In 1 kilogram of pure water, the mass of hydrogen atoms is approximately 112 grams, or 0.112 kilograms. what is the energy equivalent of this mass in joules?

Using Einstein’s famous equation, E = mc^2

Given mass, m = 0.112 kg and knowing c = 3.0 x 10^8 m/s, energy E can be determined

E = (0.112 kg)(3.0 x 10^8 m/s)^2

 = 1.008 x 10^16 J

Hope this helps

Joules is the energy equivalent of this .

Explanation:

Mass of hydrogen atoms in 1 kg of water = 112 g= 0.112 kg

Mass and energy related together and that expression was given by the famous scientist named Albert Einstein:

E = Energy related to mass m

c = Speed of the light

m = 0.112 kg , c =

Joules is the energy equivalent of this .

- lead + phosphoric acid = hydrogen + lead(ii) phosphate

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.
