Answer:
74.6 g
Explanation:
The computation of the number of grams produced at the time when 32.0 grams of C react is shown below:
As we know that
But before that we need to find out the moles of c i.e carbon which is
= 2.66 mol
As we know that
1 mol of C produces 1 mol of CO
So, for 2.66 mol, the mass of CO is
= 74.6 g
Basically we applied the above equation so that we can reach to the answer
Answer : Hydrogen-bonding, Dipole-dipole attraction and London-dispersion force.
Explanation :
The given molecule is .
Three types of inter-molecular forces are present in this molecule which are Hydrogen-bonding, Dipole-dipole attraction and London-dispersion force.
- Hydrogen-bonding : when the partial positive end of hydrogen is bonded with the partial negative end of another molecule like, oxygen, nitrogen, etc.
- Dipole-dipole attraction : When the partial positively charged part of the molecule is interact with the partial negatively charged part of the molecule. For example : In case of HCl.
- London-dispersion force : This force is present in all type of molecule whether it is a polar or non-polar, ionic or covalent. For example : In case of Br-Br , F-F, etc
Hydrogen-bonding is present between the oxygen and hydrogen molecule.
Dipole-dipole forces is present between the carbon and oxygen molecule.
London-dispersion forces is present between the carbon and carbon molecule.
