Answer:
I think you are correct with your answer.
Explanation:
But I don't think that the explanation is correct because I think that it is the formation of both baking soda and water that makes it work...Vinegar doesn't make gas bubbles maybe because it hasn't reacted or maybe because it is not the right ingredient for the solution you are looking for. Thank you for the question.....Am not sure I really helped in your question but thank you..
405 PHz
I might be wrong because that might be for 0.74 nm. We will see with out people answers
Answer:
Chemical reactivity increases down a group and decreases from left to right of a period.
Explanation:
The higher the ionization energy is, the lower the reactivity is. Since the ionization energy is highest in the top right corner of the periodic table, we can assume that the most reactive elements are in the opposite bottom left corner. This is because the electrons that react are farther away from the nucleus thus experience less attraction to the nucleus (called nuclear shielding). Therefore their electrons are more easily removed than elements that don't ecperience nuclear shielding.
Answer: Freezing point of a solution will be 
Explanation:
Depression in freezing point is given by:

= Depression in freezing point
i= vant hoff factor = 1 (for non electrolyte)
= freezing point constant = 
m= molality

Weight of solvent (benzene)= 1480 g =1.48 kg
Molar mass of solute (octane) = 114.0 g/mol
Mass of solute (octane) = 220 g



Thus the freezing point of a solution will be 
1/32
Explanation it stated with half on 8 days then that means you divide 24 and 8 so its 3 and you have to multiply ✖ ½
