.- Sí 159.6 gramos de Fe2O3 liberan 67.2 litros de CO2 ¿cuántos litros de CO2 se liberan si reaccionan 45 gramos de Fe2O3? de acuerdo a la siguiente reacción: Fe2O3 (s) + 3 CO (g) 2 Fe (s) + 3 CO2 (g)
Answer:
45 g de oxido de hierro (III) liberarán 18.9 L de CO₂
Step-by-step explanation:
La reaccion quimica es la siguiente:
Fe₂O₃ (s) + 3CO (g) → 2Fe (s) + 3CO₂ (g)
1 mol de oxido de hierro (III), reacciona con 3 moles de monoxido de carbono para liberar 3 moles de CO₂ y 2 moles de Fe sólido.
Pasamos la masa de F₂O₃ a moles:
159.6 g . 1 mol /159.7g = 1 mol de oxido
Entonces, aplicamos la regla de tres:
1 mol de oxido produce 3 moles de dioxido de carbono, indudablemente eso será lo que formemos de producto, por lo tanto 3 moles de CO₂ estan ocupando 67.2 litros.
Ahora calculamos los nuevos moles:
45g . 1 mol /159.7 g = 0.282 moles
Aplicamos la regla de tres:
Si un mol de oxido produce 3 moles de CO₂
0.282 moles producen (0.82 . 3 ) = 0.845 moles de CO₂
Como tenemos menos moles de gas, el volumen ocupado sera mayor, hacemos la regla de tres:
Si 3 moles de CO₂ ocupan 67.2 litros
0.845 moles ocuparan (0.845 . 67.2/ 3 ) = 18.9 litros

T-shirts that usually sell for $28.99 are on sale
for $17.39. What percent off are they?
Answer: i think it is 46.38 %
Step-by-step explanation: add both numbers ( decimals) and just put the percentage. hope this will help u stay safe :)
Answer:
38.3%
Step-by-step explanation:
We have two equations to find the answer.
1. Discount = OG Price * Discount by 100%
2. Final Price = OG Price - Discount
So fill in the first equation :
Discount = 28.99 * 38.3/100
Discount = 28.99 * 0.38
Saved = $11.10
Now for the second equation :
Final Price = 28.99 - 11.10317
Final Price = $17.89
Therefore the discount is 38.3%
2 litres of lemonade costs £2.60. Find the cost of 6 litres of lemonade
Answer:
£7.80
Step-by-step explanation:
Since you multiply 2 by 3 to get 6, we are going to multiply 2.6 by 3
2.6 x 3 = 7.8
Thus the cost of 6 litres of lemonade is £7.80

(16/25)-3/2 help me solve
Answer:
-43/50
(decimal) = -0.86
Step-by-step explanation:
Find the LCD which is 50.
16/25 will be multiplied by 2 (because 25 x 2 = 50) so it will then equal 32/50
3/2 will be multiplied by 25 (2 x 25 = 50) = 75/50
subtract them which will give you -43/50

l--------------------------------------------------------------------------------------------l
Answer:
17= Prime number
54= Composite
77=Composite
23=Prime
Hello there!
Prime numbers have 2 factors and composite numbers have 3 or more factors.
17 is prime because it has only 2 factors: 1 and itself.
54 is composite because it has more than 3 factors.
77 is composite because it has more than 3 factors.
23 is prime because it has only 2 factors.
Hope this helps you!

y = 2x – 1
how do you graph this linear equation???
Answer:
You can choose x as any value like x = 7
if x were to equal 7 then
the equation would be y = 2 times 7 - 1
2 times 7 = 14 and 14-1 = 13
y would be 13 ifi x was 7
so you can graph the point 7,13

The polar form of the given complex number is:
[tex]W = \sqrt{12}* e^{-i*0.52}[/tex]
How to get the polar form of the complex number?
Here we have:
W = -3 + √3i
To get the polar form we first need the module of W it is:
|W| = √( (-3)^2 + (√3)^2) = √12
And now we need to find the bearing, that is given by the Arctangent of the quotient between the imaginary part and the real part.
Arctan(√3/-3) = -0.52 rad
Then the polar form is:
[tex]W = |W|*e^{-i*0.52} = \sqrt{12}* e^{-i*0.52}[/tex]
