(a) 37Q = 37Rb(Rubidium)
     35R = 35Br(Bromine)
Formula of the compound is : RbBr(Rubidium Bromide)

(b) 8Q = 8O(Oxygen)
     13R = 13Al(Aluminum)
Formula of the compound is : Al2O3(Aluminum Oxide)

(c)20Q = 20Ca(Calcium)
    53R = 53I(Iodine)
Formula of the compound is : CaI2(Calcium Iodide)

Answer:

(a) RbBr - rubidium bromide.

(b) Al_2O_3 - aluminium oxide.

(c) CaI_2 - calcium iodide.

Explanation:

Hello,

(a) In this case, the elements having 37 and 35 as the oxidation states are rubidium and bromine respectively, in such a way the formed compound, due their gatherable oxidation states (+1 and -1 respectively) is the following binary salt:

RbBr - rubidium bromide.

(b) In this case, the elements having 8 and 13 as the oxidation states are aluminium and oxygen respectively, in such a way the formed compound, due their gatherable oxidation states (+3 and -2 respectively) is the following basic oxide:

Al_2O_3 - aluminium oxide.

(c) In this case, the elements having 20 and 53 as the oxidation states are calcium and iodine respectively, in such a way the formed compound, due their gatherable oxidation states (+2 and -1 respectively) is the following binary salt:

CaI_2 - Calcium iodide.

Best regards.

What is the answer to this question
Stels [109]

Answer:

38 kg/m³

0.038 g/mL

Explanation:

Volume of a cube is the side length cubed.

V = s³

Given s = 0.65 m:

V = (0.65 m)³

V ≈ 0.275 m³

The mass is 10.5 kg.  The density is the mass divided by volume:

ρ = (10.5 kg) / (0.275 m³)

ρ ≈ 38 kg/m³

Or:

ρ ≈ 0.038 g/mL
