Answer: Option (C) is the correct answer.
Explanation:
Chemical formula of a secondary amide is R'-CONH-R, where R and R' can be same of different alkyl or aryl groups. Here, the hydrogen atom of amide is attached to more electronegative oxygen atom of the C=O group.
Therefore, the hydrogen atom will be more strongly held by the electronegative oxygen atom. As a result, there will be strongly hydrogen bonded in the liquid phase of secondary amide.
Whereas chemical formula of nitriles is RCN, ester is RCOOR' and acid chlorides are RCOCl. As no hydrogen bonding occurs in any of these compounds because hydrogen atom is not being attached to an electronegative atom.
Thus, we can conclude that secondary amides are strongly hydrogen bonded in the liquid phase.
Answer:
The kinetic particle theory explains the properties of the different states of matter. The particles in solids, liquids and gases have different amounts of energy. They are arranged differently and move in different ways.

Answer:
The mass in grams of one mole of a substance.
1. 2NaN3 —> 2Na + 3N2
2. 2Pb + 2H2O + O2 —> 2Pb(OH)2
3. 2C4H12 + 13O2 —> 8CO2 + 10H2O
4. 4Fe + 3Sn(NO3)4 —> 4Fe(NO3)3 + 3Sn
5. Fe(NO3)3 + 3NaOH —> Fe(OH)3 + 3NaNO3
Balancing equations depends on the atom numbers you start with.
If you are having trouble you can look up ‘chemical equation balancer’ and type in the starting elements and simply replace the arrow with an = equal sign and then enter the reactants. It will show you the balanced equation
But please— make sure you actually understand the process of balancing because it’s important for future chem classes
