Answer:
A
Explanation:
The products of a chemical equation is what is being experimented with. However, the results in which you get are known as your solution.
Since it was specifically stated that heat is released, therefore
heat is located on the right side of the reaction equation. Also stating the
states of each compound, the complete balanced reaction would be:
C2H5OH (l) + 3 02 (g) -----> 2 CO2 (g) + 3 H2O (g) + 1235
kJ
<em>Q=mcΔT</em>
<em>Q=15.2g(0.397</em><span><em>J/g C)(40.3-21)</em>
<em>Q=</em><u>116.5J</u></span>
Answer:
D
Explanation:
Friction plays an important part in many everyday processes. For instance, when two objects rub together, friction causes some of the energy of motion to be converted into heat.
Lemonade is a mixture because sugar, water and lemons are combined together without a chemical reaction taking place.
