What is measured by the reaction rate? the probability that a reaction will occur the speed at which products form the time requ
Cloud [144]

Answer: the speed at which products form

Explanation:

Rate of a reaction is defined as the speed at which a chemical reaction proceeds. It is often expressed in terms of the concentration of a reactant that is consumed in a unit time or the concentration of a product that is formed in a unit of time.

For a general reaction :A\rightarrow B

Rate=-\frac{d[A]}{dt}

or Rate=+\frac{d[B]}{dt}

where d[A] = change in concentration of reactant A

d[B] = change in concentration of product B

dt = time interval

The density of rubbing alcohol is 0.785g/mL at 25℃.
DochEvi [55]

Answer: The temperature is there to confuse you on purpose. Density changes with temp, but in these type of problems, they mean nothing

Explanation:

The formula for density is mass per unit of volume.

D=m/v

We dont have to do any conversions here so it boils down to division and multiplication.

0.785g/mL=mass/15mL\\0.785g/mL*15mL = mass\\=11.78 grams

Now for the second part:

0.785g/mL=15g/volume\\15g/0.785g/mL = volume\\=19.11mL

Answer:

C

Explanation:

Please see the attached picture for the explanation.

<u>Le Châtelier's principle</u><u>:</u>

When a stress is applied to a system at equilibrium, the system will respond by shifting in the direction that opposes/ minimizes the effect of the stress.

• This stress could be the addition or removal of a product or reactant, changes in the concentration of the products or reactants, or a change in temperature.

☆ Why can heat be written on the same side of the products when the reaction is exothermic?

• Exothermic means that heat is released, thus heat can be treated as a product.

• I like to remember it as Exothermic → Exit
