How many grams of aluminum phosphate is produced from 7.5 g of lithium phosphate in this balanced equation? 2Li3PO4 + Al2(SO4)3

iren [92.7K]

7.8049856 g of aluminium phosphate is produced from 7.5 g of lithium phosphate in this balanced equation.

<h3>What are moles?</h3>

A mole is defined as 6.02214076 × $10^{23}$ of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

Given data:

$2Li_3PO_4 + Al_2(SO_4)_3$ → $3Li_2SO_4 + 2AlPO_4$

Moles of 7.5 g of lithium phosphate.

The molar mass of lithium phosphate is 115.79 g/mol.

Moles = $\frac{mass}{molar \;mass}$

Moles = $\frac{7.5 g}{115.79 g/mol}$

Moles = 0.06477243285

Now we will compare the moles of $AlPO_4$ with $Li_3PO_4$ .

$Li_3PO_4$ : $AlPO_4$

2 : 2

0.385 : 2÷2× 0.064 = 0.064 mol

Mass of $AlPO_4$ :

Mass of $AlPO_4$ = moles × molar mass

Mass of $AlPO_4$ =0.064 mol × 121.9529 g/mol

Mass of $AlPO_4$ = 7.8049856 g

Hence, 7.8049856 g of aluminium phosphate is produced from 7.5 g of lithium phosphate in this balanced equation.

For the reaction 2NH3(g)↽−−⇀3H2(g)+N2(g) 2 NH 3 ( g ) ↽ − − ⇀ 3 H 2 ( g ) + N 2 ( g ) the equilibrium concentrations were found

forsale [732]

Answer:

0.324

Explanation:

The following data were obtained from the question:

Concentration of NH3, [NH3] = 0.25 M

Concentration of H2, [H2] = 0.3 M

Concentration of N2, [N2] = 0.75 M

Equilibrium constant (Kc) =.?

The balanced equation for the reaction is given below:

2NH3 <==> 3H2 + N2

The equilibrium constant, Kc for a given reaction is the ratio of the concentration of the products raised to their coefficient to the concentration of the reactants raised to their coefficient. Thus, the equilibrium constant for the above reaction can be obtained as illustrated below:

Kc = [H2]³ [N2] / [NH3]²

Concentration of NH3, [NH3] = 0.25 M

Concentration of H2, [H2] = 0.3 M

Concentration of N2, [N2] = 0.75 M

Equilibrium constant (Kc) =.?

Kc = [H2]³ [N2] / [NH3]²

Kc = [0.3]³ × [0.75] / [0.25]²

Kc = (0.027 × 0.75) / 0.0625

Kc = 0.02025 / 0.0625

Kc = 0.324

Therefore, the equilibrium constant for the reaction is 0.324

Some chemical reactions releases energy other store energy what important chemical reaction storage energy?

olganol [36]

Answer:

A chemical reaction that stores energy is called an endothermic reaction. More energy might be released as products form than the energy needed to break the reactants apart. This chemical reaction will release energy. In other words, it will be an exothermic reaction.
