Answer:
Q=msΔT
rearranging in terms of temperature gives:
ΔT=Q/ms
=1320j/(230g×0.338(j/g°C))
=16.97967584°C
=> ΔT=17.0°C
Answer:
Coefficient in front of the
in the balanced equation - 4
Explanation:
The unbalanced reaction is shown below as:-
On the left hand side,
There are 1 nitrogen atom and 3 hydrogen atoms and 3 oxygen atoms
On the right hand side,
There are 1 nitrogen atom and 2 hydrogen atoms and 2 oxygen atoms
Thus,
Right side,
must be multiplied by 6 and
by 4
Left side,
is multiplied by 5 and
by 4 so to balance the whole reaction.
Thus, the balanced reaction is:-
<u>Coefficient in front of the
in the balanced equation - 4</u>
