of carbon

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.

mass of sugar=

To calculate the moles, we use the equation:

1 mole of sugar contains = of carbon

0.116 mole of sugar contains = of carbon

the formula would be mgso4

mgso[subscript]4

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.
