Balance the 2 chemical equation below: 1) _____H2 + _____02 ---> _____H20 2) _____CH4 + _____Cl2 ---> _____CCl4 + _____HCl
sergij07 [2.7K]

Answer:

1.)    2H2  +  O2  --->  2H2O

2.)   CH4  +  4Cl2 --->  CCl4  +  4HCl

Explanation:

In order to balance the equation, you have to make sure there are the same amount of each element on both sides.

Ex (#1).  By adding the coefficients infront of H2 and H20, You now have 4 hydrogen's and 2 oxygens on the left side as well as 4 hydrogens and 2 oxygens on the right side.

Sorry if that's confusing, but hope this helps! :)

__ CaSO4 + ____AIP --> ____Ca3P2 + ____AI2(SO4)3
4vir4ik [10]

Answer:

4.89 mol

Explanation:

Step 1: Write the balanced equation

This is a double displacement reaction.

3 CaSO₄ + 2 AIP ⇒ Ca₃P₂ + AI₂(SO₄)₃

Step 2: Establish the appropriate molar ratio

According to the balanced equation, the molar ratio of CaSO₄ to AlP is 3:2.

Step 3: Calculate the moles of AlP needed to react with 7.33 moles of CaSO₄

We will use the previously established molar ratio.

7.33 mol CaSO₄ × 2 mol AlP/3 mol CaSO₄ = 4.89 mol AlP
