Answer:
the heat source must be greater than 100°C
the water must be permitted to evaporate quickly
the system must be sealed and become pressurized above atmospheric pressure
the vapor pressure must be kept below 760 mmHg
Explanation:
A superheated water is a dry form of steam in which hydrogen bonds that strongly binds the molecules of water has been overcome.
Superheated water finds application in a wide range of places. For example they are used for sterilization of clinical equipment.
- To produce steam or superheated water, the temperature of the source must be greater than the boiling temperature and less than the critical temperature at 374°C.
- Since superheated water is steam and steam is water in gaseous form. The water must be made to evaporate more quickly than it should condense back.
- High pressure and sealing the system helps to produce superheated water very fast.
- If the pressure between the vapor is kept low, water will boil faster.
Mass of Hydrogen gas required to react : 0.936 g

Reaction on Nitrogen gas and Hydrogen gas to produce Ammonia gas
N₂ (g) + 3 H₂ (g) ⇒ 2 NH₃ (g)
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol
so mol Nitrogen for 3.5 L at STP :

From the equation, mol ratio of N₂ : H₂ = 1 : 3, so mol H₂ :

then mass of Hydrogen(MW= 2 g/mol) :

Answer:
Radium is used to produce Radon
Explanation:
Radon is a gas used to treat cancer (certain types).
The mass of the aqueous solution in grams is obtained by subtracting mass of the 10.0 mL graduated cylinder alone from the mass of the cylinder + solution. Therefore mass of the solution is 2.951 g.
We have from the question, the following information;
Mass of empty 10.0 mL graduated cylinder to be 23.099 g
Mass of 10.0 mL graduated cylinder + 3.09 mL of solution to be 26.050g
Mass of aqueous solution in grams = mass of the cylinder + solution - mass of the 10.0 mL graduated cylinder alone
= 26.050g - 23.099 g
= 2.951 g
