Answer:

1. NO2

2.49.4%

Explanation:

1. Find the moles of each and divide by the smallest

N: 30/14=2.14/2.14=1

O: 62/16=3.875/2.14=1.81 (round to nearest whole number)

NO2

2. Find the total mass and divide by each

Total: 291.7167

There are 9 oxygens so multiply mass by 9

16*9=144

144/291.7167=0.493629607

Predict the organic product formed when phosgene reacts with an excess of methanol.
gulaghasi [49]
When phosgene is reacted with an excess of methanol, this produces dimethyl carbonate. Dimethyl carbonate is used in methylating anilines, phenols, and carboxylic acids, and is also being studied for its use as an alternative additive in fuel.

The industrial production of dimethyl carbonate no longer uses phosgene because of the latter's toxicity. Phosgene widely gained infamy when it was used in chemical warfare during WWI.
