Balance the equations

Chemistry
1 answer:
OLga [1]2 years ago
3 0

Answer: a) H_3PO_4+3NaOH\rightarrow Na_3PO_4+3H_2O

b) PCl_3+3H_2O\rightarrow P(OH)_3+3HCl

c) 2Al+3H_2SO_4\rightarrow Al_2(SO_4)_3+3H_2

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side.

The balanced chemical equations are :

H_3PO_4+3NaOH\rightarrow Na_3PO_4+3H_2O

PCl_3+3H_2O\rightarrow P(OH)_3+3HCl

2Al+3H_2SO_4\rightarrow Al_2(SO_4)_3+3H_2

If the change in entropy of the surroundings for a process at 451 k and constant pressure is -326 j/k, what is the heat flow abs
Arisa [49]

If the change in entropy of the surroundings for a process at 451 k and constant pressure is -326 j/k, then heat flow absorbed (in kj) by the system is -147.026kJ.

<h3>What is entropy? </h3>

The entropy of particle is defined as how random it move. It shows the randomness of the system or may be disorders of the system. It is used to measure the unavailable energy for performing useful work.

Unit of entropy = J/K

<h3>Formula:</h3>

∆s = ∆Q/T

where,

∆s = change in entropy of the surrounding = -326J/K

∆Q = heat absorbed from surrounding

T = Temperature = 451K

∆Q = ∆s × T

∆Q = -326 × 451

∆Q = 147,026 J

∆Q = 147.026 kJ

Thus we find that the heat absorbed by the system is 147.026 kJ.
