Answer : b. mixture
<h3>Further explanation</h3>
Element and compound are included in pure substance where the composition is the same in each part
Elements are made up of 1 type of atom, while the compounds of 2 or more types of atoms
, both can be represented in the form of chemical symbols
A mixture is a combination of substances. The properties of a substance in the mixture component are unchanged
The mixture can be a homogeneous mixture or a heterogeneous mixture
- the homogeneous mixture if each part has the same composition
- the heterogeneous mixture if each part has a different composition
Solution including into Homogeneous mixture, while suspension into a heterogeneous mixture
So a term that could refer to heterogeneous matter : b. mixture
Ions are electrically charged particles formed when atoms lose or gain electrons. They have the same electronic structures as noble gases. Metal atoms form positiveions, while non-metal atoms form negative ions. The strong electrostatic forces of attraction between oppositely charged ions are called ionic bonds.
Answer:
pOH = 11.5
[H⁺] = 0.003 M
[OH⁻] = 3 × 10⁻¹² M
Explanation:
The computation is shown below:
Given that
pH = 2.5
Based on the above information
We know that
pH + pOH = 14 ⇒ pOH = 14 - pH
pOH = 14 - 2.5
pOH = 11.5
[H⁺] = 10^(-pH) = 10^(-2.5)
[H⁺] = 0.003 M
[OH⁻] = 10^(-pOH)
= 10^(-11.5)
= 3 × 10⁻¹² M
[OH⁻] = 3 × 10⁻¹² M
Hence, the above represents the answer
When the person said"nuke it" they are not referring to what they are going to nuke. That is why it is incorrect.
