If the sun output of solar radiation increased by 20% how would this impact the temperature of earth's mantle
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

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.
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.
ASAP PLSSS!!!!! How many atoms of strontium are in a sample of 33.6 mol strontium?
1) 4.22 x 1023 atoms Sr
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.

How many milliliters of 0.100 M HClO4 solution are needed to neutralize 50.00 mL of 0.0832 M NaOH?
Answers
moles of NaOH = (0.0832 x 50 ) /1000= 4.16 x10^-3 moles
since the mole ratio of HClO4 to NaOH is 1:1 the moles of HClO4 is also 4.16 x 10^-3 moles
volume of HClO4 is therefore = moles/ molarity
that is 4.16 x 10^-3mol/ 0.167 mol/L= 0.0249L
multiply by 1000 to convert to ml
0.0249 x 1000= 24.9 ml
The milliliters of 0.100 M HClO4 solution are needed to neutralize 50.00 mL of 0.0832 M NaOH is 24.9 ml.
What is neutralization?Neutralization is defined as a chemical reaction in which an acid and a base quantitatively react with one another. Because it determines how acidic or basic a solution is, a solution's pH is crucial. The interaction of H+ ions and OH- ions produces water in a neutralization reaction, which occurs when an acid and a base react to form water and a salt.
Since the mole ratio of HClO4 to NaOH is 1:1, the moles of HClO4 are equal to 4.16 x 10-3 moles.
The moles of NaOH are equal to (0.0832 x 50) /1000.
Therefore, the volume of HClO4 is equal to the moles/molarity, which is 4.16 x 10-3mol/ 0.167 mol/L= 0.0249L.
This amount is then multiplied by 1000 to get ml: 0.0249 x 1000 = 24.9 ml.
Thus, the milliliters of 0.100 M HClO4 solution are needed to neutralize 50.00 mL of 0.0832 M NaOH is 24.9 ml.

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

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.
