I think this is it. and 38 points??
Yes it is a compound because mint ice cream and chocolate chips are being combined together.
The formula of heat added is presented as
Q = m * c * change in (T)
where
Q - the heat added
m - mass
c - specific heat
<span>Change in temperature</span> - (Tf - To)
Basically, in order for us to know the change in heat, the formula is
Change in temperature = T(final) - T(original)
Change in temperature<span> = 36.65 - 24.85
</span>Change in temperature<span> = 11.8 degrees Celcius
</span>
So the change in temperature is 11.8 degrees

Ok so rewrite the equation for yourself :).
N2 + 3H2 -> 2NH3 (Always check if it is balanced).
Ok so we have 2kg of hydrogen conver this to grams and then to moles.
2kg -> 2000g
2000g divide by R.M.M of H2
R.M.M
2H - 2 * 1 -> 2
2000/2 - 1000 moles.
Look at the ratio of H2 to 2NH3.
We see that we get 2NH3 for every H2 therefore the ratio is 1:2.
This means that we HAVE 2000 moles of 2NH3.
At stp. we know that 1 moles = 22.4 Litres
We have 2000 moles that means that we produce 44800 litres of NH3 at stp.
2000 * 22.4 - 44800
Hope this helps :).
