If alcohol has a density of 0.84 g/ml, would it float or sink in a cup of water (density of 1.00 g/ml)?

Denser materials will always sink below less dense materials.

So in this case, the alcohol would float since it has a lower density.

Classify these substances as acidic, basic, or neutral: vinegar, baking soda, tomato juice, sugar. A) vinegar-acidic Baking soda
Gnesinka [82]

Answer:

A) vinegar-acidic Baking soda-basic Tomato juice-acidic Sugar-neutral.

Explanation:

Hello,

In this case, it is widely acknowledged that vinegar is a diluted and processed form of acetic acid which is of course acidic as well as tomato juice which has a pH of about 4.2. Baking soda, which is chemically known as sodium bicarbonate has a pH greater than 7, for that is reason it is basic. Finally, sugar, is known by its neutrality, for which its pH is about 7, for that reason it is neutral. In such a way, answer is A) vinegar-acidic Baking soda-basic Tomato juice-acidic Sugar-neutral.

Regards.

Consider the following reaction mechanism:
snow_lady [41]

Answer:

  • <em><u>Step 2 (the slow step).</u></em>

Explanation:

The rate-determining step is always the slow step of a mechanism.

That is so, because it is the slow step which limits the reaction.

Imaging that for assembling a toy you have process of three steps:

  • 1. order ten pieces, which you can do in 1 minute: meaning that you can order order the pieces for 60/1 = 60 toys in 1 hour.

  • 2. glue the pieces and hold the toy until the glue hardens, which takes 1 hour: meaning finishingh 1 toy in 1 hour.

  • 3. pack the toy, which takes 2 minutes: meaning that you can pack 60/2 = 30 toys in one hour.

The time to glue and hold one toy until the glue hardens determines that you can assemble 1 toy in 1 hour and not 60 toys or 30 toys.

Thus, the step that determines the rate at which the reaction happens is the slowest step: step 2.

When KCl dissolves in water:
34kurt

This dissociation occur because:

O had to bond with H due to the Hydrogen bonding rule, which will form OH~ (Hydroxide).

K is more attracted to Hydroxide than Cl, so it will depart Cl and bond with OH~.

that leaves a H and a Cl, which one has a positive charge and the other has a negative, so they will bond and form Hydrochloric Acid.
