O2 -> P2O3, you need to place a coefficient of 5 in front of O2, resulting in the balanced equation P4 + 5O2 -> 2P2O3. This equation represents a synthesis reaction.
Explanation:A balanced chemical equation is one that has the same number of atoms for each element on both sides of the equation. To balance the given equation, you need to determine the appropriate coefficients for the reactants and products.
In this case, you would balance the equation P4 + O2 → P2O3 by placing a coefficient of 5 in front of O2, resulting in the balanced equation P4 + 5O2 → 2P2O3. This equation represents a synthesis reaction, where two or more substances combine to form a new compound.

A nuclear power plant operating for 60 years typically generates between 1200 to 1800 tons of high-level nuclear waste. This waste is highly radioactive and needs to be stored safely to avoid environmental contamination. Despite this, nuclear power plants help reduce carbon emissions compared to fossil fuel-powered plants.
Explanation:The amount of nuclear waste produced by a power plant operating for 60 years depends on several variables, such as the type of reactor and the fuel it uses. However, in general terms, a typical nuclear reactor generates about 20 to 30 tons of high-level nuclear waste annually. Over 60 years, this accumulates to 1200 to 1800 tons of high-level waste.
High-level waste includes elements like uranium-235, which result from the fission process in the reactor. This waste is highly radioactive and requires proper management and disposal methods. Long-term storage solutions often include secure facilities such as old salt mines or inside of stable mountains to prevent environmental contamination.
It's essential to mention that while nuclear power plants produce this level of harmful waste, they also help to mitigate climate change by reducing carbon emissions. Compared to coal-fired power plants, which can produce 370,000 metric tons of CO2 every day, nuclear power plants do not emit greenhouse gases during operation.

If you have 100 grams of a radioactive isotope with a half life of 10 years how much of the isotope will you have left after 10 years
Answer:
50.0 g.
Explanation:
It is known that the decay of a radioactive isotope isotope obeys first order kinetics. Also, it is clear that in first order decay the half-life time is independent of the initial concentration.Half-life time is the time needed for the reactants to be in its half concentration.If reactant has initial concentration [A₀], after half-life time its concentration will be ([A₀]/2).So, the mentioned radioactive isotope after 10 years will have (100/2 = 50.0 g).Thus, the amount of radioactive isotope is 50.0 g.
We want to find how much of a radioactive isotope we will have after a given time, given that we know the half life of the isotope.
After 10 years, there will be 50 grams of the isotope.
The half life of a given quantity is defined as the time such that the quantity is reduced ot its half.
So if we initially have a quantity A with a half time T, after the time T our quantity will be A/2.
Now we have 100 g of a radioactive isotope with a half life of 10 years. Then after that time, 10 years, we will have half that mass of isotopes.
This is 100g/2 = 50g
After 10 years we will have 50 grams of isotopes.

How do a strong acid and a weak acid behave differently when each is dissolved in water?
A strong acid fully dissociates into its constituent ions when dissolved in water, making its solution highly acidic. Conversely, a weak acid only partially dissociates and the resulting solution is less acidic. The distinction between strong and weak acids is about the level of ionization in water.
Explanation:A strong acid like hydrochloric acid (HCl) behaves differently than a weak acid such as acetic acid when each is dissolved in water. Upon dissolution in water, strong acids like HCl fully dissociate into their constituent ions, in this case hydrogen (H+) and chloride (Cl-) ions. This complete dissociation contributes to the highly acidic nature of such solutions.
Conversely, weak acids do not fully dissociate when dissolved in water. For example, acetic acid, found in vinegar, only partially dissociates, leaving a significant proportion of the dissolved molecules in their original form. This generates a smaller concentration of hydrogen ions (H+), making the solution less acidic than that formed by a strong acid.
It's important to note that the difference between strong and weak acids lies in the extent of their ionization in water, not in their inherent acidity. A weak acid can have a very low pH if its concentration is high enough.

What is the overall enthalpy of reaction for the equation shown below?
Round the answer to the nearest whole number.
P4O6(s) + 2O2(g) --> P4O10(s)
Answer:
- 1300 kJ.
Explanation:
We should modify the given two reactions to reach to the final reaction:We should reverse the first reaction and so multiply its ΔH by (- 1):
P₄O₆(s) → P₄(s) + 3O₂(g), ΔH₁' = 1640.1 kJ.
The second reaction also should be reversed and so multiply its ΔH by (- 1):
P₄(s) + 5O₂(g) → P₄O₁₀(s), ΔH₂' = - 2940.1 kJ.
If we add the two reactions after modification, we get:

Explanation:
Final answer:
A moon orbits a planet, and a planet orbits the Sun, completing the analogy and indicating 'Sun' is the correct answer to fill in the blank.
Explanation:
The question requires drawing an analogy between celestial bodies based on their relationships within the solar system. A moon orbits a planet, and similarly, a planet orbits something else. The best answer to what a planet orbits is the Sun, which is at the center of our solar system.
We know that all the planets in our solar system, including Earth, revolve around the Sun. This is due to the Sun's gravitational pull, which keeps the planets in their respective orbits. Likewise, moons, including Earth’s moon, orbit their respective planets due to the gravitational pull of these planets.
Therefore, the analogy completes as follows: Moon is to planet as planet is to Sun. The correct choice is B. Sun.

If the actual yield of a reaction is 37.6 g while the theoretical yield is 112.8 g what is the percent yield
The answer is:
The percent yield of the reaction is 32.45%
Why?To calculate the percent yield, we have to consider the theoretical yield and the actual yield. The theoretical yield as its name says is the yield expected, however, many times the difference between the theoretical yield and the actual yield is notorious.
We are given that:
[tex]ActualYield=37.6g\\TheoreticalYield=112.8g[/tex]
Now, to calculate the percent yield, we need to divide the actual yield by the theoretical and multiply it by 100.
So, calculating we have:
[tex]PercentYield=\frac{ActualYield}{TheoreticalYield}*100\\\\PercentYield=\frac{37.6g}{112.8g}*100=0.3245*100=32.45(percent)[/tex]
Hence, we have that the percent yield of the reaction is 32.45%.

B) 5,200 years
C) 10,500 years
D) 15,600 years
the correct answer is C
Answer:
C) 10,500 years.
Explanation:
The decay of cobalt-60 is a first order reaction.The rate constant of the reaction (k) in a first order reaction = ln (2)/half-life = 0.693/(5272 year) = 1.314 x 10⁻⁴ year⁻¹.The integration law of a first order reaction is:
kt = ln [A₀]/[A]
k is the rate constant = 1.314 x 10⁻⁴ year⁻¹.
t is the time = ??? years.
[A₀] is the initial percentage of cobalt-60 = 25.0 g.
[A] is the remaining percentage of cobalt-60 = 6.25 g.
∵ kt = ln [Ao]/[A]
∴ (1.314 x 10⁻⁴ year⁻¹)(t) = ln (25.0 g)/(6.25 g)
(1.314 x 10⁻⁴ year⁻¹)(t) = 1.386.
∴ t = 1.386/(1.314 x 10⁻⁴ year⁻¹) = 10,550 years ≅ 10,500 years.
