Two basic properties of the gas phase are
Molodets [167]
The choices can be found elsewhere and as follows:

A.) a definite shape and a definite volume
B.) a definite shape but no definite volume
C.) no definite shape and no definite volume

I believe the correct answer is option C. Two basic properties of the gas phase would be it has no definite shape and no definite volume. It takes the shape and volume of its container. Hope this answers the question.

An interaction between atoms that holds them together by reducing the potential energy of their electrons
Lemur [1.5K]

Answer:

Chemical bond

Explanation:

Chemical bond is refer to as the interaction existing between two or more atoms, ions or molecules that holds them together by decreasing the potential energy of their electrons. Chemical bond leads to the formation of chemical compounds. Chemical bond may occur as a result of the electrostatic force of attraction that exists between oppositely charged ions such as those in ionic bonds or when electrons are shared such as those in covalent bonds.

In a chemical reaction, substrate molecule A is broken down to form one molecule of product B and one molecule of product C. The
MAVERICK [17]

Answer:

The answer to your question is d. 0.5 M

Explanation:

Data

[A] = 1M

K = 0.5

Concentration of B and C at equilibrium = x

Concentration of A at equilibrium = 1 - x

Equation of equilibrium

                                       k = \frac{[B][C]}{A}

Substitution

                                       0.5 = \frac{[x][x]}{1 - x}

Simplification

                                       0.5 = \frac{x^{2}}{1 - x}

Solve for x

                                      0.5(1 - x) = x²

                                      0.5 - 0.5x = x²

                                       x² + 0.5x - 0.5 = 0

Find the roots             x₁ = 0.5     x₂ = -1

There are no negative concentrations so the concentration of A at equilibrium is  

                       [A] = 1 - 0.5

                             = 0.5 M
