<h3><u>Answer;</u></h3>
Coefficient
<h3><u>Explanation;</u></h3>
- Coefficients are the numbers in front of the chemical formulas.
- For example in 3H2O ,the three infront of the water molecule is called the coefficient.
- These numbers give two very important pieces of information about a chemical equation. The coefficients give the number of molecules (or atoms) involved in the reaction.
- Additionally, coefficient give the number of moles of each substance involved in the reaction.
The correct answer is condensation
That is because energy is used to break bonds, so condensation where bonds are made actually loses energy because it turns into liquid.
Answer:
B. HOPE THIS HELPED SENSI
Explanation:
P: ?
V: 35,5L = 35,5 dm³
n: 0,54 mol
R: 83,14 hPa·dm³/mol·K
T: 223K
..................
pV = nRT
p = nRT/V
p = (0,54×83,14×223)/35,5
p = 282,02 hPa
