Does the chemical reaction presented in the data table follow the law of conservation of matter? Justify your answer with evidence from the
document.

No, it does not follow

Explanation:

The law of consevation of matter states that matter can neither be created nor destroyed. Hence, in a closed system involving a physical or chemical reaction, the amount of matter (mass) present in the reactants must equate the amount of matter in the products.

i.e. mass of reactants = mass of products

In the chemical reaction in the image, sodium reacts with hydrogen chloride (reactants) to give sodium chloride and hydrogen gas (products). That is,

Na(s) + HCl(aq) > NaCl(aq) + H2(g)

According to the image, the mass of Na= 14.25g, HCl= 9.50g, {NaCl + H2} = 22.98g

The mass of the reactants is 14.25+9.50= 23.75g

Mass of products= 22.98g

The mass of reactants and products are not equal and hence, does not follow the law of conservation of matter.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
