How much energy is required to melt a 500. gram block of iron? The heat of vaporization is 6090 J/g and the heat of fusion is 24
galben [10]

The mass of iron block is 500 g. The amount of energy required to melt the iron block needs to be calculated. Melting means conversion of solid to liquid thus, heat of fusion is used which is 247 J/g.

From heat of fusion, 247 J of energy is released by melting 1 g of iron block. Thus, the amount of heat released by melting 500 g of iron rod will be:

H= 247 J/g× 500 g=1.23×10^{5}

Hence, option B is correct.

Which equation represents a neutralization reaction?
Fittoniya [83]

Answer:

H2SO4(aq) + Mg(OH)2(aq) -> MgSO4(aq) + 2H2O(l)

Explanation:

A neutralization reaction is a chemical reaction in which the acid, (aqeous H2SO4) reacts completely with an appropriate amount of base, (aqueous Mg(OH)2) to produce salt, (aqueous MgSO4) and water, (liquid 2H2O) only.

H2SO4(aq) + Mg(OH)2(aq) -> MgSO4(aq) + 2H2O(l)

Acid + base → Salt + Water.

During this reaction, the hydrogen ion, H+, from the H2SO4 is neutralized by the hydroxide ion, OH-, from the Mg(OH)2 to form the water molecule, H2O.

Thus, the formation of salt, MgSO4(aq) and water, 2H2O(l) makes it a neutralization reaction.
