Given the equation representing a reaction at equilibrium: N2(g) + 3H2(g) 2NH3(g) What occurs when the concentration of H2(g) is increased?

Answers

Answer 1

Answer: Given the equation representing a reaction at equilibrium: N2(g) + 3H2(g) = 2NH3(g). When the concentration of the hydrogen gas is increased, the equilibrium will tend to go to the products or to the forward reaction. Therefore, more products are formed.

Further explanation

Mixtures are materials composed of two or more kinds of substances that still possess their original properties. Mixtures can also be said to represent a combination of several substances, elements or compounds

There are two types of mixtures, i.e., homogeneous mixture (or solution) and heterogeneous mixture.

Homogeneous mixture: mixture which each part contains a similar amount of solute, for example, vinegar acid solution, sugar solution, and salt solution.
Heterogeneous mixes: mixtures of which each part contains an unequal amount of solute, for example, river water, sewage water, and coffee drinks.

The solution is a homogeneous mixture of two or more substances that dissolve one another and each of the constituent substances cannot be distinguished physically anymore.

The solution consists of two components, i.e., solute and solvent.
For example, a salt solution consists of salt as a solute and water as a solvent.

In chemistry, we already know the phase of matter or state of matter, i.e., solid (s), liquid (l), gas (g), and aqueous (aq). Every chemical solution in a reaction is labeled as an aqueous phase, e.g, $\boxed{ \ NaCl_((aq)) \ }$ as a salt solution.

Consider the following examples:

$\boxed{ \ Fe_((s)) \ }$ as a solid metal iron, an element.
$\boxed{ \ H_2O_((l)) \ }$ as liquid water.
$\boxed{ \ H_2O_((s)) \ }$ as ice solids.
$\boxed{ \ H_2O_((g)) \ }$ as water vapor with a gaseous phase.
$\boxed{ \ H_2O_((l)), H_2O_((s)), H_2O_((g)) \ }$ are compounds of the same chemical formula but different phases.

The answer is D. Stars are formed from interstellar clouds because of the Law of Universal Gravitation. The interstellar clouds are termed as nebula. When other stars dies a supernova occurs then the gravity from this pushes matter into the clouds until it cannot overcome the gravitational pull and it collapses which heats matter up forming a star.

Solid aluminum and gaseous oxygen react in a combination reaction to produce aluminum oxide: In a particular experiment, the reaction of 2.5 g of Al with 2.5 g of O2 produced 3.5 g of Al2O3. The % yield of the reaction is __________.

Answers

Answer:

The % yield of the reaction is 73.8 %

Explanation:

To solve this, we list out the given variables thus

Mass of aluminium in the experiment = 2.5 g

mass of oxygen gas in the experiment = 2.5 g

Molar mass of aluminium = 26.98 g/mol

molar mass of oxygen O₂ = 32 g/mol

The reaction between aluminium and gaseous oxygen can be written as follows

4Al + 3O₂ → 2Al₂O₃

Thus four moles of aluminium forms two moles of aluminium oxide

Thus (2.5 g)÷(26.98 g/mol) = 0.093 mole of aluminium and

(2.5 g)÷(32 g/mol) = 0.078125 moles of oxygen

However four moles of aluminium react with three moles of oxygen gas O₂

1 mole of aluminum will react with 3/4 moles of oxygen O₂ and 0.093 mole of aluminium will react with 0.093*3/4 moles of O₂ = 0.0695 moles of Oxygen hence aluminium is the limiting reagent and we have

1 mole of oxygen will react with 4/3 mole of aluminium

∴ 0.078125 mole of oxygen will react with 0.104 moles of aluminium

Therefore 0.093 mole of aluminium will react with O₂ to produce 2/4×0.093 or 0.0465 moles of 2Al₂O₃

The molar mass of 2Al₂O₃ = 101.96 g/mol

Hence the mass of 0.0465 moles = number of moles × (molar mass)

= 0.0465 moles × 101.96 g/mol = 4.74 g

The of aluminium oxide Al₂O₃ is 4.74 g, but the actual yield = 3.5 g

Therefore the Percentage yield = $(actual yield )/(theoretical yield)$ ×100 = $(3.5)/(4.74)$ × 100 = 73.8 % yield

3) B. basic
4) C. HCl is a strong acid; HC2H3O2 is a weak acid.
5) Kb = [OH-][C5H5NH+]/[C5H5N]

Answer: 1. B. 1.3

2. D. self-ionization

3. A. acidic

4. HCl is a weak acid; $CH_3COOH$ is a weak acid.

5. A. $K_b=([OH^-][C_5H_5NH^+])/([C_5H_5N])$

Explanation:

1. pH is the negative logarithm of hydrogen ion concentration.

$pH=-log[H^+]$

Given: $[H^+]=5.0* 10^(-2)=0.05$

$pH=-log[0.05M]=1.30$

2. An acid is a substance which donates $H^+$ ions when dissolved in water.

A base is a substance which donates $OH^-$ ions when dissolved in water.

Thus as water ionizes to give both ions, it acts as both acid and base.

$H_2O\rightarrow H^++OH^-$ which is called as self ionization.

3. pH is the measure of acidity or alkalinity of a solution. \Acids have pH less than 7, neutral solutions have pH of 7 and basic solutions have pH more than 7.

As the given solution has a pH of 6.8 which is less than 7, it is an acidic solution.

4. Strong acids are those acids which undergo complete dissociation when dissolved in water.

$HCl\rightarrow H^++Cl^-$

Weak acids are those acids which do not undergo complete dissociation when dissolved in water.

$CH_3COOH\rightleftharpoons CH_3COO^-+H^+$

5. Dissociation constant is the ratio of product of concentration of products to the product of concentration of reactants each raised to their stochiometric coefficients.

$C_5H_5N+H_2O\rightarrow C_5H_5NH^++OH^-$

$K_b=([OH^-][C_5H_5NH^+])/([C_5H_5N])$

The concentration of water is ignored as it is in large excess and thus does not effect the dissociation of pyridine.
