.- 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)
Answers
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

bri is doing her schoolwork in a room that is 10 feet. Since it's the end of the year, we've decided to fill this room with 3'' diameter plastic balls to a depth of 3 feet. Estimate the number of balls needed to fill her "office" space. To keep things consistent, round the volume of the plastic ball to the nearest thousandths.
Answers
An estimate of the number of balls needed to fill Bri's office space is approximately 28,846 balls.
To estimate the number of balls needed to fill Bri's office space, we need to calculate the volume of the plastic balls and then divide the volume of the room by the volume of each ball.
First, let's calculate the volume of a 3" diameter plastic ball. The diameter is 3", which means the radius is half of that, so the radius is 3/2 = 1.5". To convert the radius to feet, we divide by 12 (since there are 12 inches in a foot): 1.5"/12 = 0.125 feet.
The volume of a sphere is given by the formula V = (4/3)πr³, where r is the radius. Plugging in the radius, we have V = (4/3)π(0.125)³ ≈ 0.0104 cubic feet (rounded to four decimal places).
Next, we calculate the volume of the room. The room has a length, width, and depth of 10 feet. The volume of a rectangular prism is given by V = length x width x depth, so the volume of the room is V = 10 x 10 x 3 = 300 cubic feet.
Finally, we divide the volume of the room by the volume of each ball to estimate the number of balls needed:
300 cubic feet / 0.0104 cubic feet ≈ 28,846 balls (rounded to the nearest whole number).

The equation of a circle with radius r and center at the origin (0,0) and radius 3 cm is x²+ y² = 9.
The graph is given below.
What is a circle?A circle is a two-dimensional figure with a radius and circumference of 2πr.
The area of a circle is πr².
The equation of a circle is (x - h)² + (y - k)² = r²
Where (h, k) is the center of the circle.
We have,
The equation of a circle with radius r and center at the origin (0,0).
x²+ y² = r²
Now,
If the radius of the circle is given, we can substitute the value of r into the equation and simplify it to obtain the final equation.
For example:
If the radius of the circle is 3 cm, the equation of the circle is:
x²+ y² = 3²
x²+ y² = 9
This equation represents all the points in the plane that are exactly 3 units away from the origin.
The circle with a radius of 3 cm is graphically represented below.
Thus,
The equation of a circle with radius r and center at the origin (0,0) and radius 3 cm is x²+ y² = 9.

Answers
The solution to the system of equations is x = 2 and y = 1.
First, let's manipulate each equation into slope-intercept form (y = mx + b):
3x - 2y - 10 = 0
-2y = -3x + 10
y = (3/2)x - 5
x + 2y - 14 = 0
2y = -x + 14
y = (-1/2)x + 7
Next, we can plot the two lines on a graph by finding their y-intercepts and slopes:
Line 1: y = (3/2)x - 5
y-intercept: -5
slope: 3/2
To plot this line, we can start at the y-intercept of -5 and then use the slope to find additional points. For example, we can go up 3 units and over 2 units to get the point (2, 1).
Line 2: y = (-1/2)x + 7
y-intercept: 7
slope: -1/2
To plot this line, we can start at the y-intercept of 7 and then use the slope to find additional points. For example, we can go down 1 unit and over 2 units to get the point (2, 6).
Now, we can graph the two lines on the same coordinate plane:
```
|
8 -| .
-| .
6 -| .
-|.
4 -|
-|
2 -| .
-| .
0 -|_____________
0 2 4 6 8
```
From the graph, we can see that the two lines intersect at the point (2, 1). Therefore, the solution to the system of equations is x = 2 and y = 1.
We can verify this solution algebraically by substituting x = 2 and y = 1 into both equations and verifying that they are both true:
3x - 2y - 10 = 0
3(2) - 2(1) - 10 = 0
6 - 2 - 10 = 0
0 = 0 (true)
x + 2y - 14 = 0
2 + 2(1) - 14 = 0
4 - 14 = 0
-10 = 0 (false)
Since the second equation is false when x = 2 and y = 1, this means that (2, 1) is not a solution to that equation alone, but it is a solution to the system as a whole. Therefore, our solution is correct.

Answers
Answer:
The balance in 2020 is $47,810,662.65576
Step-by-step explanation:
In order to find the balance in 2020, first we would have to calculate the number of year as follows:
number of years, t=2020-1626
number of years, t=394
Therefore, to calculate the balance in 2020, we would have to use the following formula:
f(t)= 24(1.0375)∧394
f(t)=24*1,992,110.94399

Find and graph the number of ounces of water, x, that Will could have put in each cup.
Answers
According to the information, we can infer that the number of ounces of water, x, that Will could have put in each cup is 8 ounces.
What is the number of ounces of water "x" that Will could have put in each cup?Will initially had a cooler filled with 144 ounces of water. After using 16 ounces to fill his water bottle, there were 144 - 16 = 128 ounces of water remaining in the cooler.
Will then took out 16 plastic cups for his teammates. Since the same amount of water was put in each cup, the remaining amount of water, 128 ounces, needs to be divided equally among the cups.
Dividing 128 ounces by 16 cups gives us 8 ounces of water for each cup.
So, Will could have put 8 ounces of water in each cup.

Fraction
14 / 20
7 / 10
(just simplify 14/10 by dividing by 2 on the numerator and demotinator.)
14 out of 20 can be written as the fraction 7/10 and as the percentage 70%.
To write 14 out of 20 as a fraction, we can simply write it as a ratio of 14 to 20.
Fraction: 14/20
However, this fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 2.
Dividing 14 by 2, we get 7, and dividing 20 by 2, we get 10.
So, the simplified fraction is:
7/10
To express this fraction as a percentage, we can convert it by multiplying it by 100.
Percentage: (7/10) x 100 = 70%
Therefore, 14 out of 20 can be written as the fraction 7/10 and as the percentage 70%.

Answers
The mean arterial pressure formula is MAP = CO x TPR or MAP = (SBP + 2DBP) / 3.
The mean arterial pressure (MAP) formula is:
MAP = CO x TPR
where:
CO is the cardiac output (how much blood is siphoned by the heart each moment)
TPR is the all-out peripheral resistance (the resistance from the bloodstream in the body's veins)
On the other hand, the mean arterial pressure can also be calculated using the following equation:
MAP = (SBP + 2DBP)/3
where:
SBP is the systolic blood pressure (the highest pressure in the arteries when the heart beats)
DBP is the diastolic blood pressure(the lowest pressure in the arteries when the heart is at rest between beats)
