There are three factors in which natural selection occurs. Select one statement from the list below that is a true statement about natural selection.

Answers

Answer: There is no list in your question. But the three factors in which natural selection occurs are:

1. A struggle for existence,

2. Variation and

3. Inheritance

Explanation:

Darwin’s theory of natural selection is the way in which organisms change overtime.

These changes allow organisms to become better adapted to their environment and increase their chances for survival.

The three major factors through which natural selection occurs are:

1. A struggle for existence,

2. Variation and

3. Inheritance

Darwin’s theory of natural selection will occur if the three conditions above are met and unless these factors are in place, natural selection will not occur.

Which of the following setups will correctly convert 36.45 grams of sodium to moles of sodium?

Answers

Answer:

D.

Explanation:

To convert from grams of a substance to moles of a substance, you use molar mass as a conversion factor. Sodium's molar mass is 22.99 grams per mole. To cancel out grams, you need to place grams on the bottom and moles on the top.

A water solution containing an unknown quantity of a

nonelectrolyte solute is found to have a freezing point of

–0.23°C. What is the molal concentration of the solution?​

Answers

Answer:

The molal concentration of the solution is approximately 0.124 molal

Explanation:

The given parameters are;

The reduced freezing point of the water = -0.23°C

For freezing point depression of a solution, we have;

[tex]\Delta T_f[/tex] = [tex]K_f[/tex]· b·i

Where;

[tex]\Delta T_f[/tex] = The freezing point depression

[tex]K_f[/tex] = Cyroscopic constant (The freezing-point depression constant) = 1.86° Cm⁻¹ for water

b = The molality of the solution

i = van't Hoff factor = 1

Therefore;

[tex]\Delta T_f[/tex] = [tex]T^{\circ}_f - T_f[/tex]

Where;

[tex]T^{\circ}_f[/tex] = The freezing point of pure water = 0°C

[tex]T_f[/tex] = The freezing point of the solution = -0.23°C

∴ [tex]\Delta T_f[/tex] = [tex]T^{\circ}_f - T_f[/tex] = 0°C - (-0.23°C) = 0.23 °C

From, [tex]\Delta T_f[/tex] = [tex]K_f[/tex]· b·i, we have;

0.23°C = 1.86°C/m × b × 1

∴ b  = (0.23°C/1.86°C/m) ≈ 0.124 molal

Therefore, the molal concentration of the solution, b ≈ 0.124 molal.

Calculating pH
See chart below

Answers

Answer:

12, basic, 9, basic

Explanation:

pH = -log[H+]

Using the data in the table, you can calculate the pH:

-log[1e-12] = 12

-log[1e-9] = 9

To find out whether it is acidic, basic, or neutral, use a pH scale. Anything less than 7 is acidic, anything over is basic. Knowing this, both will be basic.

Mm 2mCOO 19. Calculate the hydrogen-ion concentration [H+] for the aqueous solution in which [OH-] is 1 x (3 points) 10-11 mol/L. Is this solution acididc, basic, or neutral? Show your work.

Answers

Answer: The hydrogen-ion concentration for the aqueous solution is [tex]10^{-3}mol/L[/tex] and solution is acidic.

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration and pOH is calculated by taking negative logarithm of hydroxyl ion concentration.  

[tex]pOH=-\log [OH^-][/tex]  

Putting in the values:

[tex]pOH=-\log[1\times 10^{-11}][/tex]

[tex]pOH=11[/tex]

[tex]pH+pOH=14[/tex]

\[tex]pH=14-11=3[/tex]

[tex]pH=-log[H^+][/tex]

[tex]3=-log[H^+][/tex]

[tex][H^+]=10^{-3}M[/tex]

As pH is less than 7, the solution is acidic.

How many grams of AgCl are produced from 10.0 g AgNO3?

Answers

Answer:

Equation of Reaction = AgNO3 (aq) + NaCl (aq) → AgCl (s) + NaNO3 (aq)

Steps:

1. Find the moles of AgNO3 with formula n= Mass/Mr (molecular mass)

so you will get moles= 10.0/ 169.87 = 0.05886854654

2. Using stoichiometry you know the equation has 1 mole so the moles of AgCl are gonna be the same; therefore, you will use again the same formula.

3.  moles= mass/molecular mass

0.05886854654 = x/ 143.32

You rearrange the formula to find the mass

so mass = moles x molecular mass

mass = 0.05886854654 x 143.32

mass= 8.44 grams

Answers

Answer:

The temperature will not be affected directly

Explanation:

The solar radiation has a direct effect on the outer surface and inner part of the earth but  an increase by 20% of the solar radiation will not cause the temperature of the Earth's mantle to increase because the factors that heat up the Earth's mantle are : Friction between core materials that sink into the center of the planet and Heat from decay of radioactive materials

2) 4.22 x 1024 atoms Sr


3) 2.02 x 1025 atoms Sr


4) 2.02 x1023 atoms Sr

Answers

Answer:

33.6 mol of the atom strontium contains approximately

3) 2.02 × 10²⁵ atoms of strontium

Explanation:

The number of atoms in one mole of a substance is given by Avogadro's number number, [tex]N_A[/tex], which is presented as follows;

1 mole of a substance contains [tex]N_A[/tex] = 6.022 × 10²³ elementary particles

33.6 mol of a substance will contain 33.6 × 6.02214 × 10²³ elementary particles of the substance

Therefore;

33.6 mol of the atom strontium contains 33.6 × 6.02214 × 10²³ = 2.023439 × 10²⁵ atoms of strontium

33.6 mol of the atom strontium contains ≈ 2.02 × 10²⁵ atoms of Sr.
