What kind of intermolecular forces act between a hydrogen cyanide (HCN) molecule and a carbon monoxide molecule?
Dahasolnce [82]

Answer:

Dispersion forces

Dipole-Dipole interaction

Explanation:

The London dispersion force refers to the temporary attractive force that acts between the electrons in two adjacent atoms when the atoms develop temporary dipoles. Dispersion forces act between any two molecules even when other intermolecular forces are in operation as long as the molecules are in close proximity to each other.

Now, CO is polar and the HCN is also polar molecule. Hence, dipole - dipole interaction forces  are also in operation and acts between the two molecules in close proximity to each other.

Which of the following is not a true statement?
Lilit [14]

Answer: 3.42 moles CO = 84.0g, is not true.

Explanation:

Moles is given by the formular; Mass / Molar Mass.

Therefore; 0.2 moles O2 = 6g is true  when we multiply 32g x 0.2 = 6g approximately.

 0.75 moles H2CO3 = 47g.

Molar formular for H2CO3 = 2 + 12 + 48 =62g.

If we multiply  62g (molar mass ) by 0.75moles, it gives us 47g approximately.

3.42 moles CO = 84g

molar mass of CO = 12 + 16 = 28g

Multiply 28g x 3.42 moles =  95.76g, which is not true.

Write a balanced equation and ka expression for the bronsted-lowry acid hcooh in water
statuscvo [17]
The given acid is HCOOH, it is dissociated in water. This balanced equation represents the dissociation of HCOOH in water:

HCOOH + H2O ---> H+ + COOH-

The Ka of HCOOH is:

Ka = concentration of products / concentration of reactants

Ka = [COOH-] [H+] / [HCOOH]
