Chemistry

Advocard [28]3 years ago
6 0

Answer:

8.75×10¹³ mg

Explanation:

From the question given above, we obtained:

Mass (in Kg) = 8.75×10⁷ Kg

Mass (in mg) =?

Next, we shall convert 8.75×10⁷ Kg to grams (g). This can be obtained as follow:

1 Kg = 1000 g

Therefore,

8.75×10⁷ Kg = 8.75×10⁷ Kg × 1000 g/1 kg

8.75×10⁷ Kg = 8.75×10¹⁰ g

Therefore, 8.75×10⁷ Kg is equivalent to 8.75×10¹⁰ g.

Finally, we shall convert 8.75×10¹⁰ g to mg. This can be obtained as illustrated below:

1 g = 1000 mg

Therefore,

8.75×10¹⁰ g = 8.75×10¹⁰ g × 1000 mg/ 1 g

8.75×10¹⁰ g = 8.75×10¹³ mg

Thus, 8.75×10⁷ Kg is equivalent to 8.75×10¹³ mg.

Balance the equation ___Fe+__O2–>___Fe2O3
Sever21 [200]

Answer:

4 Fe + 3 O2 = 2 Fe2O3

Explanation:

In order to balance the equation, there should be equal number of iron atoms (Fe) and oxygen atoms (O2) in Iron(III) oxide (Fe2O3).

Since there are two atoms of Oxygen in 1 oxygen molecule and 3 atoms of Oxygen in 1 Iron Oxide, the least common multiples of the total oxygen atoms which would equal each other is 6 atoms of Oxygen. This results in 3 molecules of O2 and 2 molecules of Fe2O3.

In order to balance out the amount of iron in iron oxide, you must then calculate the total iron atoms in iron oxide; since there are 2 atoms of Fe in each molecule of Iron Oxide and there is 2 molecules of Fe2O3, the total is 2*2 = 4 atoms of iron, Fe.

In order to get 4 atoms of iron from molecules of Fe, you need 4 molecules of Fe, since each molecule contains 1 Fe.

If the a of a monoprotic weak acid is 1. 2×10^−6. What is the [H] of a 0. 31 m solution of this acid?
Vanyuwa [196]

The pH of the solution of the given acid is 3.099

Let  HX  be the weak acid:

HX ⇌  H^{+}+ X^{-}

For which:

K_{a} = [ H^{+}][ X^{-}] / [HX]

If  K_{a} lies in the range 10^{-4} - 10^{-10}we can assume that the equilibrium concentrations used in the expression are a good enough approximation to the initial concentrations.

Rearranging and taking negative logs of both sides gives:

pH = \frac{1}{2} [pK_{a} - loga]

a is the concentration of the acid.

pK_{a} =-logK_{a} = -log (2×10^{-6}) = 5.69

pH = \frac{1}{2} [5.69- (-0.508)]

pH = 3.099
