This problem is providing the initial volume and pressure of nitrogen in a piston-cylinder system and asks for the final pressure it will have when the volume increases. At the end, the answer turns out to be 2.90 atm.
<h3>Boyle's law</h3>
In chemistry, gas laws are used so as to understand the volume-pressure-temperature-moles behavior in ideal gases and relate different pairs of variables.
In this case, we focus on the Boyle's law as an inversely proportional relationship between both pressure and volume at constant both temperature and moles:
Thus, we solve for the final pressure by dividing both sides by V2:
Hence, we plug in both the initial pressure and volume and final volume in order to calculate the final pressure:

Answer:
Explanation:
The unbalanced nuclear equation is
It is convenient to replace the question by an atomic symbol, 
, where <em>x </em>= the atomic number, <em>y</em> = the mass number, and Z = the symbol of the element.
Then your equation becomes
The main point to remember in balancing nuclear equations is that the <em>sums of the superscripts and of the subscripts</em> must be the same on each side of the equation.
Then
93 – 1 = <em>x</em>, so <em>x</em> = 92
232 + 0 = <em>y</em>, so <em>y</em> = 232
Element 92 is uranium, so the nuclear equation becomes
Answer:
A
C
Explanation:
For the reaction of m-bromonitrobenzene from benzene first, we need to carry out the nitration of benzene utilizing HNO3, H2SO4.
Bromination of nitrobenzene with Br2, FeBr3 outfits m-bromonitrobenzene in light of the fact that nitro group is meta coordinating for electrophile. The mechanism activity for the reaction is shown in the image below.
H3O4 is your answer but u should use your chart
<u>Answer:</u>
<em>The material we are talking about would be serpentine.</em>
<u>Explanation:</u>
This material is available in two colours green or white and it has a hardness that amounts to 2.5. This material has a luster that is nonmetallic and more of waxy in nature.
This feature becomes Satiny when Nature of is material is Fibrous. This material is used as an insulating material against electricity as well as heat. The property of this mineral is very close to asbestos and is used when prevention from heat and electricity is required.
