Answer:
185 gms o NaBr
Explanation:
Na Br mole weight = 22.989 +79.904 = <u>102.893 gm/mole</u>
1.083 x 10^24 molecules / 6.022 x 10^23 molecules / mole = <u>1.798 moles</u>
102.893 * 1.798 = 185 gms
That statement is true.
Reason: If you are familiar with the cell theory, the cell theory states 3 things:
- All living things are made up of cells
- Cells are the basic unit of life
- Cell comes from other cells
Any living things are made up of cells- which is why cells are considered the building blocks of life on Earth.

Answer:
Hydrocyanic acid.
Explanation:
Hydrocyanic acid or hydrogen cyanide is also known as formonitrile (HCN), it is a colorless, extremely poisonous liquid (because it inhibits cellular oxidative processes) which is having boiling point 26 °C, freezing point -14 °C, and highly volatile in nature.
The solution of hydrogen cyanide in aqueous is known as Prussic acid or Hydrocyanic acid. Hydrogen cyanide is used for many chemical processes such as fumigation, the concentration of ores, the case-hardening of steel and iron.
