Hi I know I should know the answers to them, however i was really behind and im doing a lab final online and I was hoping someone could help, thank you! 

When you dissolve sugar in water, what happens? 
-All of the C-O and O-H bonds are broken 
-The forces between sugar molecules are broken 
-The forces between sugar molecules are broken and the the C-O and O-H bonds are also broken. 
-All the chemical bonds are broken 

For lab 4, we combined baking soda with vinegar, according to the chemical equationNaHCO3 + CH3COOH ==== NaCH3COO + CO2 + H2OConsider 3 experiments: (i) 2g baking soda + 5mL vinegar, (ii) 2g baking soda + 10mL vinegar and (iii) 2g baking soda + 20mL vinegar. The amount of CO2 produced was highest for (iii) and lowest for (i). For these experiments, which of the following is true? 
- Vinegar ran out first 
-Baking soda ran out first 
-They both ran out at the same time 
-Neither ran out 

If you add benzoic acid to a test tube that had water and toluene, the benzoic acid would dissolve in the toluene layer. If you add NaOH to the test tube, what will happen 
-A proton will be removed from benzoic acid and the resulting ion will dissolve in the water layer 
A proton will be removed from benzoic acid and the resulting ion will dissolve in the toluene layer 
-A proton will be added to benzoic acid and the resulting ion will dissolve in the water layer 
-A proton will be added to benzoic acid and the resulting ion will dissolve in the toluene layer 
-The layers will separate
