Answer:
1.17 M
Explanation:
Step 1: Given data
Molar concentration of Li₃PO₄: 0.390 M
Step 2: Write the reaction for the dissociation of Li₃PO₄
Lithium phosphate is a strong electrolyte that dissociates according to the following equation:
Li₃PO₄(aq) ⇒ 3 Li⁺(aq) + PO₄³⁻(aq)
Step 3: Calculate the molar concentration of lithium ions
The molar ratio of Li₃PO₄ to Li⁺ is 1:3. The molar concentration of Li⁺ is 3/1 × 0.390 M = 1.17 M.
The key to answering this question is to realize that you have two polyhedrons combined to form one thus the overall volume would be equal to the sum of the two polyhedron.
Total volume= (volume of prism) + (volume of cuboid)
a) Volume of cuboid (
)=
l = 13ft
w = 18ft
h = 21ft
: . <span>
= 13ft * 18 ft * 21ft
</span> = 4914
b) Volume of Prism (<span>
)</span> =
b = 18ft
h = 16ft
H = 13ft
: .
=
= 1872
Thus Overall Volume = 6786

Answer:
1.) Single Displacement Reaction
2.) Synthesis Reaction
3.) Single Displacement Reaction
4.) Decomposition Reaction
5.) Double Displacement Reaction
Explanation:
Single Displacement Reaction: a reaction in which an element is swapped out for another in a molecule
Double Displacement Reaction: a reaction in which the cation of one molecule is swapped out with the cation of another
Decomposition Reaction: a reaction in which a molecule breaks down into smaller molecules/atoms
Synthesis Reaction: a reaction in which atoms or molecules come together to create a larger molecule
Answer: Mixtures are the substances composed of two or more forms of matter. You can separate them by physical methods. Such examples include a mixture of salt and water, a mixture of sugar and water, different gases, air, etc.
