Alpha decay lowers the atomic number of an element. The correct option is B. Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle, which is an helium particle. During this process, the atomic number of the nucleus is reduced by two and the mass number is reduced by 4.
Answer:
The oeriodic table have 8 groups
Answer:
The answer to your question is: Carboxylic acid.
Explanation:
Carboxylic acid: Carboxylic acids are organic acids that have the carboxylic group.
Carboxylic group is a carbon attach with a double bond to oxygen (C = 0), with a single bond to a hydroxyl group (C - OH) and with a single bond to a chain of carbons.
The general structure is shown below.
Answer:
Here's what I get
Explanation:
1. Water
The O-H bond in water is highly polar.
It has about one-third ionic character.
The partially-positive H atoms and partially negative O atoms strongly attract each other by hydrogen bonds.
It takes a large amount of energy to separate the water molecules from each other.
Thus, the boiling point of water is relatively high (100 °C).
2. Acetone
The C=O bond in acetone is much less polar.
It is less than 20 % ionic.
The dipole-dipole attractions in acetone are much weaker than the hydrogen bonds in water.
It takes much less energy to separate the acetone molecules from each other.
Thus, even though the molar mass of acetone is more than three times that of water, the boiling point of acetone is only 56 °C.
