What grade is this? I forgot but if u tell me the grade i can prob remember
Answer:
AgNO2
Explanation:
The question asks to know which of these two insoluble salts is expected to be more soluble in acidic solution than in pure water.
To answer this question specifically, we need to know if the anions contained in the insoluble salt is a conjugate of a weak acid or that of a weak base.
Generally, the solubility of insoluble salts that contain anions which are conjugates of weak acids increases in the presence of an acidic solution than in water. While, the solubility of insoluble salts that contain anions which are conjugates of strong acids decreases in the presence of an acidic solution.
Having said this, AgNO2 contains NO2 which is the conjugate base of the Trioxonitrate iii acid which is a weak acid. Hence, it is expected to be stronger in acidic solution than in water.
The new volume of air trapper in the cylinder is determined as 116.56 mL.
<h3>
New volume of air in the cylinder</h3>
The volume of air trapper in the cylinder is determined from Boyle's law;
P₁V₁ = P₂V₂
where;
- P₁ is initial pressure = 1.08 atm
- V₁ is initial volume = 145.7 mL
- P₂ is new pressure = 1.25 x 1.08 atm = 1.35 atm
- V₂ is new volume = ?
V₂ = (P₁V₁)/P₂
V₂ = (1.08 x 145.7)/1.35
V₂ = 116.56 mL
Thus, the new volume of air trapper in the cylinder is determined as 116.56 mL.

#SPJ1
Answer:
1. Vegetable oil, which is a liquid at room temperature, is used in making cake batter. <u>Unsaturated</u>
2. Chocolate, which is solid at room temperature, is derived from a seed. <u>Saturated</u>
3. Butter<u>,</u> which is a solid at room temperature, is often used in cooking. <u>Saturated</u>
4. The oil inside flaxseed oil pills is liquid at room temperature. <u>Unsaturated</u>
Explanation:
Saturated fats are those kinds of fat that do not have a double bond between their carbon atoms when represented structurally. At room temperature, they tend to assume the solid-state, and they are mostly obtained from animal sources. Unsaturated fats do have a minimum of one double bond between their carbon atoms and tend to assume the liquid phase. They are mostly obtained from plant sources.<em> </em>
1. Vegetable oil is obtained from a plant source and is, therefore, unsaturated fat.
2. Chocolate even though it comes from cocoa is solid at room temperature and is mostly comprised of saturated fat.
3. Butter a solid at room temperature is mostly made up of saturated fat and is sourced from animals.
4. Flaxseed oil obtained from a plant source is mostly unsaturated fat.
