A 155 g -g sample of steam at 100°C is emitted from a volcano. It condenses, cools, and falls as snow at 0°C. (For water, 80. cal (334 J) is needed to melt 1 g of ice or must be removed to freeze 1 g of water and 540 cal (2260 J) is needed to convert 1 g of water to vapor at 100°C.) How many kilojoules of heat were released?

it should be all of them because it asks if you included all of those in your answer

explanation:

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
