You multiply 32 by 2, since there are two hydrogens in every water molecule.

<span>We know that there are 2 moles of H in 1 mole of water. How many moles of H are there in 32 moles of water?
 
H2O ----------------- H
1 mol --------------- 2 mols
32 mol ------------- x
 
1 . X = 32. 2 ⇒ X = 64 mols of H

Answer:
</span>\boxed{\boxed{64\: mols\: of\: Hydrogen}}<span>

A certain mass of carbon reacts with 9.53 g of oxygen to form carbon monoxide. ________ grams of oxygen would react with that sa
yawa3891 [41]

Answer: 9.53 *2= 19.06

Explanation:

The law of multiple proportions states that if two elements combines to form more than one compound the ratio of masses of the second element which combines to the fixed mass of the first element will always be the ratios of the small whole numbers.

in case of carbon monoxide, mass of carbon will be the same of mass of oxygen.

But in case of carbon dioxide, if carbon is 9.53 units then oxygen will be twice as that of carbon.

CO2, so 9.53*2= 19.06 grams of oxygen will combine with 9.53 grams of carbon to form carbon dioxide.

n-Butane (C4H10) is burned with stoichiometric amount of oxygen. Determine the mole fraction of carbon dioxide and water in the
Fudgin [204]

Answer:

See details below

Explanation:

The balanced reaction equation is given below:

2C_{4} H_{10} + 13O_{2} → 8CO_{2} + 10H_{2} O

Mole fraction of CO2 to H20

= 8/10 = \frac{4}{5}

Mole ratio of C4H10 to CO2 is 2:8 = 1:4

1 mole of n-butane - 38.12 g

4 moles - ?

= 152.48g fuel consumed.

CARBOHYDRATES are found primarily in plant-based foods and are a major source of energy in the body (4 kcals per gram). If you c
SVETLANKA909090 [29]

Answer:

The 200 grams of carbohydrate would this convert to 800 kcals in a day.

Explanation:

Carbohydrates are the source of energy. The metabolism of 1 gram of carbohydrates gives 4 kcals of energy.

If 200 grams of carbohydrate is consumed in a day, then the energy provided by it is:-

Energy\ provided\ by\ the\ carbohydrate = 200\times 4\ kcals=800\ kcals

<u>The 200 grams of carbohydrate would this convert to 800 kcals in a day.</u>
