Interpretation: The given table must be filled by identifying the respective missing masses using the law of conservation of mass.
Concept Introduction: In a chemical change, the
Answer to Problem 11STP
Mass of Magnesium (g) | Mass of Oxygen (g) | Mass of magnesium oxide (g) |
5 | 3.30 | 8.3 |
6.5 | 4.30 | 10.8 |
13.6 | 9.00 | 22.60 |
19.00 | 12.50 | 31.5 |
Explanation of Solution
Given:
Mass of Magnesium (g) | Mass of Oxygen (g) | Mass of magnesium oxide (g) |
5 | 3.30 | 8.3 |
6.5 | (a) | 10.8 |
13.6 | 9.00 | (b) |
(c) | 12.50 | 31.5 |
According to the law of conservation of mass, mass is conserved in any chemical or physical change. The mass of reactants is always equal to the mass of products during any
(a)
(b)
(c)
Therefore, the complete table is:
Mass of Magnesium (g) | Mass of Oxygen (g) | Mass of magnesium oxide (g) |
5 | 3.30 | 8.3 |
6.5 | 4.30 | 10.8 |
13.6 | 9.00 | 22.60 |
19.00 | 12.50 | 31.5 |
