Answer:

$2HNO_3(aq)+Sr(OH)_2(aq)\rightarrow Sr(NO_3)_2(aq)+2H_2O(l)$

Explanation:

Hello,

In this case, since nitric acid is HNO₃ and strontium hydroxide is Sr(OH)₂ we can represent the balanced chemical reaction by equaling the atoms of strontium, nitrogen, oxygen and hydrogen at both reactants and products as shown below:

$2HNO_3(aq)+Sr(OH)_2(aq)\rightarrow Sr(NO_3)_2(aq)+2H_2O(l)$

Best regards.

Answer:

The balanced reaction between aqueous nitric acid and aqueous strontium hydroxide is Sr(OH)₂ + 2 HNO₃ → Sr(NO₃)₂ + 2 H₂O

Explanation:

A neutralization reaction is one in which an acid (or an acid oxide) reacts with a base (or basic oxide) and the products of which are salt and water.

The general formula for this type of reaction is:

Acid + Base → Salt + Water

In this case, the neutralization reaction that occurs is:

Sr(OH)₂ + HNO₃ → Sr(NO₃)₂ + H₂O

The Law of Conservation of Matter, also called the Law of Conservation of Mass or the Lomonosov-Lavoisier Law, postulates that "mass is neither created nor destroyed, it is only transformed". This means that the reagents interact with each other and form new products with different physical and chemical properties than the reagents because the atoms of the substances are arranged differently.

Then, you must balance the chemical equation. For that, you must first look at the subscripts next to each atom to find the number of atoms in the equation. If the same atom appears in more than one molecule, you must add its amounts

Left side: 1 nitrogen, 3 hydrogen, 5 oxygen and 1 strontium

Right side: 2 nitrogen, 2 hydrogen, 7 oxygen and 1 strontium

The coefficients located in front of each molecule indicate the amount of each molecule for the reaction. This coefficient can be modified to balance the equation, just as you should never alter the subscripts.

By multiplying the coefficient mentioned by the subscript, you get the amount of each element present in the reaction.

In general, hydrogen and oxygen balance in the end. So, starting to balance nitrogen N:

Sr(OH)₂ + 2 HNO₃ → Sr(NO₃)₂ + H₂O

Then:

Left side: 2 nitrogen, 4 hydrogen, 8 oxygen and 1 strontium

Right side: 2 nitrogen, 2 hydrogen, 7 oxygen and 1 strontium

Now, with the nitrogen and strontium being balanced, it is time to balance the hydrogen, obtaining:

Sr(OH)₂ + 2 HNO₃ → Sr(NO₃)₂ + 2 H₂O

Then:

Left side: 2 nitrogen, 4 hydrogen, 8 oxygen and 1 strontium

Right side: 2 nitrogen, 4 hydrogen, 8 oxygen and 1 strontium

Since you have the same amount of each compound on each side of the reaction, the reaction is balanced.

Methane and hydrogen sulfide form when hydrogen reacts with carbon disulfide. Identify the excess reagent and calculate how much

Leno4ka [110]

Answer:

There will be produced 9L of CH4 and 18 L of H2S. There will remain 3 L of CS2

Explanation:

Step 1: Data given

volume of H2 = 36.00 L

volume of CS2 = 12 L

Step 2 = the balanced equation

4H2(g) + CS2(g) → CH4(g) + 2H2S(g)

Step 3: Calculate number of moles of H2

1 mol = 22.4 L

36 L = 1.607 mol

Step 4: Calculate moles of CS2

1 mol = 22.4 L

12 L = 0.5357 moles

Step 5: Calculate the limiting reactant

For 4 moles of H2 we need 1 mol of CS2 to produce 1 mol of CH4 and 2 moles of H2S

H2 is the limiting reactant. It will completely be consumed. ( 1.607 moles)

CS2 is in excess. There will react 1.607/4 = 0.40175 moles

There will remain 0.5357 - 0.40175 = 0.13395 moles of CS2

0.13395 moles of CS2 = 3 L

Step 6: Calculate products

For 4 moles of H2 we need 1 mol of CS2 to produce 1 mol of CH4 and 2 moles of H2S

For 1.607 moles of H2 we'll have 0.40175 moles of CH4 (= 9L) and 0.8035 moles of H2S =(18L)

There will be produced 9L of CH4 and 18 L of H2S. There will remain 3 L of CS2

The process of ____ occurs when magma, lava, or a solute in a solution becomes a solid and the internal components will arrange

satela [25.4K]

Answer:

D. Crystallization

Explanation:

Let's clarify the irrelevant terms first.

unification: This term has nothing to do with chemistry at all
lithification: When the problem mentions magma and lava, you might think that this term is related to the process here. However, 'lithification' do have a precise meaning in geology. It refers to the process where sediments collapses into one single rock under pressure, which has nothing to do with the process mentioned here.

Now, for 2 terms that might confuse you: 'solidification' and 'crystallization' these also has precise scientific definition

Solidification is defined the process where substances in liquid phase changes its phase to solid. On first glance, this answer might seems correct, and yes, it is correct for this question. But not the most correct.

The keyword here is

'the internal components will arrange its self in an organized pattern.'

Crystallization is a special case of Solidification where the atoms or molecules of liquid solidify by spontaneously arrange themselves in periodic, ordered, and organized pattern. It might or might not happen during solidification depending on cooling rate, viscosity of liquid, and other factors.

So, Crystallization is the most correct answer here.

Reika [66]

Answer:

12.9 m³ is the new volume

Explanation:

As the temperature keeps on constant, and the moles of the gas remains constant too, if we decrease the pressure, the volume will increase. If the volume is decreased, pressure will be higher.

The relation is this: P₁ . V₁ = P₂ . V₂

1 atm . 0.93m³ = 0.072 atm . V₂

0.93m³ .atm / 0.072 atm = V₂

V₂ = 12.9 m³

In conclusion and as we said, pressure has highly decreased so volume has highly increased.

Lewis structure for 2O2

Mrrafil [7]

the big number describes the number ratio in a chemical equation

so for example,

2H2 + O2 --> 2H2O means

2 moles of hydrogen reacts with one mole of oxygen to form 2 moles of water

and as you know, the small (subscript) number determines the number of atoms of that element in one molecule of a compound

so I believe that drawing a normal lewis structure ( O=O ) should be correct
