Which of the following statements is true?

Chemistry
1 answer:
Anna007 [38]3 years ago
6 0

Answer:

C. Lithium is most easily oxidized of the metals listed on the activity series and therefore it will most easily give electrons to metal cations

Explanation:

"Lithium" is a type of alkali metal that has a "single valence electron." Since it is a reactive element, it easily gives up an electron when it is combined with other elements. Such giving up of electron is meant to create compounds or bonds.

Among the common metals listed, "lithium" is the most easily oxidized. This means that it donates its electrons immediately. Such combination makes it exist as a<em> "cation"</em> or <em>"positively-charged."</em>

So, this explains the answer.

What effect does nuclear radiation have on atoms?
marishachu [46]

Answer:

It ionizes atoms.  

Step-by-step explanation:

There are three types of nuclear radiation:

  • α rays
  • β rays
  • γ rays

All of these have enough energy that they can remove an electron from an atom and cause it to become charged or ionized.

A is <em>wrong</em>. Ionizing radiation does not have enough energy to split atoms.

B is <em>wrong</em>. Nuclear radiation does not involve burning — the reaction of atoms with oxygen.

The maximum amount of product that can be produced from a given amount of reactant is known as ______________________.
vova2212 [387]

Answer:

The answer to your question is Theoretical yield

Explanation:

Theoretical yield is the quantity of a product obtain considering that all the reactants will be converted into products. The theoretical yield considers that the reaction is 100% effective, but this is not true most of the chemical reactions have a yield of 80 % or lower.

What is the molar solubility in water of ag2cro4 ? (the ksp for ag2cro4 is 8 x 10-12. )
nikitadnepr [17]

The molar solubility in water of Ag₂CrO₄ is 2.52 * 10⁻⁴ M .

<h3>How do you define Solubility ?</h3>

The measure of the degree to which a substance gets dissolved in a solvent to become a solution.

The formula for determination of molar solubity is

\rm K_{sp} =  [A^+]^a [B^-]^b

\rm K_{sp}          = solubility product constant

\rm [A^+]^a  =     cation in an aqueous solution

\rm  [B^-]^b  = anion in an aqueous solution

a, b          = relative concentrations of a and b

We have the data given as

\rm K_{sp} for Ag₂CrO₄ is 8 x 10⁻¹²

For Silver chromate , the solubility would be only one-half of the Ag⁺ concentration.

We denote the solubility of Ag₂CrO₄ as S mol L⁻¹.

Then for a saturated solution, we have

[Ag⁺]=2S

[CrO₂⁴⁻]=S

the relation between the solubility and the solubility product constant depends on the stoichiometry of the dissolution reaction

(2S)²(S)=4S³ = 8 * 10⁻¹²

S=∛ (2*10⁻¹²)

S= 1.26 * 10⁻⁴ M

2S = 2.52 * 10⁻⁴ M

Therefore the molar solubility in water of Ag₂CrO₄ is 2.52 * 10⁻⁴ M .
