Answer:
C. The ratio of the substances coefficients equal the ratio is the number of moles
Explanation:
Answer:
Change in temperature, ΔT = 22.8°C,
Reaction is endothermic.
Explanation:
The amount heat is given by the formula;
q = m×c×ΔT
Where, q is the amount of heat
m is the mass of a substance
c is the specific heat capacity
ΔT is the temperature change.
In this case, making ΔT the subject of the formula, we get;
ΔT = q/m×c
but; q = 868 Joules
m = 15.6 g
c = 2.44 J/g°C
Therefore;
ΔT = 868 J/(2.44 J/g°C × 15.6 g)
= 22.8 °C
Therefore, the temperature change for ethanol is 22.8 °C
This means there is an increase in temperature and therefore the reaction is endothermic.
Answer: no
Explanation:
It could be dangerous since you don't know what substance are you adding.it may end up in an explosion
I hope this helps :)
