The answers to include the following below:

Hot water has more energy than cold water because it has more internal energy present in it.
The relationship between temperature and the movement of particles is a direct one which means that as temperature increases, the movement of particles also increases and vice versa.
The temperature of a substance is directly proportional to the average kinetic energy of the substance which makes their relationship a direct one.
Water is referred to as pure substance because it contains only one type of molecule.

<h3>What is Temperature?</h3>

This is described as the measure of the hotness or coldness of a substance and is influenced by heat energy.

Temperature has a direct relationship with average kinetic energy and movement of particles which means that an increase in one variable will also lead to a corresponding increase in the other.

This is the therefore the reason why the above answers are correct and the most appropriate.

Charles’ Law can be expressed mathematically as V=kT. If the constant k for 6.0 L of gas is 0.020 L/K (liters per kelvin), what

kozerog [31]

Answer: 300 K

Explanation:

Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

$V\propto T$ (At constant pressure and number of moles)

$V=kT$

Given : V= 6.0 L

k= 0.020 L/K

T=?

$6.0=0.020LK^{-1}\times T$

$T=300 K$

Thus temperature of the gas is 300 K.

Which element is oxidized in the reaction below? fe(co)5 (l) + 2hi (g) fe(co)4i2 (s) + co (g) + h2 (g)?

DanielleElmas [232]

Oxidation state of I is (-1) and for CO it is zero. Let's assume that the oxidation state of Fe in Fe(CO)₄I₂ (s) is x. For whole compound, the charge is zero.

Sum of oxidation numbers in all elements = Charge of the compound.

Here we have 1Fe , 4CO and 2I
hence we can find the oxidation state as;
x + 4*0 + 2*(-1) = 0
x + 0 - 2 = 0
x = +2
Hence the oxidation state of Fe in product Fe(CO)₄I₂ (s) is +2.

Same as we can find the oxidation state (y) of Fe in Fe(CO)₅(s).
y + 5*0 = 0
y = 0

Since oxidation state of Fe increased from 0 to +2, the oxidized element is Fe in the given reaction.

How many sulfur atoms are generated when 9.42 moles of H2S react according to the following equation: 2H2S+SO2→3S+2H2O

8_murik_8 [283]

Answer:

A) 8.51 × 10²⁴

Explanation:

1. Gather all the information

2H₂S + SO₂ ⟶ 3S + 2H₂O

n/mol: 9.42

2. Calculate the moles of S atoms

The molar ratio is 3 mol S:2 mol H₂S

$\text{Moles of S} = \text{9.42 mol H$_{2}$S} \times \dfrac{\text{3 mol S }}{\text{2 mol H$_{2}$S }} = \text{14.13 mol S}$

3. Calculate the atoms of S

$\text{Atoms of S } = \text{14.13 mol S} \times \dfrac{6.022 \times 10^{23}\text{ S atoms}}{\text{1 mol S}} = \mathbf{8.51 \times 10^{24}}\textbf{ S atoms}$
