Strontium phosphate reacts with sulfuric acid to form strontium sulfate and phosphoric acid. what is the coefficient for sulfuri
2 answers:
<u>Answer:</u> The coefficient of sulfuric acid in the given equation is 3.
<u>Explanation:</u>
The chemical equation for the reaction of strontium phosphate and sulfuric acid follows:
By Stoichiometry of the reaction:
1 mole of strontium phosphate reacts with 3 moles of sulfuric acid to produce 3 moles of strontium sulfate and 2 moles of phosphoric acid.
The given reaction is a type of double displacement reaction because here exchange of ions takes place.
Hence, the coefficient of sulfuric acid in the given equation is 3.

42.34 g of water could be warmed from 21.4°C to 43.4°C by the pellet dropped inside it
Heat loss by the pellet is equal to the Heat gained by the water.
….(1)
where, is the heat gained by water
is the heat loss by pellet
= mCΔT
where m = mass of water
C = specific heat capacity of water = 4.184 J/g-°C
ΔT = Increase in temperature
ΔT for water = 43.4 - 21.4 = 22°C
= m × 4.184 × 22 …. (2)
Now
=
×ΔT
where = Heat capacity of pellet = 56J/°C
Δ T for pellet = 43.4 - 113 =- 69.6°C
= 56 × -69.6 = -3897.6 J
From equation (1) and (2)
-m× 4.184 × 22 =-3897.6
m= 42.34 g
Hence, 42.34 g of water could be warmed from 21.4 degrees Celsius to 43.4 degrees Celsius by the pellet dropped inside it.
