Answer is: 3,2 · 10¹¹ t of quicklime.Â
Chemical reaction: COâ‚‚ + CaO → CaCOâ‚.
m(CO₂) = 2184,82·10¹² · 115 = 2,51 · 10¹ⷠg.
n(COâ‚‚) = m(COâ‚‚)Â Ă· M(COâ‚‚)
n(CO₂) = 2,51 · 10¹ⷠg ÷ 44 g/mol = 5,7 · 10¹ⵠmol.
from reaction n(COâ‚‚) : n(CaO) = 1 : 1.
n(CaO) = 5,7· 10¹ⵠmol.
m(CaO) = 5,7· 10¹ⵠmol · 56 g/mol = 3,2 · 10¹ⷠg = 3,2 ·
10¹¹ t.
n - amount of substance
Answer:
1
Explanation:
your can only test one thing at a time
Explanation:
Orbitals = (Shell number)² = 3² = 9.
Answer: Combustion
Explanation:
Methane gas or natural gas is the hydrocarbon that reacts with oxygen as shown below: CH4 + 2O2 → CO2 + 2H2O There are two types of combustion reactions: complete and incomplete combustion. Therefore there are four products, carbon dioxide, water, carbon, and carbon monoxide.
