Kazeer [188]

Answer:

Bubbles will be formed when two solutions will be combined.

Explanation:

When the solution containing Na_{2}CO_{3} and HCl as a solute will be combined, the reaction will be as follows,

Na_{2}CO_{3}(aq) + 2HCl(aq) \rightarrow   2NaCl(aq)+ H_{2}O(l)+CO_{2}(g)

As a result of combination of the two solutions bubbles will be formed which will depict the evolution of carbon dioxide gas.

Your old bike left out in the rain starts to rust. What coefficients fill in the blanks to balance the equation?
galina1969 [7]
Hello!

The balanced chemical equation for the rusting of iron is the following:

4 Fe + 3 O₂ → 2Fe₂O₃

The coefficients to balance the equation are 4,3,2. The fundament of this balance is the Law of Conservation of Mass. This Law states that matter is neither created nor destroyed in a chemical reaction, and in a chemical equation, the moles of each atom is conserved in both sides of the arrow. That means that if 4 Fe atoms are on the left side, 4 Fe atoms should be on the right side. 

A suggestion for balancing equations is to start with metal atoms, continuing with non-metals, then hydrogen and lastly oxygen. 

Have a nice day!
