Answer:

limiting reactant started with/limiting reactant needed=

= 3.5 mol/3.5 mol=1:1

Explanation:

                                       2H2 +   1 O2 ---> 2 H2O

from reaction                 2 mol      1 mol

given                              3.5 mol    2.5 mol

needed                          3.5 mol    1.75 mol

Excess reactant O2, Limiting reactant H2.

Limiting reactant will be used completely.

So,  limiting reactant started with/limiting reactant needed=

= 3.5 mol/3.5 mol=1:1

Answer:

The arm that was not sprayed with anything

Explanation:

The control group would be <u>the arm that was not sprayed with anything</u>.

<em>The control group during an experiment is a group that forms the baseline for comparison in other to determine the effects of a treatment. The control group does not include the variable that is being tested and as such, it provides the benchmark to measure the effects of the tested variable on the other group - the experimental group. In this case, the experimental group would be the arm that was sprayed with the repellent.</em>

1. Describe the correlation between acid concentration and reaction rate and use ideas about particles to explain the correlatio
Nostrana [21]

Explanation:

an increase in concentration increases the rate of the reaction. This is because there are more reactant particles available which allows for more effective collisions between reactant particles in a given period of time. More effective collisions bring about a faster rate of reaction.
