What name is given to bonds that involve the sharing of electrons? What name is given to bonds that involve the sharing of elect

Alina [70]

Answer:

Covalent bonds.

Explanation:

Covalent bonds are intermolecular bonds which involve the sharing of electrons between atoms or molecules and ions with close or near electronegativity values.

This usually form molecules. This is also the sharing of electrons donated by one of the atoms or by both of the atoms to form a molecule and at the same time obtain a stable octet state.

Identify the substance which has same number of molecules in 14g N2

valentina_108 [34]

We need to know the number of molecules which is number of moles * Avogadro’s number
So
We need to compare number of moles because Avogadro’s numbers is constant for all
We’ll start with Nitrogen gas : 14g/28g.mol=0.5 mole

For NH3 : 3.4g / (14+3)g.mol= 0.2 mol
For NO. : 15g/(14+16)g.mol = 0.5 mol
For O2 : 64g/32 g.mol = 2 mol
For SO2: 32g /( 32+32) g.mol = 0.5mol
For H2. : 1g/ 2g.mol = 0.5 mol

So
H2& SO2 & NO have the same number of moles of N2 and the same number of molecules of N2

Xcc of 5N HCL was diluted to 1 litre of normal solution calculate the value of x

Colt1911 [192]

Answer:

200cc of 5N HCl were diluted

Explanation:n

<em>Assuming the solution was diluted to prepare a 1N HCl solution:</em>

The HCl was diluted from 5N to 1N, that is a dilution of:

5N / 1N = 5 times

As the total volume of the diluted solution is 1L = 1000mL = 1000cc the amount of the concentrated solution was:

1000cc / 5 =
