How would one convert 36 yd to centimeters (2.54 cm = 1 in)

ValentinkaMS [17]

I would go yards to feet, feet to inches, inches to centimeters. So 36 yards is 108 feet. There are 12 inches in a foot so 1,296 inches in 108 feet. Multiply that by 2.54 centimeters to get 3,291.84 centimeters in 36 yards.

How many grams of carbon disulfide will react with 2.14 moles of oxygen

MAXImum [283]

Reaction: CS₂ + 3 O₂ → CO₂ + 2 SO₂

For every mole of CS₂, 3 moles of Oxygen formed.
So, Number of moles of CS₂ = 2.14/3 = 0.713 mol

Now, Number of moles = Given mass / Molar mass
Mass = Molar mass * Number of moles
Mass = 76 * 0.713 [ Molar mass of CS₂ = 76 g/mol ]
Mass = 54.21 g

In short, Your Final Answer would be: 54.21 Grams

Hope this helps!

3)<br> How many atoms are in 14 moles of cadmium?

andre [41]

Answer:

$8.4322\times10^{24} atoms$ atoms are in 14 moles of cadmium.

Explanation:

Cadmium is a white and silvery metal that is found in the curst of the earth.During the production process of metals such as lead, copper, zinc, cadmium is extracted

Cadmium is present in some foods and is emitted when fossil fuels like as coal and oil is used, smoking cigarettes. It is used in craft glazes, metal batteries, and coatings.

We know that 1 mole of Cadmium (Cd contains) 6.023*1023 atoms, which is Avogadro's number.

So in 14 Grams of Cadmium, the number of atoms present is,

=>14×number atoms present in one cadmium atom

=> $14\times 6.023\times10^{23}$

=> $8.4322\times10^{24} atoms$

Help please! What is the mass of the iron (Fe) involved in this reaction? Identify the following equations as balanced or unbala

eimsori [14]

<h2>Question 1:</h2><h3>32g + <u><em>56g</em></u> --> 88g</h3>

This one's just a simple math problem. Do 88 - 32, which is 56. You can also find the same answer by looking for the atomic mass of iron (Fe), which rounds up to 56.

<h2>Question 2:</h2><h3>This equation is <u><em>balanced</em></u>.</h3>

On the left side, there is 2 Nitrogen (because of the subscript), and 6 Hydrogen (3 x 2 = 6). On the right side, there is 2 Nitrogen (because of the coefficient), and 6 Hydrogen. (2 x 3 again) There are 2 Nitrogen and 6 Hydrogen on each side, therefore the equation is balanced.

<h2>Question 3:</h2><h3>This equation is <em><u>unbalanced.</u></em></h3>

On the left side, there are 2 Nitrogen (N) and 2 Hydrogen (H). On the right side, there is 1 Nitrogen and 6 Hydrogen. There are 2 Nitrogen and 2 Hydrogen on one side, while the other only has 1 Nitrogen and 6 Hydrogen. Therefore the equation is unbalanced.

<h2>Question 4:</h2><h3>This equation is <em><u>balanced.</u></em></h3>

On the left side, there are 2 Chromium (Cr) and 6 Chlorine (Cl). On the right side, there are 2 Chromium and 6 Chlorine. There are 2 Chromium and 6 Chlorine on each side, therefore the equation in balanced.
