Explanation:
Answer:
A. to determine the efficiency of the reaction
Explanation:
Percentage is the ratio of the actual yield to theoretical yield as a percentage. It is calculated by dividing the actual yield by theoretical yield then multiplying by 100%.
Calculation of percentage yield is important as it helps in the determination of efficiency of a reaction. For example in most industries for the purpose of making the most product with the least waste.
Additionally, calculating the percentage yield helps in determining other products that may be formed during the reactions.
Answer:
Rows on the periodic table represents a period, which is the number of energy levels or rings. It is the last shell which valence electrons are on.
For example the first row waas Hydrogen and Helium which each have one energy level.
The esecond row has Carbon and Oxygen which has two energy level.
The third row has Sodium which has three energy levels and so on.
The simplest Organic compounds are made up of only Carbon and Hydrogenatoms only. Compounds of Carbon andHydrogen only are called Hydrocarbons. The simplest Hydrocarbon is methane, CH4.
Answer:
Reproduction may be asexual when one individual produces genetically identical offspring, or sexual when the genetic material from two individuals is combined to produce genetically diverse offspring.
