Answer:

We produce 2.0 moles of KCl when we have 2.00 moles K and and excess Cl2

Explanation:

Step 1: Data given

Number of moles K = 2.00 moles

Cl2 is in excess, so K is the limiting reactant

Step 2: The balanced equation

2K + Cl2 → 2KCl

Step 3: Calculate moles KCl

For 2 moles K we need 1 mol Cl2 to produce 2 moles KCl

We produce 2.0 moles of KCl when we have 2.00 moles K and and excess Cl2

Atoms are not what during a chemical reaction?

Simora [160]

For example, if Carbon (C) is burnt in Oxygen (O2) to form Carbon Dioxide, a Chemical Reaction occurs. So, during chemical reactions, new product atoms are not created, and old reactant atoms are not destroyed. Atomsare rearranged as bonds are broken and formed.hope that helped

It is the balance between thermal energy and intermolecular forces that determines the state of matter of any substance at room

ExtremeBDS [4]

Answer:

The correct option is;

2) Thermal energy increases by a factor of R

Explanation:

The equipartition energy theorem states that when molecules are in a state of thermal equilibrium, particles within the system posses equal average energy with each degree of freedom which can be known as energy due to a state of having a particular temperature or thermal energy given by the relation

$E_{th}$ = Kinetic energy of translation + Kinetic energy of rotation + Energy of vibration

For a mono-atomic gas, $E_{th}$ = 3/2·n·R·T

For a diatomic gas, $E_{th}$ = 5/2·n·R·T

For a solid element, $E_{th}$ = 3·n·R·T

Therefore, as the temperature is doubled, the thermal energy increases by a factor of R.
