Answer:

A.Vinegar and soda

Explanation:

-A salt is a substance that contains a cation which is a metal ion or an ammonium ion and an anion derived from an acid. It is an ionic compound that can be formed by the neutralization reaction of an acid and a base.

-For example; a reaction between a soluble base sodium hydroxide and an acid dilute sulfuric acid results to the formation of salt sodium salt. There are also other methods of generating a cell apart from neutralization, such as precipitation reactions and direct synthesis among others,

Answer:

Answer is: A. Vinegar and soda.

Neutralization is is reaction in which an acid (in this example vinegar or acetic acid CH₃COOH)  and a base (in this example soda or some other base) react quantitatively with each other.

Balanced chemical reaction of vinegar and soda:

CH₃COOH(aq) + Na⁺(aq) → CH₃COONa(aq) + H⁺(aq).

Sodium acetate (CH₃COONa) is a salt.

Which of the following is an anion?Al3+ Mg2+ O2– H Save
JulijaS [17]
An anion is an ion with a negative charge. The minus sign, when attached to the end of an ionic compound, indicates that this has a negative charge, while a plus sign indicates a positive charge. 

O2- is the only compound listed that satisfied this. It is the anion.
Answer is 02-

Describe in your own words, in terms of particle movement and energy, what occurs when a liquid is cooled to its freezing point.
IRINA_888 [86]
Liquids have free and fast moving particles. Liquids do not take a specific shape unless they are enclosed such as in a bottle. Anyway, since they are free flowing when they freeze, their movement becomes very slow. Eventually the particles will not have room to move as they used to and will be held in one place. The particles are still moving but they are only shaking or vibrating in the same place. You can't even tell this movement is happening, and that is what happens when liquid freezes.

2NO (g) + O2 (g) →2NO2 (g) At equilibrium [NO] = 2.4 × 10 -3 M, [O2] = 1.4 × 10 -4 M, and [NO2] = 0.95 M.
azamat

Answer:

K=1.12x10^9

Explanation:

Hello there!

Unfortunately, the question is not given in the question; however, it is possible for us to compute the equilibrium constant as the problem is providing the concentrations at equilibrium. Thus, we first set up the equilibrium expression as products/reactants:

K=\frac{[NO_2]^2}{[NO]^2[O_2]}

Then, we plug in the concentrations at equilibrium to obtain the equilibrium constant as follows:

K=\frac{(0.95)^2}{(0.0024)^2(0.00014)}\\\\K=1.12x10^9

In addition, we can infer this is a reaction that predominantly tends to the product (NO2) as K>>>>1.

Best regards!
