Can anyone help please ?

The mass remains constant

Explanation:

Burning a wood is a chemical change which produces many products. According to the law of conservation of mass, matter is neither created nor destroyed in a chemical reaction.

This implies that the quantity of the product and reactants will remain the same before and after the reaction. When we write a balanced reaction equation for this process, we find that the number of moles are conserved and the same. So, this is replicated in the mass of the combining species and the product they form. For such a combination, mass is the same.

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !

All the elements are arranged by melting points on the periodic table. in row they go from metals to gasses. in the row from sodium to argon, sodium is more reactive than the one on its right, magnesium.
