The 2 types of mechanical weathering are .....
1) * Temperature Change
-Temperature change makes rocks contract and expand
-Also one of the important cause of mechanical weathering.
2) * Abrasion
-Abrasion is a process in which an external force
Example: water movement or gravity which causes rock materials grind (reduce <<< synonyms) which can break apart the outer layers of affected rocks.*PLEASE GIVE THIS A THANKS :) :D xD AND ALSO THE BRAINIST ANSWER PREETTY PLEASEEEEEEEE, DON'T YOU EVER FEEL LIKE YOUR GOOOOING TO GIVE ME THE BRAINIEST ANSWER/CROWN??? xD

Answer:
chemical
Explanation:
Chemical weathering, which is the decomposition of a rock by the alteration of its chemical composition.
Answer:
Ethylene glycol
HOCH₂CH₂OH
Explanation:
For the molecules in the question, the viscosity will rise with the number of hydrogen bonds that can be formed.
A hydrogen bond is a week physical bond which is formed when hydrogen is found between atoms with high electronegativity (oxygen, nitrogen, fluorine):
O-H ··· O, N-H ··· O, N-H ··· O, O-H ··· N, F-H ··· F and so on.
Here we have have two compounds that can form hydrogen bonds (between themselves):
C) ethanol and D) ethylene glycol
Ethylene glycol have more hydroxide groups (-OH) than the ethanol so it will form more hydrogen bonds thus increasing its viscosity.
Answer is: 8568.71 of baking soda.
Balanced chemical reaction: H₂SO₄ + 2NaHCO₃ → Na₂SO₄ + 2CO₂ + 2H₂O.
V(H₂SO₄) = 17 L; volume of the sulfuric acid.
c(H₂SO₄) = 3.0 M, molarity of sulfuric acid.
n(H₂SO₄) = V(H₂SO₄) · c(H₂SO₄).
n(H₂SO₄) = 17 L · 3 mol/L.
n(H₂SO₄) = 51 mol; amount of sulfuric acid.
From balanced chemical reaction: n(H₂SO₄) : n(NaHCO₃) = 1 :2.
n(NaHCO₃) = 2 · 51 mol.
n(NaHCO₃) = 102 mol, amount of baking soda.
m(NaHCO₃) = n(NaHCO₃) · M(NaHCO₃).
m(NaHCO₃) = 102 mol · 84.007 g/mol.
m(NaHCO₃) = 8568.714 g; mass of baking soda.
