Explanation:
4. limestone heat lime + carbon dioxide
The reactants in this expression above is limestone
The products of the reaction is carbon dioxide and lime
Reactant is the species that gives the product and it is usually found on the left hand side of the expression.
The product is the substance on the right hand side of the expression that forms through the experiment.
Heat is used to facilitate the reaction.
5. An exothermic reaction is a reaction in which heat is given off.
An endothermic reaction is a reaction in which heat is absorbed in the process.
An exothermic reaction is always warmer after the reaction whereas an endothermic reaction is colder at the end of the reaction.
Answer:
I needed to use good precision in my measurement for my chemistry lab
Explanation:
Answer:
c tarnishes in air
Explanation:
After silver has been exposed to air that contains sulphur gases, discoloration would occur. there would be darkening that is caused by the reaction with gases.When any silver object tarnishes, it brings about a disfiguring of that object. Hydrogen sulphide would be needed for this to happen. silver sulphide is black and a if a thin layer should form on any surface, it ill darken it. This is what we refer to as tarnishing.
Answer:
The correct option is: Cost of materials used in manufacture
Explanation:
There are two types of costs of an object: the internal costs and the external costs.
The internal cost of an object is the direct monetized cost. It refers to the cost involved in the <u>production or manufacturing of a given objec</u>t. Example: labor, <u>material required</u>, equipment, energy, and overhead expenses.
Water can be understood as both yin and yang. The number of ways Yin and Yang can be explained is in numerous ways.
Yin and Yang explain how to exist in harmony and in balance with nature. Yin and Yang are not distinct entities, but rather two extremes of a spectrum. Everything Yin includes a trace of Yang. Also, everything Yang contains a trace of Yin. They are always in connection with one another.
The yin is the physical aspect of nature and the yang is the forces surrounding these physical aspects.
Some of the ways in which Yin and Yang can be explained are as follows:
- Yin and Yang can be explained from the water, whereby the water is the Yin while the wind carrying the water waves is known as the Yang.
- In the body, the Yin shows the anatomy and structure of the body while the Yang explains the psychological functioning of the body.
Disruption in either Yin or Yang can cause an imbalance in nature.
Therefore, we can conclude that the number of ways in which we can explain the Yin and the Yang is numerous.
