The vultures would eventually decrease also because the vultures feed off the dead gazelles
Explanation:
As per the measurements that are made by the student are as follows.
21.6 cm is equivalent to 8.5 inch
Therefore, 1 cm for the given situation will be equivalent to inch as follows.
1 cm = inch
= 0.393 inch
Hence, we will calculate the ratio of cm : inch as follows.
Ratio of cm : inch =
= 0.39
Thus, we can conclude that the ratio of cm/inch using the students data is 0.39.
Answer:
As temperature increases, molecules gain energy and move faster and faster. Therefore, the greater the temperature, the higher the probability that molecules will be moving with the necessary activation energy for a reaction to occur upon collision.

Answer:
The student conclude that the sample of benzoic acid is impure.
Explanation:
The observed melting point of benzoic acid when a student melts his/her sample is low than the actual value. The reason for this might be:
(a) <u>The most probable reason is that the sample is impure. Impurities in the sample leads to lowering the value of the melting point.</u> The reason for the phenomenon is that when impurity is present in the compound, the pattern of the crystal lattice disturbs and thus it less amount of heat is require to break the lattice.
(b) There may be some experimental errors like:
- Non-uniform heating of the sample
- The sample is not tightly filled in the capillary if the student is following Kjeldahl's flask method.
- If the student is using melting point machine, there there might be some instrumental errors.
<u>The student conclude that the sample is impure.</u>
