<u>Answer:</u> The correct option is C) decomposition
<u>Explanation:</u>
Single displacement reaction is defined as the reaction where a more reactive element displaces a less reactive element from its salt solution.
Element B is more reactive than element A
Double displacement reaction is defined as the reaction where an exchange of ions takes place in a solution
Decomposition reaction is defined as the reaction where a single large chemical species breaks down into two or more smaller chemical species.
Synthesis reaction is defined as the reaction where two or more smaller chemical species combine together in their elemental state to form a single large chemical species.
For the given chemical reaction:
Here, water is breaking down into two smaller species of oxygen and hydrogen gas. Thus, it is a decomposition reaction.
Hence, the correct option is C) decomposition
Answer is: 12 grams of the isotope carbon-12 (¹²C).
The Avogadro’s number is the number of atoms in 12 grams of the isotope carbon-12 (¹²C).
Na is Avogadro number or Avogadro constant (the number of particles, in this example carbon, that are contained in the amount of substance given by one mole).
The Avogadro number has value 6.022·10²³ 1/mol in the International System of Units; Na = 6.022·10²³ 1/mol.
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.
Weathering and erosion produce smaller rock particles which, when mixed with dust result in different types of soil.
