C or A. I can’t decide tho. I know most def it’s gotta be one of them two.
the formula we is as follows:-
M1V1= M2V2
where
M1=1.2
V1=0.133l
V2=41l
M2=?
1.2 × 0.133 = 41 × M2
0.1596 = 41 × M2
M2 = 0.15960/41
M2 = 0.0038926829
When water (H2O) is added to liquid isopropanol to form a solution, then polar isopropanol molecules are attracted to polar water molecules at the surface of the water. It forms a solution of rubbing alcohol.
<h3>Isopropanol and water in the solution</h3>
Isopropyl alcohol is water-soluble and forms hydrogen bonds with molecules of water (H2O).
When H2O is added to liquid isopropanol to form a solution, H2O spread in a uniform way in the solution.
These isopropanol molecules can surround H2O molecules, which are carried into the solution.

Answer:
The added energy in the hot water causes water molecules to move faster and sucrose molecules to vibrate faster.
Explanation:
This added movement tends to make the bonds between sucrose molecules easier to overcome.
Hope it helps :-)
Answer:
The solid parts are the bones or the bone / cartilage tissue of the body, where they are composed of proteins such as: collagen type 1 approximately 80%, in addition 10% of other proteins combined with polysaccharides such as osteonectin and bone sialoprotein, or others proteinglucan or glycoproteins.
Explanation:
These proteins are proteins that make up the bone tissue structure, forming part of the extracellular matrix, providing consistency and support.
Type 1 collagen is one of the most important proteins in hard tissues, since it is one of the first to be formed by the osteoblast during osteoid formation, which will later calcify and conform to mature bone.
The synthesis of type 1 collagen fundamentally requires vitamin C, and it is also synthesized initially in a reticular way when the bone is immature, and then linearly when the bone becomes laminar or mature.
