Answer:
2.67g of NH4Cl are required
Explanation:
Molarity is an unit of concentration in chemistry defined as the moles of solute (In this case, NH4Cl), per liter of solution.
To prepare 100mL of a 0.50M are required:
100mL = 0.100L * (0.50 moles / L) = 0.0500 moles NH4Cl
As molar mass of NH4Cl is 53.491g/mol:
0.0500 moles * (53.491g / mol) =
<h3>2.67g of NH4Cl are required</h3>
t can be transferred from one region to the other. In solids heat is transferred by a process called conduction. In vacuum heat transfer is by a process called radiation. In fluids (gases and liquids) heat is transferred by a process known as convection.
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.
I think both of them are but I really don't know
