Convert the following into balanced equations:
sesenic [268]

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.

the half of an oxidation-reduction reaction shows the iron gains. what does this electron gain mean for iron.
Nataly [62]

The correct answer is option C, that is, it is reduced.

In reduction and oxidation reactions, reduction refers to the loss of an oxygen atom from a molecule or the gaining of one or more electrons. A reduction reaction is observed from the perspective of the molecule being reduced, as when one molecule gets reduced, another one gets oxidized. The complete reaction is called a redox reaction.

In the given case, iron gains electrons mean that it is reduced.

Process by which plants, algae, and many types of bacteria use sunlight, water, and carbon dioxide to make food and oxygen
Katena32 [7]

Answer: Photosynthesis

Explanation:

<em>The process of photosynthesis</em> is used to help make food for plants. The inputs are sunlight, water (H2O), and carbon dioxide (CO2). Then the outputs are glucose (C6H12O6) which is food, and oxygen (O2) is released.

I hope this helps :)
