hydrogen and helium and the most abundant elements in a nebula.
<span>The three methods are
wet gas desulfurisation(W)
dry gas desulfurisation(D)
seawater gas desulfurisation.(S)
In method W Calcium carbonate, CaCO3 material is used and material is obtained by quarrying. The solid waste is sold for use in buildings.
In method D Calcium oxide, CaO is used and the material is obtained by Thermal decomposition of calcium carbonate. Solid waste is sent to landfill.
In this method material is obtained from sea water. Liquid waste is returned to the sea.</span>
Answer:
2.288 Moles of NH₄NO₃
Explanation:
The Balance chemical equation is as follow:
(NH₄)₂CO₃ + 2 HNO₃ → 2 NH₄NO₃ + H₂O + CO₂
To solve this problem we will do following steps:
Finding moles of Ammonium Carbonate:
As we know,
Moles = Mass / M.Mass
So,
Moles = 110 g / 96.08 g/mol
Moles = 1.144 moles
Calculating moles of Ammonium Nitrate:
According to balance chemical equation;
1 mole of (NH₄)₂CO₃ produces = 2 moles of NH₄NO₃
So,
1.144 moles of (NH₄)₂CO₃ will produce = X moles of NH₄NO₃
Solving for X,
X = 2 moles × 1.144 moles ÷ 1 mole
X = 2.288 moles of NH₄NO₃
