What number of fe atoms and what amount (moles) of fe atoms are in 500.0 g of iron?

Answers

Answer 1

There are approximately 8.958 moles of iron atoms in 500.0 g of iron, and this corresponds to about [tex]5.393 \times 10^{24}[/tex] iron atoms.

How to determine how many moles of Fe atoms?

Calculate the moles using the formula:

[tex]\text{Moles} = \frac{\text{Mass}}{\text{Molar Mass}}[/tex]

Substitute the values:

Moles = [tex]\frac{500.0 \, \text{g}}{55.845 \, \text{g/mol}}[/tex]

Moles ≈ 8.958 mol

So, there are approximately 8.958 moles of iron atoms in 500.0 g of iron.

To find the number of iron atoms, use Avogadro's number, [tex]\(6.022 \times 10^{23}\)[/tex] atoms/mol:

Number of atoms = Moles * Avogadro's number

Number of atoms = [tex]8.958 \, \text{mol} \times (6.022 \times 10^{23} \, \text{atoms/mol})[/tex]

Number of atoms ≈ 5.393 [tex]\times 10^{24}[/tex]

Therefore, there are approximately 5.393 [tex]\times 10^{24}[/tex] iron atoms in 500.0 g of iron.

Describe the changes you think would take place if a capitalist system suddenly changes to a command system?

Answers

the government, rather than the free market, determines what goods should be produced, how much should be produced and the price at which the goods are offered for sale.

Several changes that would occur are:

- The type of goods and services that can be produced in the country would be determined by the government, not the market.

- There wouldn't be different price for a same product like in a capitalist system, since the product price would be set by the government as a national standard.

- Foreign investors would most likely turn away from countries with a command system since it provides very little rewards for products inventions.

Dimensional analysis: 1.35 kilometers per second = 3019.86 miles per hourFurther explanation

Dimensional analysis, also known as factor-label method or unit-factor method, is a method used to convert one unit to a different unit.

Dimensional Analysis is a very basic aspect of measurement and has many applications such as in applied physics.

There are seven steps to do dimensional analysis:

Identify the starting factor. Identify answer units. Determine conversion factors needed. Ensure the conversion factors are in the correct format. Cancel units that appear in both the numerator and denominator. Simplify the fractions. Solve.

1.35 kilometers per second= ? miles per hour

So first we identify the starting factor:

1.35 km/second * 0.621 miles/km = 0.838 miles/sec (the km cancel out)

Next, we need to convert from seconds into hours. There are 60 second in a minute and 60 minutes in an hour, so there are 60*60=3600 second/hour. Thus,

0.838 miles/second * 3600 second/hour = 3019.86 miles/hour.

Dimensional analysis 8.9x10^5 tons= ? Ounces

Answers

We know that there are 32,000 ounces in 1 ton. Therefore we use this conversion factor in our calculations. So to convert:

8.9 x 10^5 tons * (32,000 ounces / 1 ton) = 2.848 x 10^10 ounces

Writing in 2 significant figures:

2.85 x 10^10 ounces

Answer: 28.48x10^9 ounces.

Explanation:

We know that 1 ton = 32000 ounces.

Now, if we have 8.9x10^5 tons, how many ounces we have?

we know that each ton is equivalent to 32000 (or 3.2x10^4) ounces, so we need to multiply the number of tons by the number of ounces that each ton has:

8.9x10^5* 3.2x10^4 = (8.9*3.2)x(10^5*10^4) = (28.48)x10^(5+4) = 28.48x10^9

So 8.9x10^5 tons are equivalent to 28.48x10^9 ounces.

In what ways did native peoples transform North Americab environment before European colonization?

Answers

While the stamp of Native Americans on the landscape is certainly less than that of the Euro-American colonization, they certainly did leave their mark on the earth.

1. Homes - Whether a home was built as a permanent structure or with nomadic tendencies in mind, resources were put to use in their building. The oldest known permanent dwelling in North America is at Sky City, New Mexico. It was built by the Acoma tribe, which is now split into Acoma/Laguna.

2. Agriculture - Growing and harvesting plants requires fertile soil to be cultivated. This would require a certain amount of clearing land.

3. Trails - Nomadic tribes would have created trails they traveled at certain times of the year. Permanent homes would require travel routes whether for water, food or trade. These trails would not compare to the roads we know today, but there would be well traveled areas in abundance.

4. Tools- Native Americans used many types of tools. These tools might not have required a foundry to smelt metals, but none the less there are thousands of tool artifacts that have been found all over North America. With these tools, natives shaped the landscape around them.

What is continuous and categorical data?

Continuous data, like weight, height, or temperature, is frequently measured on a continuous scale and can have any value within a specified range. Contrarily, discrete values that belong to certain categories or groups such as gender, ethnicity, or product types make up categorical data. Continuous data is made up of values that fall anywhere in a given range of numbers. Examples of continuous data include temperature, time, and individual height. These are measurable values that can be found among a range of potential values.

Groups or categories are represented by categorical data, sometimes referred to as qualitative data. There isn't a numerical value attached to it. Examples of categorical data are car type, gender, and educational background.

Describe three reasons for the relatively high net primary productivity and high trophic efficiencies of natural grasslands

Answers

The natural grassland ecosystem is known for its relatively high net primary productivity and high trophic efficiencies compare to other types of ecosystem, many reasons are responsible for this and three of them are listed below:
1. Natural grassland are regionally adapted to survive environmental fluctuations and grazing pressure.
2. The diverse producer base of the natural grassland ecosystem results in a large number of trophic connections. This enhances energy transfer and reduces energy losses.
3. Nutrient cycling in the natural grassland ecosystem is very efficient and this contributes to the overall efficiency of the ecosystem. The recyclers in the ecosystem decompose dead organic matters and release the energy trapped inside them.

g= 1+2a/a , solve for a

Answers

Answer: a = 1/(g-2)

Explanation: We must solve the equation

g = 1 + 2a/a

if the equation is as written, then a/a cancels itself, because a/a = 1, and in that case we can not solve the equation for a:

g = 1 + 2a/a = 1 + 2 = 3

if the equation is, instead:

g = (1 + 2a)/a = 1/a + 2

we can solve it for a, wich means isolating a in one side of the equation, i will do it step by step.:

g = 1/a + 2

g - 2 = 1/a

a(g - 2) = 1

a = 1/(g-2)
