Why ammonia is a identified as a weak base?

Chemistry
1 answer:
trapecia [35]3 years ago
7 0

Answer:

Ammonia doesn't contain any hydroxide ions to begin, but it's dissolved in water acquires hydrogen ion from the water to produce hydroxide as well as ammonium ions. However ammonia doesn't fully convert into hydroxide and ammonium ions in solution that's why ammonia is a weak base.

A helium balloon has a volume of 36 L. The pressure of the helium gas in the balloon is 132 kPa and its temperature is 27 degree
Verdich [7]

Answer:

n =1.905mol

Explanation:

Hello!

In this case, by considering helium gas as an ideal one, we can use the following equation:

PV=nRT

Whereas P should go in atmospheres and T in Kelvins; thus we proceed as follows:

n=\frac{PV}{RT}=\frac{132kPa*\frac{1atm}{101.325kPa}*36L}{0.08206\frac{atm*L}{mol*K}(27+273)K} =1.905mol

Best regards!

Write about the characteristics of carbon compounds:
mart [117]

The characteristics of carbon compounds are they exist with different structures in which the atoms are arranged differently and it forms more compounds than other elements combined.

Explanation:

The carbon atom has atomic number 6 which represents the number of electrons. It is represented by C and it is a non- metal. It has 6 protons, 6 neutrons, and 6 electrons. They are smaller in size so that it can fit in to larger molecules.

It is the only element that can form different compounds because each carbon atoms can form four chemical bonds to other atoms.

The structure of carbon atom is represented with its atomic number 6. The first two electrons are present in inner shell and the remaining four are present in the second shell.

The carbon combines with oxygen, hydrogen, and nitrogen to form many molecules for cellular function. Carbon and hydrogen combine to form hydrocarbon chains and rings.

For example the structural formula for Methane (CH4)

I can't figure this problem out, please help
mario62 [17]
First you have to look at the mole ratios of the reactants and products and that ratio is 2:2:2 or you can reduce that to 1:1:1.  That means an amount of peroxide will produce the same amount of oxygen gas.  If there are 8 mol of peroxide will give 8 mol of oxygen gas
