The answer is hydroxides.
The elements of the group IA are termed as alkali metals, because their hydroxides are alkaline.
The answer is; They each have the same number of protons
All uranium isotopes have 92 protons in their nucleus. However, they differ in the number of neutrons in the nucleus, hence this also translates to varying mass numbers (which is the sum of neutrons and protons in the nucleus). The most common isotopes of uranium are; U-238, U-235, and U-234.
Answer: Option (b) is the correct answer.
Explanation:
According to the law of conservation of mass, mass of a substance can neither be created nor it can be destroyed but it can simply be transformed from one form to another.
Therefore, when a metal is burned in a closed container, the mass of the container and its contents do not change because they follows law of conservation of mass.
Thus, we can conclude that when a metal is burned in a closed container, the mass of the container and its contents do not change then it is a law.
Sometimes, it depends.
