Answer is: synthesis.
Synthesis reaction is a type of reaction in which multiple reactants (in this example several colors of modeling clay) combine to form a single product (a sculpture of a horse).
For example, synthesis chemical reaction: Ba + F₂ → BaF₂.
New substance, barium fluoride is formed, with different chemical and physical properties than reactants (barium and fluorine).
In barium fluoride, barium has oxidation number +2 and fluorine has oxidation number -1, so compound has neutral charge.
When Hexane is mixed with Water it forms a immiscible mixture. The two solvents does't make a uniform solution and create two layers.
Explanation:
Hexane is chain of six carbon atoms attached to carbon and hydrogen atoms. The molecule of hexane is non polar in nature. While water molecule is polar in nature. As LIKE DISSOLVES LIKE, so the hexane solvent being hydrophobic in nature fails to interact with hydrophilic water molecules.
The density of water is 1 g/cm³, it is heavier than Hexane with 0.66 g/cm³, so water will make the bottom layer while hexane will float on water forming the upper layer.
The correct option is D.
Engineers and constructions workers have different types of footwear, which they make use of when they are in the field. Each of these foot wears has its own purpose and functions. For instance, the steel toe boots serve to protect the foot from falling falling objects and also from compression. The foot wear has a protective support in the toe and also possesses a mid sole plate to protect the foot again puncture from the sole.
Answer: b) a chemical reaction between carbohydrates and oxygen to produce carbon dioxide, water, and heat energy
Explanation:
Based on the options, I assume that this is talking about the process of respiration. Respiration allows living things to produce energy by reacting carbohydrates with oxygen.
This results in the release of energy in the form of heat in a cell and also the formation of carbon dioxide and water. This type of respiration is known as Aerobic respiration.
