Explanation:
Answer: 15 and 16
Explanation:
You can set up an equation N is one positive integer, and N+1 is the second (because they are consecutive, so it's the first number plus one).
Equation to solve for N
N(N+1) = N + (N+1) + 209
N^2 + N = 2N +1 + 209
N^2 - N - 210 = 0 (factor here)
N = 15 or N = -14
Since the question asks for the positive integers, you know the first number is 15, then the next would be 16.
Answer: C
Explanation: Option A uses data proving that people who live in poverty are led to shoplifting. Option B and D also does the same!
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.
