There are 337.23 × 10²³ atoms in 4 moles of aluminum sulfite Al₂(SO₃)₃.
Explanation:
The questions ask how many atoms are in 4 moles of aluminum sulfite Al₂(SO₃)₃?
To answer this we use the Avogadro's number to devise the following reasoning:
if in 1 mole of Al₂(SO₃)₃ there are 14 × 6.022 × 10²³ atoms
then in 4 moles of Al₂(SO₃)₃ there are X atoms
X = (4 × 14 × 6.022 × 10²³) / 1 = 337.23 × 10²³ atoms

Answer:
D
Explanation:
The formula for calculating kinetic energy is 1/2mv^2, where m is the mass and v is the velocity or speed of the object. Since all of the balls have the same mass, the one with the highest speed or velocity will have the highest kinetic energy. Hope this helps!
Answer:
Arrhenius
H, H₃O⁺
OH, OH⁻
Explanation:
The earliest and simplest definition of acids and bases was suggested by <u>Arrhenius</u>. He/They defined an acid as a substance with <u>hydrogen</u> in its formula that dissociates in water to yield <u>H₃O⁺ </u>and a base as a substance with <u>OH</u> in its formula that dissociates in water to yield<u> OH⁻</u>.
Acid:
An acid is the substance that sour in taste and turns the color of litmus paper from blue to red.
pH of acid is less than seven.
Base:
An acid is the substance that bitter in taste and turns the color of litmus paper from red to blue.
The pH of base is 7-14.
Arrhenius gives the simplest definition of acid and base.
Arrhenius acid:
A substance that increase the concentration of hydronium ion in solution is called acid.
HNO₃ → H⁺ + NO₃⁻
(H₂O)
Arrhenius base:
A substance that increase the concentration of OH⁻ ion in solution is called base.
KOH → K⁺ + OH⁻

Answer:
Water has the unique ability to dissolve many polar and ionic substances. This is important to all living things because, as water travels through the water cycle, it takes many valuable nutrients along with it! Water has high heat capacity.
