<span>ammonium sulphate give 2 moles of ammonium ions
so conc. of ammonium ions =2*0.100=0.200 </span>
From the stoichiometry of the reaction, we can see that the volume of carbon monoxide reacted is 44.8 L.
<h3>What is stoichiometry?</h3>
Stoichiometry is used to obtain the amount of substance reacted or the amount of product formed.
Number of moles of CO2 in 88g = 88g/4 g/mol = 2 moles
Molar mass of carbon monoxide = 12 + 16 = 28g/mol
We can see that 1 mole of oxygen was used in the reaction hence the mass of oxygen used is 32 g/mol. Given the stoichiometry of the reaction, 28g of carbon monoxide was burned.
If 1 mole of a gas occupies 22.4 L
2 moles of a gas occupies 2 moles * 22.4 L/1 mole
= 44.8 L

Explanation:
The car stopped due to a gravitational pull (gravity slowing it down) the energy is converted to kinetic energy and heat energy.
Answer:
Mass = 2.8 g
Explanation:
Given data:
Mass of HCl = 102 g
Mass of Zn = 128 g
Mass of H₂ = ?
Solution:
Chemical equation:
2HCl + Zn → H₂ + ZnCl₂
Number of moles of Zn:
Number of moles = mass/molar mass
Number of moles = 128 g/ 65.38 g/mol
Number of moles = 2 mol
Number of moles of HCl:
Number of moles = mass/molar mass
Number of moles = 102 g/ 36.5 g/mol
Number of moles = 2.8 mol
Now we will compare the moles of hydrogen gas with HCl and Zn.
HCl : H₂
2 : 1
2.8 : 1/2×2.8 = 1.4 mol
Zn : H₂
1 : 1
2 : 2
Number of moles of hydrogen formed by HCl are less thus it will limiting reactant.
Mass of Hydrogen:
Mass = number of moles × molar mass
Mass = 1.4 mol × 2 g/mol
Mass = 2.8 g
