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.

The number of mole of a molecule is defined as its mass per molar mass. Using # mol = n, mass = m and molar mass = M and given t
Citrus2011 [14]
Given:
n = 0.0021 mol
M = 44 gram/mol

Required: m or the mass of the molecule

Solution:

M = m/n

Rearranging the expression,

m = M x n
m = 44 g/mol x 0.0021 mol

Evaluating the expression and cancelling units, we obtain,

m = 0.0924 grams

M is the molar mass. This value is very useful in chemistry calculations especially in calculating the amounts of reactants and products for a chemical reaction.

Which noble gas will Selenium try to resemble when it becomes an ION?
lapo4ka [179]

Answer:

Krypton

Explanation:

When Selenium forms an ion, it is trying to become krypton which is a noble gas.

Selenium belongs to the oxygen group on the periodic table. In this group, the atoms prefers to gain two electrons to complete their octet. When selenium gains two electrons, its octet is complete.

This will make the atom resemble krypton on the periodic table of elements.

This structure which is an octet confers a special stability on the element.
