3. for the following reaction, calculate how many grams of each product are formed when 4.05 g
of water is used.
2 h2o → 2 h2 + o2

Explanation:

We will need a balanced chemical equation with masses and molar masses, so, let's gather all the information in one place.

MM:                    2.016    32.00

            2H₂O ⟶ 2H₂   +   O₂

m/g:      4.05

1. Mass of hydrogen

(a) Moles of H₂O

(b) Moles of H₂

(c) Mass of H₂

2. Mass of oxygen

(a) Moles of O₂

(b) Mass of O₂

answer; /// i do believe that the correct answer is (c)nuclear bond

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
