Answer: If a reaction produces a gas such as oxygen or carbon dioxide, there are two ways to measure the reaction rate: using a gas syringe to measure the gas produced, or calculating the reduction in the mass of the reaction solution.

Answer:
₈₈Ra²²⁶ → ₈₆Rn²²² + ₂He⁴ + energy
Explanation:
Alpha beta and gamma radiations are the examples of ionizing radiations.
Alpha radiations are emitted as a result of radioactive decay. The atom emit the alpha particles having two proton and two neutrons. It is also called helium nuclei. When atom undergoes the alpha emission the original atom convert into the atom having mass number less than 4 and atomic number less than 2 as compared to parent atom.
For example:
₈₈Ra²²⁶ → ₈₆Rn²²² + ₂He⁴ + energy
Properties of alpha radiation:
Alpha radiations can travel in a short distance.
These radiations can not penetrate into the skin or clothes.
These radiations can be harmful for the human if these are inhaled.
These radiations can be stopped by a piece of paper.
Another example:
₉₂U²³⁸ → ₉₀Th²³⁴ + ₂He⁴ + energy
Answer :C) through transferring or sharing electrons
Answer:
The answer is C: has at least three oxidation states.

Answer:
Chromatography is used to separate mixtures of substances into their components.They all have a stationary phase (a solid, or a liquid supported on a solid)
Explanation:
it's where the things stay still until the mobile phase moves through and takes the components
