Question

Ba₊O⇒? AgJ⇒?⁺J₂? CU O+H2⇒?+H²O

Answer 1

2Ba + O2 = 2BaO 
2AgJ = 2Ag + J2
CuO + H2 = Cu + H2O

Answer 2

Let's break down each of the chemical equations you provided:

1. Ba + O -> ? This equation is incomplete because it does not specify the reactants or products clearly. However, assuming you meant to write "Ba + O2," the balanced equation for the reaction between barium (Ba) and oxygen (O2) would be: 2 Ba + O2 -> 2 BaO This reaction represents the formation of barium oxide (BaO).

2. Ag + J -> ? Again, this equation is incomplete because it does not specify the reactants or products clearly. Assuming you meant to write "Ag + I2," the balanced equation for the reaction between silver (Ag) and iodine (I2) would be: 2 Ag + I2 -> 2 AgI This reaction represents the formation of silver iodide (AgI).

3. ? + J2 -> ? The equation is incomplete as it lacks clear reactants and products. Please provide the specific substances involved for a balanced equation.

4. Cu + O2 + H2 -> ? To balance this equation, we need to consider the reaction between copper (Cu), oxygen (O2), and hydrogen (H2). The balanced equation is: 2 Cu + O2 + 2 H2 -> 2 CuO + 2 H2O This reaction represents the formation of copper(II) oxide (CuO) and water (H2O) when copper reacts with oxygen and hydrogen.

Please provide additional details if you have specific substances in mind for the third equation.
