C = 0.11 mol
V = 5.65 L
n = ???
n = C*V
n = 0.11 * 5.65
n = 0.622 mols
1 mol of CaCl2 = 40 + 2*35.5 = 111 grams
0.622 mol = x
x = 111 * 0.622
x = 69.0 grams CaCl2
There is a couple different ways to determine if a bond is ionic orcovalent. By definition, an ionicbond is between a metal and a nonmetal, and a covalent bond is between 2 nonmetals. So you usually just look at the periodic table and determine whether your compound is made of a metal/nonmetal or is just 2 nonmetals.
1)They are all take up space.
2)They all have mass.
3)They are all solids.
Because of 1 and 2, they are all matter.

Inside the stomach, Hydrochloric acid kills micro-organisms in the food. Stomach juices begin to break down <u>proteins</u> to amino acids.
✤ So, Fill the blank with proteins.
<h3>
<u>Explanation:-</u></h3>
- Inside the stomach, the digestion of proteins starts due to the action of pepsin enzyme.
- But this enzyme remains inactive and is activated by the Hydrochloric acid(HCl).
- The Hydrochloric acid also helps in killing the germs and microbes which entered along with food.
- The mucous lines the wall of stomach to protect it from the harm caused by HCl because HCl is a strong acid.
- In stomach, The partial digestion of proteins occur and rest is digested in the small intestine by Trypsin(Pancreatic enzyme) and Intestinal juices.
