a. An oxidation reaction. An oxidation reaction is a type of chemical reaction that involves a transfer of electrons between two species.
Answer:
water vapor
because solid ice is a matter
<u>Given</u> :
- Amount = 20 kg
- Heat energy absorbed = 237,000 J
- Temperature change = 15 °C
<u>Formula applied</u> :
- Q = absorbed heat
- m = mass
- c = specific heat capacity
- ΔT = temperature change
Let's solve for c !
⇒ 237,000 = 20 × c × 15
⇒ c = 237,000 ÷ 300
⇒ 
∴ The specific heat capacity of granite is <u>790 J kg⁻¹ K⁻¹</u>.
The electronic configuration of organic compounds depends on the orbitals of their atoms and molecules.
<h3>What is electronic configuration?</h3>
The expression 'electronic configuration' makes reference to the spacial arrangement of electrons in distinct energy orbitals of an atom/molecule.
The orbitals are designed with numbers and letters, whereas the amount of electrons in each orbital is expressed as superscripts (e.g., 1s² 2s² 2p² in the C atom that form glucose).
In conclusion, electronic configuration of organic compounds depends on the orbitals of their atoms and molecules.

Answer:
a) The answer is 100.39 u
b) The assumptions are that the two gases are at the same pressure and that both have the same temperature.
Explanation:
a) the molecular weight of the argon is 39,948 u, to calculate the mass of the unknown compound we will divide the quantities of the known masses, both that of the argon and the unknown mass and then multiply it by the molecular weight of the argon, as follows:
unknown gas = (8.102/3.224) * 39.948 u = 100.39 u
b) The assumptions are that the two gases are at the same pressure and that both have the same temperature.
