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.
Hello! Rutherford’s gold foil experiment was actually really cool. While he put a beam of alpha particles into a sheet of gold foil, a few of those particles were easily deflected. He soon discovered that the reason those particles being deflected was because a little tiny nucleus. He was the one who found out the nuclear theory of an atom. I hope this was one of your answers. If not, feel free to message me and tell me your options. I’ll help you as much as I can. Have a great day! :)
Answer:
33.58%
Explanation:
Data obtained from the question include:
Mass of CuS = 9.56g
Mass of Cu = 6.35g
Mass of S = Mass of CuS — Mass and Cu
Mass of S = 9.56 — 6.35
Mass of S = 3.21g
The percentage by mass of sulphur in CuS is given by:
Mass of S/mass of CuS x 100
Percentage by mass of S = 3.21/9.56 x 100 = 33.58%
Answer:
Is when there is an increase in the temperature of the liquid
Explanation:
Increase in temperature of the liquid is an indication that chemical change occur because chemical change occur through process of chemical reaction and it involve when two or more substances combine together to form new substances which is as a result of change in chemical composition. The crystals dissolved in water to form another new solution and it became warm and this indicate a chemical change, new substances are formed as a result of increase in temperature.
