Answer:
1. [OH⁻] = 0.30 M ; 2. [OH⁻] = 1.54x10⁻⁶M ; 3. [OH⁻] = 1.32x10⁻¹³M
Explanation:
Remember the rule:
pH + pOH = 14
pOH = 14 - pH
10*⁻pOH (you have to elevate 10, to -pOH)
10*⁻pOH = [OH⁻]
1. 14 - 13.48 = 0.52
10⁻⁰°⁵² = 0.30
2. 14 - 8.19 = 5.81
10⁻⁵°⁸¹ = 1.54x10⁻⁶
3. 14 - 2.12 = 12.88
10⁻¹²°⁸⁸ = 1.32x10⁻¹³
Viscosity refers to a fuilds resistance to flow.
EX: Honey have higher viscosity than water.
Answer:
Light energy, water and carbon dioxide
Explanation:
First, let’s look at the photosynthesis equation:
light energy + water + carbon dioxide —> glucose + oxygen
The reactants are what go in and are used to create the products.
In photosynthesis, light energy from the sun, water and carbon dioxide are used to make glucose and oxygen.
Therefore, the reactants are light energy, water, and carbon dioxide.
Mg3(AsO4)2
Ca(ClO4)2

[F (I) not sure]
PO₄³
Sorry I don’t know all of them, good luck though! :)
