Do this
3.35mol HCl | 34.46g HCl
------------------------------------
1 | 1mol HCl
Multiply all the numbers on top by all the numbers on bottom.
Heat energy is supplied to materials and can cause an increase in temperature of the material. the formula is as follows
H = mcΔt
where H - heat energy
m - mass of material
c - specific heat
Δt - change in temperature - 40.0 °C - 22.5 °C = 17.5 °C
substituting the values
H = 175 g x 0.234 Jg⁻¹°C⁻¹ x 17.5 °C
H = 716.6 J
716.6 J is required
Jesus loves you !! Repent today and turn away from your sins Thanks
