The answer is TRUE.
Energy is an extensive property, which means that it is in proportion to the amount of matter: more mass, more energy.
You can measure, for example, the internal energy per mol or per gram of several compounds or elements. then if you want to know the total internal energy of the system you have to multiply by the number of moles or grams, depending on the unit of the internal energy that you use.
Answer:
56.8cm³
Explanation:
Given parameters:
Measured volume = 54.5cm³
Percentage error = 4.25%
Unknown:
Actual volume of the cylinder = ?
Solution:
The percentage error shows the amount of error introduced into a measurement.
We need to find out this amount of error from the data given.
Error = Percentage error x measured volume
Error = x 54.5 = ±2.32cm³
Since the error introduced = 2.32cm³
Actual volume of cylinder = measured volume ± Error
Since the percentage error quoted as higher 4.25%;
Actual volume = 54.5cm³ + 2.32cm³ = 56.8cm³
Energy in a chemical reaction is not created nor destroyed, it's always conserved based on the law of conservation of energy.

Answer:
Product: propan-1-ol
Explanation:
IIn this case, we have to remember that is a reduction agent. So, this is a <u>reduction reaction</u>. The has the ability to produce <u>hydride ions </u>. This ion can attack the <u>carbonyl group</u> generating a negative charge in the oxygen. In the next step, the negative charge in the oxygen can attack a water molecule to<u> protonate</u> the molecule and produce <u>propan-1-ol</u>.
See figure 1
