The number of solid precipitate that will be formed is 37.08 g
calculation
write the equation for reaction
=Hg(NO3)2 +Na2SO4 = HgSO4(s) +2NaNO3(aq)
find the moles of each reactant
moles ofHg(NO3)2=126.27/324.6= 0.389 moles
moles of Na2SO4=17.796/142=0.125 moles
NaSO4 is the limiting reagent and by use of mole ratio of NaSO4:HgSO4 which is 1:1 therefore the moles of H2SO4 is also= 0.125 moles
mass HgSO4=moles x molar mass
=0.125 x296.65= 37.08g
Answer:
Explanation:
Q = m × Cp × delta T
Where,
Q is the heat gained by water
m is the mass of water
Cp = specific heat capacity of water
= 4.18 kJ per kilogram per degree Celsius (J/kg°C).
This means that it takes 4,180 J to raise the temperature of 1 kg of water by 1°C
delta T is the difference in temperature
A.
The smaller beaker had a bigger temperature rise because the same energy has been given to a smaller number of water particles in the beaker than those particles in the large beaker so each particle is moving faster than those in the other beaker.
B.
Since both beakers were heated at the same time, they both gain the same amount of energy.
Qlarge = Qsmall
