When we increase the surface area of an object, more atoms are exposed. Since more atoms are exposed, the atoms can react faster, and this is why the rate of a reaction increases when the surface area increases.
For example, lets say we want to heat a potato. If we just put the whole potato in the microwave, it will take a long time for the potato to get thoroughly heated. However, if we chop the potato into smaller pieces, we will observe that it gets heated much faster. This is because we increased the surface area of the potato, which resulted in more potato atoms to be exposed to the heat, and caused the reaction to be faster.

<em>Mr. Clark is prescribed 500 mg of acetaminophen TID and 30 ml of prednisone BID. Mr. Clark takes his first dose of both medications at 0800 hours. [ You would administer the second dose of acetaminophen at 1400 hours. ]</em>
Hello!
<span>Carbonic acid is referred to as volatile acid because it is produced from a gas that evaporates quickly.
Volatility is the likeliness of a substance to vaporize. That is the tendency of the substance to pass to the gaseous phase. That means that these substances have a high vapor pressure. Coming from a gas, Carbonic Acid has a high tendency to pass to the vapor phase.
Have a nice day!</span>
Answer:
A
Explanation:
Of the main group elements, fluorine has the highest electronegativity (EN = 4.0) and cesium the lowest (EN = 0.79). This indicates that fluorine has a high tendency to gain electrons from other elements with lower electronegativities. We can use these values to predict what happens when certain elements combine.
Answer:
The physical and chemical properties of elements are periodic function of their atomic weights. This is Mendeleev's periodic law.
63 elements were classified by Mendeleev.
