Chemistry..help!?

I-Cl , H-Br , H-F

Look at the difference of electronegativities

First stability the equation. Do H first, then double it, by way of fact the O is provided in instruments of two. Then do N. final, do O2. Then make a ratio between the NH3 and O2, utilising the coefficients from the balanced equation to 34.8 L NH3. Then do a ratio between the NH3 and O2, utilising the coefficients from the balanced equation, to 40.0 L O2. certainly one of the two ratios will teach the two NH3 or O2 to be in extra; the single that's no longer in extra is the proscribing reagent. Use the proscribing reagent to be sure the variety of liters of NO produced. considering one mole of a gas, at STP, occupies 22.4L, be sure the variety of moles of NO. Then convert to grams. you additionally can try this by potential of looking the variety of moles given of each and every of the reacting gases, discover the proscribing reagent, use the balanced equation to discover moles of NO, then convert to grams. yet i think the 1st way will use what you're actually utilising in college.
