Answer:
Explanation:
Given that:
The heat of combustion of methylhydrazine =
It means that:
1 mole of methylhydrazine on combustion, releases of energy
Molar mass of methylhydrazine = 46.072 g/mol
Means that, 1 mole of methylhydrazine contains 46.072 g of methylhydrazine
Thus,
46.072 g of methylhydrazine on combustion, releases of energy
Also,
1 g of methylhydrazine on combustion, releases of energy
206.2 g of methylhydrazine on combustion, releases of energy
Heat released =
Answer:
The chloride ion has no effect on the acidity of the solution since HCl is a strong acid. Chloride is a very weak base and will not accept a proton to a measurable extent. However, the ammonium ion, the conjugate acid of ammonia, reacts with water and increases the hydronium ion concentration:
Explanation:
Explanation:
According to ideal gas equation, product of pressure and volume equals the product of number of moles, gas constant and temperature.
Mathematically, PV = nRT
where P = pressure, V = volume
n = no. of moles, R = gas constant = 0.0821 atm L/mol
T = temperature
Since, it is known that number of moles equal mass divided by molar mass.
Hence, number of moles of given sample of acetone are as follows.
No. of moles =
=
= mole
Therefore, putting the values in ideal gas equation as follows.
PV = nRT
= 0.359 atm
In 1 atm equal to 760 mm Hg. So, convert 0.359 atm into mm Hg as follows.
= 272.84 mm Hg
Hence, pressure of the ideal gas will be 100 mm Hg + 272.84 mm Hg = 372.84 mm Hg
Thus, we can conclude that the ideal gas pressure in the container if all of the liquid acetone evaporated is 372.84 mm Hg.
