Answer:

4.76 mol / L

Explanation:

The process that takes place is:

Sc₂(C₂O₄)₃ → 2Sc⁺³ + 3C₂O₄⁻²

Assuming we have 1 L of the solution, we would have 2.38 moles of Sc₂(C₂O₄)₃.

We then convert 2.38 moles of Sc₂(C₂O₄)₃ into moles of Sc⁺³, using the stoichiometric coefficients:

2.38 mol Sc₂(C₂O₄)₃ * [tex]\frac{2molSc^{+3}}{1molSc_2(C_2O_4)_3}[/tex] = 4.76 mol Sc⁺³

Finally we calculate the concentration of scandium ion (Sc⁺³) in mol/L:

4.76 mol Sc⁺³ / 1 L = 4.76 mol/L

What is IUPAC Nomenclature?

The IUPAC system of nomenclature is a set of logical rules framed which are mainly aimed at giving an unambiguous name to an organic compound.

IUPAC stands for International Union of Pure and Applied Chemistry

A prefix to the name comes before the molecule. The prefix of the molecule's name is based on the number of carbon atoms.

For example, a chain of six carbon atoms would be named using the prefix hex-.

The suffix to the name is an ending that is applied that describes the types of chemical bonds in the molecule.

Therefore, The prefix indicates a molecule with 2 carbon atoms is eth- and the correct option is option A.

If you add 25.0 mL of water to 125 mL of a 0.150 M LiOH solution, what will be the molarity of the resulting diluted solution? 0.0450 M LiOH 0.0647 M LiOH 0.125 M LiOH 0.134 M LiOH

Answers

Answer:

solute in a fixed volume of solution

Concentration(c) = number of moles of solute(n) / volume of solution (v)

25.0 mL of water is added to 125 mL of a 0.150 M LiOH solution and solution becomes more diluted.

original solution molarity - 0.150 M

number of moles of LiOH in 1 L - 0.150 mol

number of LiOH moles in 0.125 L - 0.150 mol/ L x 0.125 L = 0.01875 mol

when 25.0 mL is added the number of moles of LiOH will remain constant but volume of the solution increases

new volume - 125 mL + 25 mL = 150 mL

therefore new molarity is

c = 0.01875 mol / 0.150 L = 0.125 M

answer is 0.125 M

A scientist formulates the following hypothesis: If plants of the same species
are grown under the same conditions, the amount of fertilizer the plants
receive will affect their growth rate. Which variable will be a responding
variable in the experiment designed to test this hypothesis?

Answers

Answer:

Growth rate

Explanation:

The responding variable, also known as the DEPENDENT VARIABLE, is the variable that responds to changes or manipulations made to another variable (independent or manipulable variable) in the experiment. It is the measured variable of an experiment.

According to the hypothesis provided for this investigation, the scientist wants to determine if the amount of fertilizer plants of the same species receive will affect their growth rate when planted in the same condition. This shows that the independent variable is the amount of fertilizer to be used while the RESPONDING VARIABLE OR DEPENDENT VARIABLE is the GROWTH RATE OF THE PLANTS because it responds to the amount of fertilizer.

The question is incomplete, the complete question is;

The half-life of strontium-90 is about 29 years. How many half-lives have elapsed when 6.25% of a strontium- 90 sample remains in the container?

Answer:

4 half lives

Explanation:

From;

N/No = (1/2)^t/t1/2

N= amount of strontium-90 present at time t

No= amount of strontium-90 originally present

t= time taken

t1/2 = half life of strontium-90

But N= 0.0625No

Hence;

0.0625No/No = (1/2)^t/29

0.0625 = (1/2)^t/29

(1/2)^4 = (1/2)^t/29

4 = t/29

t = 4 × 29

t= 116 years

Hence four half lives have elapsed

At the midpoint of a titration curve ________. At the midpoint of a titration curve ________. The concentration of a conjugate base is twice that of the concentration of a conjugate acid The pH equals the pKa The ability of the solution to buffer is at its least effective The concentration of a conjugate base is 1/2 that of the concentration of a conjugate acid

Answers

Answer:

The concentration of a conjugate base is twice that of the concentration of a conjugate acid

Explanation:

This is because at the midpoint, the number of moles of acid equals half the number of moles of base at the midpoint. This means that at the midpoint, half the analyte has been titrated.

Since the concentration of the conjugate acid is half that of the conjugate base at the midpoint, this implies that the concentration of the conjugate base is twice that of the conjugate acid.

Thus, at the midpoint of a titration curve the concentration of a conjugate base is twice that of the concentration of a conjugate acid
