Enter the chemical equation 2H+(aq)+S2−(aq)→H2S(g). Express your answer as a chemical equation: $2H^+ (aq) + S^{2-}(aq) => H_2S(g)$

<h3 /><h3>Further explanation </h3>

The skill that must be know in chemistry is writing the chemical equations, because these equations are the representations of chemical reactions between substances. The chemical equation consists of substances reacting on the left side and the products formed on the right side, with a right arrow inserted to show a chemical reaction taking place. The phases of the substances are included by writing them as subscripts contained in a parenthesis.

For chemical reactions involving ions, the superscripts are used and the number is usually placed before the charge (i.e. 2+, not +2).

For the given chemical reaction, the complete chemical equation including the phases given by:

$2H^+ (aq) + S^{2-}(aq) => H_2S(g)$

Sulfur $S$ is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent, and nonmetallic. Whereas Hydrogen sulfide $H_2S$ is a colorless chalcogen hydride gas with the characteristic is very poisonous, corrosive, and flammable. Hydrogen $H$ is the most abundant chemical substance in the Universe

Answer : The complete chemical equation is,

$2H^+(aq)+S^{2-}(aq)\rightarrow H_2S(aq)$

Explanation :

As we know that, in a chemical equation the reacting species present on left side and the product formed present on right side and a right arrow inserted between the reactants and product that show a chemical reaction taking place.

In the chemical reaction, the phases of the substances are also included and subscripts and superscripts are also used for the numbers.

For the given chemical reaction, the balanced chemical equation including the phases, is given by:

$2H^+(aq)+S^{2-}(aq)\rightarrow H_2S(aq)$

In which of the following compounds is the mass ratio of chromium to oxygen closest to 1.62 to 1.00?

ohaa [14]

Answer:

The answer to your question is letter A

Explanation:

Data

Mass ratio 1.62 to 1.00

Atomic mass Cr = 52 g

Atomic mass O = 16

Process

1.- Calculate the proportion Chromium to Oxygen to each possible solutions

a) CrO₃ = $\frac{52}{16 x 3} = \frac{52}{48} = 1.08$

b) CrO₂ = $\frac{52}{16 x 2} = \frac{52}{32} = 1.63$

c) CrO = $\frac{52}{16} = 3.25$

d) Cr₂O = $\frac{52 x 2}{16} = \frac{104}{16} = 6.5$

Hydrazine, n2h4, is used as a rocket fuel. in the reaction below, if 80.1 g of n2h4 and 92.0 g of n2o4 are allowed to react, how

Mama L [17]

Answer is: excess of hydrazine is 16 grams.
Chemical reaction: N₂O₄(l) + 2N₂H₄(l) → 3N₂(g) + 4H₂<span>O(g).
</span>m(N₂H₄) = 80,1 g.
m(N₂O₄) = 92,0 g.
n(N₂H₄) = m(N₂H₄) ÷ M(N₂H₄).
n(N₂H₄) = 80,1 g ÷ 32 g/mol.
n(N₂H₄) = 2,5 mol.
n(N₂O₄) = 92 g ÷ 92 g/mol.
n(N₂O₄) = 1 mol; limiting reactant.
From chemical reaction: n(N₂H₄) : n(N₂O₄) = 2 : 1.
n(N₂H₄) = 2 mol reacts.
Δn(N₂H₄) = 2,5 mol - 2 mol = 0,5 mol.
Δm(N₂H₄) = 0,5 mol · 32 g/mol = 16 g.

Explain mitosis and meiosis in your own words.

LuckyWell [14K]

I always remembered the differences by Mitosis sounds like My Toes Is. Which means its body cells reproducing.
And Meiosis is My overies. Which is sex cells reproducing.

Mitosis - The body cell's nucleus makes a copy of its chromosomes. The Chromotids are then pulled to the poles of the cell and split in half, the cell then divides in half into two new cells. Each cell has one pair of chromosomes each.

Meiosis - The sex cells nucleus makes a copy of each chromosome same as before. But then the similar chromosomes group up and swap parts with each other. Making completely new chromosomes. They then split in half again, making two new cells with two different pairs of chromosomes. Which then split apart Once more creating 4 new cells (From the original one) Each with completely random chromosomes.

In the winter , people often buy large bags of rock salt to sprinkle on their walkways . Why do people do this?

slamgirl [31]

The salt causes the water to freeze at a lower temperature. When a solute, aka salt, is introduced to the system, the freezing point is lowered. This makes the water freeze at a lower temperature.
