Answer:
- <u><em>g) Neither plant should increase by 1 cm in height.</em></u>
Explanation:
See the graph for this question on the figure attached.
The growing of the <em>plant A</em> is represented by the line that goes above the other. At start, that line has a slope that rises about 0.75 cm ( height increase) in 1 day. From the day 2 and forward the slope of the line decreases. The line reaches its highest point about at day 4 and seems to start decreasing. Thus, you should predict that on the day six it <em>most likely </em>does not increase in height.
The growing of the <em>plant B</em> is represented by the line drawn below the other. As for the plant B, the growing decreases with the number of days. Between the days 4 and 5 the line is almost flat, which means that <em>most likely</em> this plant will not grow on the day six or grow less than 0.5 cm.
Thus, for both plants you can say that <em>on day six, most likley, neither should increase by 1 cm in height (</em>option g).
The required pressure of the gas is 546 mmHg.
<h3>What is the relation between volume and pressure?</h3>
Relation between the volume and pressure of gas is explained through the ideal gas equation PV = nRT, and for the question required equation is:
P₁V₁ = P₂V₂, where
P₁ & V₁ are the initial pressure and volume.
P₂ & V₂ are the final pressure and volume.
On putting values from the question to the equation, we get
P₂ = (780)(350) / (500) =
P₂ = 546 mmHg
Hence required pressure is 546 mmHg.

For combustion reaction we need oxygen and the results most of the time produce heat which mean first one is correct.
Answer:
Explanation:
Chemical Reactions
1. The rate of a chemical reaction is affected by some factors such as: pressure, temperature, surface area e.t.c
2. Chemical reactions do not involve in changes with regard to the nuclei but in the reorganization of electrons.
3. Isotopes of an element in a chemical reaction behave in a similar manner.
Nuclear Reactions.
1. Nuclear reactions involves a change with respect to the nucleus of an atom, resulting in the production of a different element.
2. The rates of a nuclear reaction are not affected by external factors such as : temperature, pressure, catalyst e. t. c, but are usually spontaneous.
3. Large amount of energy usually accompany nuclear reactions.
