The heat absorbed to raise temperature : Q = 31350 J

<h3>Further explanation </h3>

Given

m = mass = 150 g

Δt = Temperature difference : 50 °C

Required

Heat absorbed

Solution

Heat can be formulated

<em> Q = m.c.Δt </em>

The specific heat of water = c = 4.18 J/g °C  

Input the value :

Q = 150 x 4.18 x 50

Q = 31350 J

What is the complete ionic equation for H2SO4(aq) + Cal2(aq) -&gt; CaSO4(s) + 2HI(aq)?
eimsori [14]
2H(+) + SO4(2-) + Ca(2+) + 2I(-) -> CaSO4(s) + 2H(+) + 2I(-)
The signs in brackets are the subscripts for the charge of the ion. This is the complete ionic equation. The net ionic equation is:
Ca(2+) + SO4(2-) -> CaSO4

The H 2 produced in a chemical reaction is collected through water in a eudiometer. If the pressure in the eudiometer is 101.3 k
Gnom [1K]

The H2 produced in a chemical reaction is collected through water in a eudiometer. The pressure (kPa) of the H2 gas is 98.89 kPa

The total pressure in a chemical reaction is the total sum of the partial pressure and the vapor pressure of the chemical substances taking place in the chemical reaction.

  • Total pressure = partial pressure of H₂ gas + vapor pressure of H₂O

∴

The vapor pressure of H₂ gas = Total pressure in the eudiometer - partial pressure of H₂O

Given that:

  • The total pressure in the eudiometer = 101.3 kPa
  • The partial pressure of H₂O = 2.41 kPa

The vapor pressure of H₂ gas = 101.3 kPa - 2.41 kPa

The vapor pressure of H₂ gas = (101.3 - 2.41) kPa

The vapor pressure of H₂ = 98.89 kPa

Therefore, we can conclude that the vapor pressure of H₂ is 98.89 kPa.
