__N2O5+__H2O->__HNO3 What's the reaction?

Chemistry
1 answer:

6 0

Answer:

N₂O₅ + H₂O --> 2HNO₃

This reaction is a combination reaction

Explanation:

I find that making a table is an easy way to balance a table. The table would be something like this:

Reactants (left) Products (right)

N = 2 N = 1

O = 6 O = 3

H = 2 H = 1

The number next the symbol represents how many of atoms of that particular element are present.

The aim is to make the number of atoms of each element on the left side to be equal to the number of atoms of each element on the right side. As we can see, there are 1 more nitrogen than on the right, 3 more oxygen than on the right and 1 more hydrogen than on the left.

So to make the numbers of atoms of each element on right equal to the number of atoms of each element on the left, we have to add a number. This number CANNOT be a subscript number because that would change the reaction.

We can add a 2 in front of the product (this is because there are less atoms in the right side of the equation).

N₂O₅ + H₂O --> 2HNO₃

This means there are now two HNO₃ molecules so every atom in this molecule is basically multiplied by 2. So 1 nitrogen atom becomes two (1 × 2 = 2), 3 oxygen atoms become 6 (3 × 2 = 6) and 1 hydrogen atom becomes 2 (1 × 2 = 2). If we were to make a table again with the following equation - N₂O₅ + H₂O --> 2HNO₃, the table would be as so:

Reactants (left) Products (right)

N = 2 N = 2

O = 6 O = 6

H = 2 H = 2

Now the equation is balanced as we can see the number each type of atom is the same on the right and left side.

In some places timber companies remove all the trees from entire hillside when they are harvesting logs and farmers till the soi
laila [671]

Answer:

The timber companies removing all the trees from entire hillside when they are harvesting logs is a practice that could cause the following when it is time to plant in spring:

1. It could affect the quality of plant needed nutrients in the soil and beneficial microorganism population in the soil which could impact negatively the planting season.

2. Trees serves as protection of soil nutrients against wind erosions, so the soil nutrients would be affected.

The farmers tilling the soil means preparing the soil for a farming season as the following effect:

1. Helps control weed for the planting season.

2. This practice could further encourage soil erosion if not done well.

3. Tilling the soil could make leftover plants from the felling of trees mix well with the soil and also add nutrients to the soil when they decay.

A student needs to convert a volume of 3 Tbsp (tablespoons) to mL. The student finds out that 1 tablespoon is equivalent to 14.7
garri49 [273]

Answer:

The conversion factor is 14.79 mL/Tbsp.

Explanation:

To do an unity conversiton, we can make a factor by a ratio transformation:

3 Tbsp * \frac{14.79 mL}{1Tbsp}

So, the conversion factor is 14.79 mL/Tbsp and 3 Tbsp has 44.37 mL.

Heating a solution of alcohol and water, then collecting the alcohol vapors and condensing them into a liquid with higher alcoho
Sindrei [870]

Answer:

Distillation.

Explanation:

If we are heating a mixture of two miscible liquids and collecting the vapors it means we are separating the two mixtures from each other based on their boiling point differences.

This technique of separation of two liquids based on the difference in boiling point is known as Distillation.

Alcohol will evaporate easily as compared to water as water has stronger influence of hydrogen bond making the inter-molecular forces stronger.

Potassium cyanide is a toxic substance, and the median lethal dose depends on the mass of the person or animal that ingests it.
Artemon [7]

Answer:

88,7 mL of solution

Explanation:

Molarity (Represented as M) is an unit of chemical concentration that is defined as the ratio between moles of solute per liters of solution, that is:

Molarity = moles of solute / Liters of solution

If molarity of KCN solution is 0,0820M and moles of KCN are 7,27x10⁻³ moles:

0,0820M = 7,27x10⁻³ moles / Liters of solution

Liters of solution = 0,0887L = <em>88,7 mL of solution</em>

I hope it helps!
