31) A renewable resource is qualified as things like, Solar, Wind, Hydro-electric, and thermal.
A non-renewable source can be like coal, trees, Gasoline (oil), and petroleum.

32) I don't know what you mean, sorry.

33) Convection Currents cause the plates to move, sometime these currents cause the plates to collide, therefore creating an ... EARTHQUAKE.

Given pH = 8.55 Find: [H3O+] and [OH-] Is this acidic, basic or neutral?
Firlakuza [10]

Answer:

Explanation:

The given pH = 8.55

Unknown:

[H₃O⁺] = ?

[OH⁻] = ?

In order to find these unknowns we must first establish some relationship.

                      pH = -log[H₃O⁺]

                   8.55 = -log[H₃O⁺]

                    [H₃O⁺] = inverse log₁₀(-8.55) = 2.82 x 10⁻⁹moldm⁻³

To find the [OH⁻],

                     pH + pOH = 14

                               pOH = 14 - pH = 14 - 8.55

                                pOH = 5.45

              pOH = -log[OH⁻]

               [OH⁻] = inverse log₁₀ (-5.45) = 3.55 x 10⁻⁶moldm⁻³

The solution is basic because it has more concentration of OH⁻ ions compared to H⁺ ions.

Question 2*
Paraphin [41]

Answer:

Sc(OH)₃ = 96 g/mol

Explanation:

Gram formula mass:

Gram formula mass is the atomic mass of one mole of any substance.

It can be calculated by adding the mass of each atoms present in substance.

Sc(OH)₃:

Atomic mass of Sc = 45 amu

Atomic mas of O = 16 amu

There are three atoms of O = 16 ×3

Atomic mas of H = 1 amu

There are three atoms of H = 1 ×3

Gram formula mass of Sc(OH)₃:

Sc(OH)₃ = 45 ×1 + 16 ×3 + 1  ×3

Sc(OH)₃ = 96 g/mol
