The number of molecules of NO₂ that can be obtained when 2 molecules of NO react is 2 molecules
<h3>Balanced equation</h3>
We'll begin by writing the balanced equation for the reaction. This is given below:
NO + O₂ —> NO₂
There are 3 atoms of O on the left side and 2 atoms on the right side. It can be balanced by writing 2 before NO and NO₂ as shown below
2NO + O₂ —> 2NO₂
Now, the equation is balanced
From the balanced equation above,
We can see that 2 molecules of NO will react to produce 2 molecules of NO₂.
Thus, we can conclude that 2 molecules of NO₂ will be obtained from the reaction.

The premium that the insurance company should charge each year to realize an average profit of $500 is $6,900.
First step is to calculated the expected amount to pay
Expected amount=Total loss +50% loss+25% loss
Expected amount=$200,000(0.002)(1)+$200,000(0.01)(0.5)+$200,000(0.1)(0.25)
Expected amount=$400+$1,000+$5,000
Expected amount=$6,400
Second step is to calculate the premium
Premium=Expected amount+ Average profit
Premium=$6,400+$500
Premium=$6,900
Inconclusion the premium that the insurance company should charge each year to realize an average profit of $500 is $6,900.

Answer:
9/5
Explanation:
original fraction : x/y
new fraction = .9x/(.5y)
= 9x/5y
(9x/5y) / (x/y)
= 9x/5y * y/x
= 9/5
= 1.8
so it increased by 80%
e.g suppose we had 100/200 or 1/2
new fraction = 90/100 or 9/10
new ratio = (9/10) / (1/2)
= 9/5
