Answer : The mole ratio of hydrogen to ammonia is, 3 : 2

Explanation :

Balanced chemical reaction : The chemical reaction in which the number of individual atoms of an element present on the reactant side always be equal to the number of individual atoms of an element present on the product side.

The given balanced chemical reaction is,

$N_2(g)+3H_2(g)\rightarrow 2NH_3(g)$

From the balanced chemical reaction, we conclude that 1 mole of $N_2$ gas react with 3 moles of $H_2$ gas to give 2 moles of $NH_3$ gas as a product.

The mole ratio of nitrogen, hydrogen and ammonia is, 1 : 3 : 2

Therefore, the mole ratio of hydrogen to ammonia is, 3 : 2

(b) What is the pH of 0.40 M triethylammonium chloride, CH₃ (CH₂)₃ NHCl ?

Valentin [98]

pH of 0.40M triethylammonium chloride is 5.90.

A solution's acidity may be determined by looking at its pH, which is a measurement of hydrogen ion concentration. Pure water slightly separates into ions with roughly equal amounts of hydrogen and hydroxyl (OH) ions. [H+] is 107 for a neutral solution, or pH = 7.

<h3>Given : </h3>

Concentration of triethylammonium chloride = 0.40M

pH = ?

<h3>Solution: </h3>

(CH3CH2)3NHCl ------> (CH3CH2)3NH⁺ + Cl⁻

(CH3CH2)3NH⁺ will react with water to give H3O⁺ .

(CH3CH2)3N will have a Kb = 5.2 x 10 ^(-4)

Kw = Kb x Ka

=> Ka = Kw / Kb = 10^(-14) / 5.2 x 10 ^(-4)

=> Ka = 1.92 x 10^(-11)

so by the reaction we have ,

Ka = x²/(0.40 - x)

=> x = 1.2393 x 10 ^(-6)

now, pH = -log( [H3O⁺]) = - log ( 1.2393 x 10 ^(-6)) = 5.906

Answer:

The heat generated per gram of sample in calories is 0.87 g

Explanation:

Given that,

A calorimeter made from a can is used to measure the calories in a peanut.

During the experiment, the measured calories were 35% of the true/accepted value given by references

Suppose, the mass of peanut is 0.4 g and find the

We need to calculate the heat generated per gram of sample in calories

Using formula of heat generated

$q=\dfrac{q_{penut\ calorimeter}}{m_{peanut}}$

Put the value into the formula

$q=\dfrac{0.35}{0.4}$

$q=0.87\ g$

Hence, The heat generated per gram of sample in calories is 0.87 g

What is the solubility product (or ion-product), Ksp, expression at equilibrium for calcium phosphate, Ca3(PO4)2?

Gnoma [55]

Answer : The expression for solubility constant for this reaction will be,

$K_{sp}=[Ca^{2+}]^3[PO_4^{3-}]^2$

Explanation :

Solubility product : It is defined as the product of the concentration of the ions that present in a solution raised to the power by its stoichiometric coefficient in a solution of a salt. This takes place at equilibrium only.

The solubility product constant is represented as, $K__{sp}$ .

The dissociation of calcium phosphate is written as:

$Ca_3(PO_4)_2\rightleftharpoons 3Ca^{2+}+2PO_4^{3-}$

The expression for solubility constant for this reaction will be,

$K_{sp}=[Ca^{2+}]^3[PO_4^{3-}]^2$
