Answer:
It needs an force in the opposite direction.
Explanation:
Example:
The box is on a flat surface. You use your hands to push it. You have to push it in the opposite direction.
Answer:
29.85°C
Explanation:
0°K is absolute zero. That is is same as -273.15°C.
To find C, subtract 273.15 from the temperature in °K.
303K - 273.15°C = <em><u>29.85°C</u></em>
The correct statements which are true for the reactions in the Sun are that are fusion reactions and reactions occur because of very high temperatures.
<h3>What is nuclear fusion?</h3>
Nuclear fusion reactions are those reactions in which two species reacts with each other for the formation of new specie.
In the core of the sun, nuclear fusion of hydrogen atoms occur for the formation of helium molecules in the presence of high temperature.
Hence, the correct statements are they are fusion reactions and reactions occur because of very high temperatures.

Answer:
Compound A: Propylbenzene
Compound B: Cumene
Explanation:
On this case, we have two clues:
<u>1) The mass spectrometry info</u>
<u>2) The formation of benzoic acid</u>
If we have the formation of benzoic acid with a strong oxidant (
). It means that we have an <u>alky group bonded to benzene</u>. Therefore we have to <u>add three carbons to a benzene</u> ring in order to obtain the mass of the compound (120).
The next question is <u>how these three additional carbons are bonded</u> to the benzene. For this, we have to check the mass info. For compound A we have a <u>fragmentation moeity on 91</u> therefore we have a <u>loss of an ethyl group</u>. Therefore compound A have a <u>linear structure</u> for the aditional three carbons.
For compound B we have a <u>fragmentation moeity on 105</u> this means a loss of 15 units of mass therefore we <u>loss a methyl grou</u>p. This indicates that we have a <u>non linear structure</u> fo the three additional carbons.
See figures 1 and 2.
I hope it helps!
20 I think that’s the volume of it because 50-70 is 20 so it must’ve been 20 volume that lifted the water to 70 ML
