Answer:
Mass, temperature, and phase.
I think temperature because the higher the temperature of a given quantity of a substance, more is its thermal energy. Similarly, for the same temperature, higher mass of a substance will contain more thermal energy.
Answer:
See explaination
Explanation:
The mole balance for a constant-volume batch reactor is given such as, For a first-order isothermal reaction, the time to reach a given conversion is the same for constant-pressure and constant-volume reactors. Also, the time is the same for a reaction of any order if there is no change in the number of moles.

Answer:
a. 0.026 M
Explanation:
Molarity is a measure of the molar concentration of a solution. It can be calculated by using the following formula:
Molarity = n/V
Where;
n = number of moles (mol)
V = Volume of solution (L)
Based on the information provided;
V = 23.2mL = 23.2/1000 = 0.0232 L
n = ?
To get the number of moles of KHP, we use the formula:
mole = mass/molar mass
mole (n) = 0.123/204.2
mole (n) = 0.0006024mol
Molarity = n/V
Molarity = 0.0006024 ÷ 0.0232
Molarity = 6.024 × 10^-4 ÷ 2.32 × 10^-2
Molarity = 6.024/2.32 × 10^(-4--2)
Molarity = 2.59 × 10^-2
Molarity = 0.026 M
Answer:
One molecule is made of two or more atoms bonded together.
Explanation:
Molecule is a substance which is made up chemically by two or more same or different atoms. The atoms joint together in a molecule due to a chemical bond. This chemical bond is formed either by mutual sharing of electrons or transfer of electrons between two atoms.
Examples:
A molecule of H₂O (water) is made up of two atoms of Hydrogen and one atom of Oxygen (H-O-H).
A molecule of CO₂ (Carbon Dioxide) is formed when a carbon atom is bonded to two oxygen atoms via a double bonds (O=C=O).
A molecule of N₂ (Nitrogen Gas) is formed between two nitrogen atoms through a triple bond (N≡N).
