What information can you determine from the coefficients in this balanced chemical equation? mg + 2hcl → mgcl2 + h2

Answer : The information we can determine from the coefficients in this balanced chemical equation is, moles.

Explanation :

According to the law of conservation of mass, the number of individual atoms of an elements present on the reactant side must be equal to the the number of individual atoms of an elements present on the product side.

The given balanced reaction is,

From the balanced chemical reaction, we conclude that 1 mole of magnesium react with 2 moles of hydrochloric acid to give 1 mole of magnesium chloride and 1 mole of hydrogen.

Hence, the information we can determine from the coefficients in this balanced chemical equation is, moles.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
