Answer:
The answer to your question is below
Explanation:
This student is wrong.
Chemical bonds are forces that hold atoms together to form a molecule or compound. These interactions are inside the molecule. Example
Ionic bond: NaCl (sodium and chlorine).
Intermolecular forces are weaker than chemical bonds and they are forces between atoms or molecules. These interactions are among different molecules.
Example
Two molecules of water interact forming hydrogen bridges.
Answer: 72 grams of 
are needed to completely burn 19.7 g 
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number 
of particles.
To calculate the number of moles, we use the equation:
Putting in the values we get:
According to stoichiometry:
1 mole of 
requires 5 moles of oxygen
0.45 moles of require= 
moles of oxygen
Mass of 
72 grams of are needed to completely burn 19.7 g
Answer:
0.158L
Explanation:
From the question, we obtained the following information:
C1 = 6.84 M
V1 =?
C2 = 1.84 M
V2 = 588 mL = 588/1000 = 0.588L
Using the dilution formula C1V1 = C2V2. The original volume can calculated for as follows:
C1V1 = C2V2
6.84 x V1 = 1.84 x 0.588
Divide both side by 6.84
V1 =(1.84 x 0.588) / 6.84
V1 = 0.158L
