Answer:
D. Two reactants combine to form one product
Explanation:
The definition of synthesis in chemistry is "the production of chemical compounds by reaction from simpler materials."
A is decomposition, B is DOUBLE replacement, and C is SINGLE replacement.
Answer:
See explanation below
Explanation:
In this case we have the starting reactant which is the ethine, In the first step reacts with NaNH₂, a strong base. This base will substract the hydrogen from one of the carbon of the ethine, and form a carbanion. This will react with the propane bromide, displacing the bromine and forming a 5 carbon chain with the triple bond on the carbon 1 and 2.
In the second step, reacts with the lindlar catalyst to do a reduction, and form a double bond between carbon 1 and 2. In essence, compound A is similar to compound B.
Finally B reacts with water in acid and makes a addition reaction, and form an alcohol.
The whole process can be seen in the picture below.
Hope this helps
Answer:
Average atomic mass = 6.6575.
Explanation:
As fractions the abundance is 1/4 and 3/4.
The average atomic mass = (5.03 + 3(7.20) / 4
= 6.6575.

Answer:
Both of them are polluting the environment. Industrial pollution is the pollution caused from industries and it can be in different forms such as water waster or air pollution. Agricultural pollution is caused from plants or crops that are grown by the farmers. For example, pesticides that may ruin the soil and is dangerous for our environment.
