Juan made the following bar graph shown to represent the relative distances of four different astronomical bodies from Earth. Th

e title of the bar graph is Distance of Bodies in Space from Earth. Four bars are labeled A, B, C, and D. Bar C is the shortest. Bar D is about three times the size of bar C. Bar A is about six times the size of bar C. Bar B is about eight times the size of bar C. If D represents Mars, which of the following could be represented by B and C?

A 1.56 g sample of copper reacts with a mass of oxygen to form 1.95 g of the metal oxide. In another experiment, the molar mass
vitfil [10]

Answer:

The molecular formula of the metal oxide is CuO

Explanation:

Molar mass 79.545 g/m belongs to CuO

This is the reaction:

2Cu(s) + O₂(g) → 2CuO (s)

2 mol of Cu produce 2 mol of CuO

Molar mass Cu = 63.5 g/m

Mass / Molar mass = 1.56 g / 63.5 g/m →0.0245 m

0.0245 mol of Cu produce 0.0245 mole of CuO

Molar mass CuO = 79.545 g/m

Mol . Molar mass = mass

0.0245 m . 79.545 g/m = 1.95 g
