How much heat is absorbed when 4.5g of ice at 0°C melts to water at 10°C?

90.45 joules

Explanation:

The quantity of Heat Energy (Q) absorbed by ice depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

Thus, Q = MCΦ

In this case,

Q = ?

Mass of ice = 4.5g

C = 2.010 J/g°C (Though not provided, but the specific heat capacity of ice is 2.010 J/g°C)

Φ = (Final temperature - Initial temperature)

= 10°C - 0°C = 10°C

Then, Q = MCΦ

Q = 4.5g x 2.010 J/g°C x 10°C

Q = 90.45 joules

Thus, 90.45 joules of heat is absorbed by ice.

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
