What is the % yield of CO2 if 10g of CO produces 12.8 g CO2?
2CO + O2 → 2CO2

Answers

Moles CO = 10.0 g / 28.01 g/mol = 0.357
the ratio between CO and CO2 is 2 : 2 ( or 1 : 1) so we would get 0.357 mole of CO2 ( 100% yield)

mass CO2 = 0.357 mol x 44.0098 g/mol = 15.7 g ( theoretical yield)

% yield = 12.8 x 100 / 15.7 = 81.5

Hope this helps.

The % yield is 81.5 :DDDDDD

A 3.0 M HCl(aq) solution contains a total of(1) 3.0 grams of HCl per liter of water
(2) 3.0 grams of HCl per mole of solution
(3) 3.0 moles of HCl per liter of solution
(4) 3.0 moles of HCl per mole of water

Answers

Answer : The correct option is, (3) 3.0 moles of HCl per liter of solution

Explanation :

Molarity : It is defined as the number of moles of solute present in one liter of the solution. The S.I unit of molarity is mole per liter.

It is represented as,

$Molarity=\frac{\text{Moles of solute}}{V_(solution)(L)}$

where,

V = volume of solution in liter

As we are given 3.0 M HCl(aq) solution this means that 3.0 moles of HCl present in one liter of solution.

Hence, a 3.0 M HCl(aq) solution contains a total of 3.0 moles of HCl per liter of solution.

Molarity = number of moles / volume in liters solution

Suppose you have designed a new thermometer called the x thermometer. On the x scale the boiling point of water is 129 ?x and the freezing point of water is 13 ?x. Part a at what temperature are the readings on the fahrenheit and x thermometers the same?

Answers

(x1,y1) (x2,y2)

(32,15) (212,135)

y = mx + b

m=(y2-y1)/(x2-x1)

m=.66667

y = .66667*(x) + b

Plug in #s to test for b value

15 = .66667*(32) + b

b = -6.334

y = mx + b

y = .6667*(x) + (-6.334)

F = .6667*(F) + (-6.334)

F = (.6667*(F) = -6.334

(F - .6667F) = -6.334

F(1 - .6667) = -6.334

F = -19

ThermX = F @ -19 degrees
