Answer: Answer:
Explanation:
Apparent magnitude does not take into account the fact that not all stars are the same distance from Earth.

The balanced chemical equation :
NaHCO₃ + HCl → CO₂ + H₂O + NaCl
<h3>Further explanation</h3>
A balanced chemical reaction shows that the number of atoms of the reactant and the number of atoms of the product is the same
When baking soda (NaHCO3) reacts with hydrochloric acid (HCl), carbon dioxide bubbles (CO2) are created, along with water (H2O) and sodium chloride (NaCl) .
This statement shows that
Reactants (located to the left of the reaction)
Baking soda (NaHCO₃) and Hydrochloric acid (HCl)
product (located to the right of the reaction)
Carbon dioxide(CO₂),water (H₂O) and Sodium chloride (NaCl).
So the reaction :
NaHCO₃ + HCl → CO₂ + H₂O + NaCl
Acids are substances capable of donating hydrogen ion H⁺. On left h2po4- is acid, because that ion donate one hydogen ion to haso42-, and on the right h2aso4- is acid, because donate one H⁺ to hpo42- (when hpo42- accept one hydrogen ion, he transorms in h2po4-).
