Determine how many moles of hydrogen are needed to produce 50 grams of ammonia.

Chemistry
1 answer:
AlladinOne [14]3 years ago
3 0

Answer:

4.41 moles of hydrogen

Explanation:

N2 + 3H2 => 2NH3

No of mole = mass/molar mass

No of mole = 50/17 = 2.94

3 moles of H2 gives 2 moles of ammonia

X moles of H2 gives 2.94 moles of ammonia

X mole of H2 = 3 moles of H2 * 2.94 moles of ammonia/ 2 moles of H2

X = 4.41 moles of hydrogen

Given the chemical equation: 2 Pb + O2 → 2 PbO, if 51.8 grams of Pb are formed in this reaction, then 8.00 grams of O2 must have
Nutka1998 [239]

Answer:

If 51.8 of Pb is reacting, it will require 4.00 g of O2

If 51.8 g of PbO is formed, it will require 3.47 g of O2.

Explanation:

Equation of the reaction:

2 Pb + O2 → 2 PbO

From the equation of reaction, 2 moles of lead metal, Pb, reacts with 1 mole of oxygen gas, O2, to produce 2 moles of lead (ii) oxide, PbO

Molar mass of Pb = 207 g

Molar mass of O2 = 32 g

Molar mass of PbO = 207 + 32 = 239 g

Therefore 2 × 207 g of Pb reacts with 32 g of O2 to produce 2 × 239 g of PbO

= 414 g of Pb reacts with 32 g of O2 to produce 478 g of PbO

Therefore, formation of 51.8 g of PbO will require (32/478) × 51.8 of O2 = 3.47 g of O2.

If 51.8 of Pb is reacting, it will require (32/414) × 51.8 g of O2 = 4.00 g of O2
