The temperature of a 2 kg block increases by 5 degrees when 2000 J of thermal energy are added to the block. What is the specific heat of the block?

how to make a simple air condition

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).
