Answer:
The shipping weight of one dining chair without the cushion is 10.8 lbs
Explanation:
First find the total weight of the cushions by multiplying the weight of the cushions by the amount of cushions:
2.4x8=19.2
Then, find the weight of chairs without cushions by subtracting the weight of the cushions from the total weight of the chairs with the cushions on it:
105.6-19.2=86.4
Finally, find how much one chair without a cushion weighs by dividing the total weight of the chairs without cushion by the amount of chairs:
86.4÷8=10.8
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.
