To burn 1 molecule of c7h16 to form co2 and h2o (complete combustion), how many molecules of o2 are required?
Eleven molecules of O2 are required to completely combust one molecule of C7H16, producing CO2 and H2O. The balanced chemical reaction of this process is: C7H16 + 11O2 → 7CO2 + 8H2O.
Explanation:Combustion of one molecule of C7H16 (heptane) to produce CO2 (carbon dioxide) and H2O (water) requires 11 molecules of O2 (oxygen). The balanced chemical equation of this reaction is:
C7H16 + 11O2 → 7CO2 + 8H2O
The equation shows that for every one molecule (or mole) of C7H16, 11 molecules (or 11 moles) of oxygen are needed. An analogy can be seen in the combustion of methane where one methane molecule and two oxygen molecules react to yield one carbon dioxide molecule and two water molecules.

Name the set(s) of numbers to which 1.18 belongs.
a. rational numbers
b. rational numbers, irrational numbers
c. natural numbers, whole numbers, integers, rational numbers
Answer:
a. rational numbers
Step-by-step explanation:
The number is between integers, so it can't be an integer or a whole number.
In general, 1.18 belongs to three sets of numbers.
Firstly, it is a rational number because it can be written in the form p/q where p and q are integers and q is not equal to zero.
1.18=[tex]\frac{118}{100}[/tex]
Secondly, all rational numbers are also real numbers and all real numbers are complex numbers.
But we have been given to choose from only rational numbers, irrational numbers, natural numbers or whole numbers.
So, the only answer is rational number.

The prefix milli- means one thousandth, or 10–3. how many milliseconds (ms) are in 6.7 seconds? 6.7 × 10–3 ms 2.0 × 104 ms 6.7 × 102 ms 6.7 × 103 ms
You know that the prefix mili means one thousandth or 1/100.
Numerically speaking, one thousandth is equals to 10 to the power of negative 3.
Solving seconds to milliseconds:
6.7 seconds x 1000 milliseconds / 1 second
Cancelling out the unit seconds. Then multiplying 6.7 to 1000 milliseconds.
The answer is 6,700 milliseconds or 6.7 x 10^3 ms
If -4 is added to a number and them sum is doubled, the result is -16 less than the number. find the number.
Final answer:
By setting up an equation based on the given problem (2(n - 4) = n - 16) and solving for n, we find that the number in question is – 8.
Explanation:
To find the number in question, let's represent the unknown number as n. According to the problem, if -4 is added to a number and then the sum is doubled, it equals the number decreased by 16. So the equation based on the problem is:
2(n - 4) = n - 16
Expand the left side of the equation:
2n - 8 = n - 16
Now we want to get all the n terms on one side and the constants on the other. To do this, we subtract n from both sides:
n - 8 = -16
Next, we add 8 to both sides to solve for n:
n = -16 + 8
n = -8
So the number in question is -8.
The Greenville Art Museum had 12 sculptures on display that were made by students. The museum received 3 more student sculptures. After two weeks they loaned 4 of the sculptures to another museum. How many student sculptures are at the Greenville Art Museum now?
The Greenville Art Museum currently has 11 sculptures on display after receiving 3 more sculptures and then loaning out 4 sculptures.
Explanation:The Greenville Art Museum initially had 12 sculptures on display. They added 3 more sculptures to their collection, which increased the total number of sculptures to 15. Afterwards, they loaned out 4 sculptures to another museum. To find out how many sculptures are still at the Greenville Art Museum, we subtract the number of sculptures loaned out from the total.
Starting with 15 sculptures, after loaning out 4, we do the following calculation:
15 - 4 = 11 sculptures
Therefore, the Greenville Art Museum now has 11 sculptures on display.

At green deli employees earn double time for any hours worked in addition to their usual 40-hour week. Ester Klein worked 43 hours this week. Klein's regular hourly rate is $9.00 an hour. What is her total pay this week?
Answer:
$414.00
Step-by-step explanation:
At green deli employees earn double time for their over time.
Klein's regular hourly rate = $9.00
So, her overtime rate = $9 × 2 = $18.00
Ester Klein worked 43 hours this week.
40 hours regular work + 3 hours overtime
Her total pay this week = (40 × 9) + (3 × 18)
= 360 + 54
= $414.00
Her total pay this week is $414.00

Find the equation of the line perpendicular to x−5y=15 that passes through the point (−2,5).
1. Solve the given equation for y.
x - 5y = 15
-5y = -x + 15
y = (-x + 15)/-5
y = (x/5) - 3
y = (1/5)(x) - 3
The slope is 1/5. See it?
The equation we are looking for has a slope which is the negative inverse of the slope in the equation we just solved for y.
The slope for the equation we want is -5 which is the negative inverse of 1/5. Undetstand?
We have the slope of the new equation and one point is given.
Plot BOTH into the point-slope formula and solve for y. To solve for a variable means to isolate the variable ALONE on one side of the equation.
y - y_1 = m(x - x_1)...This is the point-slope formula. Our given point is (5,-2)
y - 5 = -5(x - (-2))
y - 5 = -5(x + 2)
We now solve for y and that's it.
y - 5 = -5x - 10
y = -5x - 10 + 5
The equation we want is y = -5x - 5.

A peer is having difficulty finding angle measures using trigonometric ratios in a right triangle. Create an example to demonstrate how to do this and be sure to address using the reciprocal relationships (cosecant, secant, cotangent too)
Final answer:
To find angle measures using trigonometric ratios, such as sine, cosine, and tangent, as well as their reciprocals (cosecant, secant, and cotangent), use SOHCAHTOA to relate the sides of the triangle to the angle. Utilize the inverse trigonometric functions (like arccos) on your calculator to find the angle's measure from the ratio you have calculated with sides of the triangle.
Explanation:
To find angle measures using trigonometric ratios in a right triangle, we can use the mnemonic SOHCAHTOA, which stands for Sine equals Opposite over Hypotenuse, Cosine equals Adjacent over Hypotenuse, and Tangent equals Opposite over Adjacent. Let's create an example:
Suppose we have a right triangle with a hypotenuse (h) of 10 units and an adjacent side (x) to angle theta of 8 units.
To find the cosine of angle theta, we use the ratio Cos(theta) = x/h. Thus, Cos(theta) = 8/10 = 0.8.
To determine the actual measure of angle theta, we use the inverse cosine function: theta = arccos(0.8), which gives us the angle's measure in degrees or radians.
For the reciprocal, secant (Sec) is simply the inverse of cosine: Sec(theta) = 1/Cos(theta) = 10/8 = 1.25.
If we needed to use the cotangent, which is the reciprocal of the tangent, we would first need to find the opposite side (y) using the Pythagorean theorem and then use the ratio Cot(theta) = x/y.
It's essential to understand these relationships and how to use the inverse functions to find the angle measures in a right triangle. Reciprocal relationships involve the use of cosecant (Csc), which is 1/Sin(theta), secant (Sec), and cotangent (Cot), which is 1/Tan(theta). Always make sure your calculator is set to the correct unit (degrees or radians) before calculating the angle.
