12 G of carbon react with 16 G of oxygen how much carbon monoxide is formed ​
elena55 [62]

Answer:

28 g CO

Explanation:

First convert grams to moles.

1 mole C = 12.011 g (I'm just going to round to 12 for the sake of this problem)

12 g C • \frac{1 mol C}{12 g C} = 1 mol C

1 mol O = 15.996 g (I'm just going to round to 16)

16 g O • \frac{1 mol O}{16 g O} = 1 mol O

So the unbalanced equation is:

C + O_{2} -> CO (the oxygen has a 2 subscript because it is part of HONClBrIF meaning when not in a compound these elements appear in pairs - called diatomic elements)

The balanced equation is:

2 C + O_2 -> 2 CO

However, carbon is the limiting reactant in this equation and two moles cannot react because only 12 g (1 mole) are present. Therefore, use the equation

C + \frac{1}{2} O_2 -> CO.

1 mole of CO is formed, therefore 12 g + 16 g = 28 g CO.

Help pls do the last two all work and last two questions
andrew11 [14]

d1 = 15 miles

t1 = 1 hour

d2 = 25 miles

t2 = 2 hours

d = 15 + 25 = 40 miles

t = 1 + 2 = 3 hours

avg. \: speed \:  =  \:  \frac{total \: distance}{total \: time}

avg. \: speed \:  =  \frac{40}{3}

avg. \: speed \:  = 13.33mi \: hr ^{ - 1}
