Answer: Bubbles formed would be evidence that a chemical reaction took place when the solutions were combined.
Explanation:
As it is given that both 
and HCl chemically combine together leading to the formation of NaCl, water and carbon dioxide gas. As the gas is forming and its formation will also form bubbles into the solution.
This formation of bubbles actually indicate that a chemical reaction has taken place. As molecules of a gas are held by Vander waal forces so, this gas will readily escape into the atmosphere.
Thus, we can conclude that bubbles formed would be evidence that a chemical reaction took place when the solutions were combined.

I really don’t know but
Phosphorus pentoxide is a white solid which does not have any distinct odour. The chemical formula of this compound is P4O10. However, it is named after its empirical formula, which is P2O5. The molar mass of phosphorus pentoxide corresponds to 283.9 g/mol.
Answer:
80.0 g Na and 20.0 g N2.
Explanation:
This means the limiting reactant determines the maximum mass of the product formed.
The name of this alkane is with central carbons are bonded to c h 3 is 2-methylbutane.

What is alkane?</h3>
Alkanes belong to the family of saturated hydrocarbons with carbon carbon single bond.
For the given alkane;
CH₃ H
CH₃ - C - C - CH₃
H H
Thus, the name of this alkane is with central carbons are bonded to c h 3 is 2-methylbutane.
