Answer:
46 g
Explanation:
The balanced equation of the reaction between O and NO is
2 NO + O₂ ⇔ 2 NO₂
Now, you need to find the limiting reagent. Find the moles of each reactant and divide the moles by the coefficient in the equation.
NO: (80 g)/(30.006 g/mol) = 2.666 mol
(2.666 mol)/2 = 1.333
O₂: (16 g)/(31.998 g/mol) = 0.500 mol
(0.500 mol)/1 = 0.500 mol
Since O₂ is smaller, this is the limiting reagent.
The amount of NO₂ produced will depend on the limiting reagent. You need to look at the equation to determine the ratio. For every mole of O₂ reacted, 2 moles of NO₂ are produced.
To find grams of NO₂ produced, multiply moles of O₂ by the ratio of NO₂ to O₂. Then, convert moles of NO₂ to find grams.
0.500 mol O₂ × (2 mol NO₂/1 mol O₂) = 1.000 mol NO₂
1.000 mol × 46.005 g/mol = 46.005 g
You will produce 46 g of NO₂.
The number of neutrons is the difference between the mass number and the number of protons.
You get the element by looking at the atomic number which is the number of protons. In this case, it is 9 and yes, it is F.
<span>However it is not an atom because it has 10 electrons so you have a fluoride ion F-. </span>
<span>The number of neutrons = 19 - 9 = 10
Therefore, the answer is D.

- The atomic mass of carbon is 12.011 g/mol.
- The atomic mass of hydrogen is 1.00794 g/mol.
This means the molar mass of CH is
Dividing the given molar mass by this,
This means the molecular formula is
When H is positive and S is negative
