Gallium metal is heated in oxygen gas, it melts and forms solid gallium(III) oxide.

Ga + O₂⇒ Ga O₂

Balance the atoms with simple - whole coefficients.

4 Ga + 3 O₂ 2 Ga₂O₃.

Specify the states of matter.

4 Ga(s) + 3 O₂ (g) ⇒ 2 Ga₂O₃.(s)

Therefore, balanced equation is----- 4 Ga(s) + 3 O₂ (g) ⇒ 2 Ga₂O₃.(s)

What is the balanced formula equation?

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.

Why are equations balanced?

A balanced equation obeys the Law of Conservation of Mass. This is an important guiding principal in science. Finally, a balanced equation lets up predict the amount of reactants needed and the amount of products formed.

A jar is filled with water, and the lid is closed tightly. The jar is kept at constant temperature. What happens at the surface

Katarina [22]

<h2>Hello!</h2>

The correct answer is A: Water molecules evaporate and condense at the same rate.

Evaporation is defined as the physical change from liquid to gas, and Condensation is the physical change from gas to liquid.

At any given temperature, these two processes occur at once, in a dynamic equilibrium.

When the lid is closed, evaporation occurs faster than condensation, and pressure increases. Then, when pressure reaches a critical value, condensation starts to occur faster than evaporation, until an equilibrium is reached, and the pressure of the water molecules in the gas phase is maximum for that temperature. The pressure at that point is called Vapor Pressure.

Have a nice day!

A balloon is filled to a volume of 1.50 L with 3.00 moles of gas at 25 °C. With pressure and temperature held constant, what wil

Vaselesa [24]

Answer: 1.6L

Explanation:

V1 = 1.50 L,

V2 =?

n1 = 3mol

n2 = 3 + 0.2 = 3.2mol

From PV = nRT

V1 /n1 = V2/n2

1.5/3 = V2 /3.2

V2 = (1.5/3/) x 3.2 = 1.6L
