New cards

Quantity of heat/energy released q(j)

q= mcdeltaT

2
New cards

In q= mc delta T M =

mass of water, g

3
New cards

In q= mc delta T C=

Specific heat capacity of water, 4.18g -1 k-1

4
New cards

In q= mc delta T. Delta T =

Increase in temperature (K/c . )

5
New cards

Enthalpy change of combustion (delta H.c, Kjmol -1)

Hc. = -q/n

6
New cards

It isnt actually -q

but put it as exothermic

7
New cards

IN enthalpy change of combusstion q =

quanitity of heat released

8
New cards

IN enthalpy change of combustion, n=

moles of substances combusted, mol
