Balance Chemical Equation is,
<span>CaO </span>₍s₎ <span>+ CO</span>₂ ₍g₎ <span>→ CaCO</span>₃ ₍s₎
According to Equation
56.07 g of CaO when reacted with excess CO₂ produces = 100.08 g of CaCO₃.
Then,
1.8 g of CaO is reacted with excess CO₂ = X g of CaCO₃ will produce.
Solving for X,
X = (100.08 g × 1.8 g) ÷ 56. 07 g
X = 3.21 g of CaCO₃
Answer:
is the value of the equilibrium constant for this reaction at 756 K.
Explanation:

Equilibrium concentration of 
![[COCl_2]=7.40\times 10^{-4} M](https://tex.z-dn.net/?f=%5BCOCl_2%5D%3D7.40%5Ctimes%2010%5E%7B-4%7D%20M)
Equilibrium concentration of 
![[CO]=3.76\times 10^{-2} M](https://tex.z-dn.net/?f=%5BCO%5D%3D3.76%5Ctimes%2010%5E%7B-2%7D%20M)
Equilibrium concentration of 
![[Cl_2]=1.78\times 10^{-4} M](https://tex.z-dn.net/?f=%5BCl_2%5D%3D1.78%5Ctimes%2010%5E%7B-4%7D%20M)
The expression of an equilibrium constant can be written as;
![K_c=\frac{[CO][Cl_2]}{[COCl_2]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BCO%5D%5BCl_2%5D%7D%7B%5BCOCl_2%5D%7D)


is the value of the equilibrium constant for this reaction at 756 K.
Answer:
D.
Double replacement, CaO + Cl2O
Explanation:
Answer:
10 moles of SO₂ are produced when 5 moles of FeS₂
Explanation:
Stoichiometry: it is the theoretical proportion in which the chemical species are combined in a chemical reaction. The stoichiometric equation of a chemical reaction relates molecules or number of moles of all the reagents and products that participate in the reaction.
In other words, stoichiometry establishes relationships between the molecules or elements that make up the reactants of a chemical equation with the products of said reaction. The relationships established are molar relationships (that is, moles) between the compounds or elements that make up the chemical equation.
The stoichiometric coefficients of a chemical reaction indicate the proportion in which said substances react.
Taking into account the above, you can apply the following rule of three: by stoichiometry if 4 moles of FeS₂ produce 8 moles of SO₂, then when reacting 5 moles of FeS₂ how many moles of SO₂ will they produce?

moles of SO₂= 10
<u><em>10 moles of SO₂ are produced when 5 moles of FeS₂</em></u>
