Answer:
They both have a reflection, but a mirror just reflects anything in front of it, while a magnifying glass helps you see closer through the reflection of something.
Explanation:
The given reaction is an exothermic reaction due to the negative amount of enthalpy. In this case, an increase in temperature favors the backward reaction which points to the creation of more products. The expression of K or Q is products over reactants concentration. When this happens, Q becomes smaller then. Hence answer is C and 1.
Using the graph, which describes how Henry ran the 100m race;
a) It takes Henry 20seconds to run 100m
b) Henry's average speed over the race is; 5m/s.
According to the linear graph which describes the distance ran by Henry during the 100m race as a function of time.
a) Since the distance from start ran by Henry is plotted on the vertical axis, and the time is plotted on the horizontal axis;
To determine how long it took Henry to run 100m; The point corresponding to 100m is traced downward from the line of the graph and we find out that;
It takes Henry 20seconds to run 100m
b) Henry's average speed over the race is simply;
The slope of the distance-time graph.
Therefore,
- Average speed = (100-0)/(20-0)
Therefore, Henry's average speed over the race is; 5m/s.

A change in the physical properties like mass or texture will not cause any change in the substance because the composition of the substance will retain the same.
<u>Explanation:</u>
A change of the physical properties will affect only the size, shape and structure of the compound, it won't be affecting the composition of the compound. Since any kind of change in the physical properties of the compound will only affect the outermost structure of the compound or the size of the compound.
It will not change the bond structure and neither it will break any bonds, thus the substance will be as it is. So, there will be no change in the substance on changing the physical properties like mass or texture, as the composition and bonding in the substance will retain the same.
I would go with c due the fact that water has tendencies to flow, meaning it will runoff and majority of the water will run off, it couldn’t be a because the fact that the grass and plant will absorb what they need. D clearly is too vague for such a question. B would be the only contesting answer but I feel c is the stronger choice because evaporations is a longer process and because of that only little amounts of water will evaporate while majority of it will become runoff due to hills, mountains, storm drains, slopes, etc.
