<h3>
Answer:</h3>
pH = 8.66
<h3>
Explanation:</h3>
- The pH refers to the acidity or alkalinity of a solution.
- It is calculated by getting the negative logarithm of Hydrogen ions concentration.
In this case;
we are given [OH⁻] as 4.6 x 10^-6 M
We are required to calculate the pH
We need to know that;
pH + pOH = 14
pOH = -log[OH⁻]
To get the pH we can calculate the pOH first,
pOH = -log[4.6 x 10^-6 M]
= 5.34
but, pH + pOH = 14
Therefore, pH = 14 - pOH
= 14 - 5.34
= 8.66
Therefore, the pH of the solution is 8.66
D the lowest amount of energy
I think a is the correct answer
Lithium is a metal and Fluorine is a non-metal, which means they will form an ionic bond. An ionic bond is when a metal atom donates its electron complete to a non-metal atom.
Answer:
1. Element - a substance that is made from only one type of atom
An element is made up of only one type of atoms and known for its unique properties than other elements.
2. Heterogeneous - composed of dissimilar parts which can be separated easily and which are unevenly distributed in the mixture
3.Homogenous - even distribution of parts throughout the whole mixture; not easily separated into individual components.
4. Product - the substance created as a result of a chemical reaction
Products are the final substance that created as a result of a chemical reaction.
5. Reactant - one of the starting substances (ingredients) that is involved in a chemical reaction
Reactants are the starting substance that takes part in a chemical reaction.
6. Solute - the substance that is being dissolved.
A Solute is a substance that is being dissolved in the solvent to make a solution.
7. Solvent - the substance that does the dissolving
A solvent is the medium in which the solute is being dissolved to make the solution.
