When .080 moles of propane burn at STP, what volume of carbon dioxide is produced?
The answer is 5.4 L (I NEED THE STEPS)

Answers

Answer 1

Taking into account the reaction stoichiometry and the definition of STP, 5.4 L of carbon dioxide is produced.

Reaction stoichiometry

In first place, the balanced reaction is:

C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

C₃H₈: 1 mole O₂: 5 moles CO₂: 3 moles H₂O: 4 moles

Moles of CO₂ formed

The following rule of three can be applied: if by reaction stoichiometry 1 mole of C₃H₈ form 3 moles of CO₂, 0.080 moles of C₃H₈ form how many moles of CO₂?

[tex]amount of moles of CO_{2} =\frac{0.080 moles of C_{3} H_{8}x3 moles of CO_{2} }{1 mole of C_{3} H_{8} }[/tex]

amount of moles of CO₂= 0.24 moles

Definition of STP condition

The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.

Volume of CO₂ produced

You can apply the following rule of three: If by definition of STP 1 mole of CO₂ occupies 22.4 L, 0.24 moles of CO₂ how much volume does it occupy?

[tex]volume of CO_{2} =\frac{0.24 molesx22.4 L}{1 mole}[/tex]

volume of CO₂= 5.376 L ≅ 5.4 L

Finally, 5.4 L of carbon dioxide is produced.

A rubber ball is held 4.0 m above a concave spherical mirror with a radius of curvature of 1.5 m. At time equals zero, the ball is dropped from rest and falls along the principal axis of the mirror. How much time elapses before the ball and its image are at the same location?

Answers

The time elapsed when the ball placed above the concave mirror and the image formed would be at the same location is 0.55 s.

Image distance

The position of the image formed is determined using the followimg mirror formula;

[tex]\frac{1}{f} = \frac{1}{v} + \frac{1}{u}[/tex]

where;

f is the focal length of the mirrorv is the image distanceu is the object distance

f = R/2

f = 1.5/2

f = 0.75 m

When the ball and its image is in the same position, u = v

The position of the ball is calculated as;

[tex]\frac{1}{f} = \frac{1}{u} + \frac{1}{u} \\\\\frac{1}{f} = \frac{2}{u} \\\\u = 2f\\\\u = 2(0.75)\\\\u = 1.5 \ m[/tex]

Time of motion of the ball

The time taken for the ball to travel the caluclated distance is determined as;

h = ut + ¹/₂gt²

1.5 = 0  + ¹/₂(9.8)t²

1.5 = 4.9t²

t² = 1.5/4.9

t² = 0.306

t = 0.55 s

Thus, the time elapsed when the ball and its image are at the same location is 0.55 s.

Why are polar and non polar liquids immiscible?

Answers

Answer:

When both liquid molecules are polar then they can attract one another - which leads to mixing (miscibility).

When the molecular liquid is nonpolar, then the water molecules attract only one another while ignoring the nonpolar liquid. the result is that the two liquids are immiscible.

Explanation:

I hope it helps mark me brainliest^^

Answer:

They lack lack inter-molecular forces to disolve in the polar liquids.

Explanation:

Miscibility is the property of two substances to mix in all proportions (that is, to fully dissolve in each other at any concentration). Polar molecules like water will mix well with some other polar molecules but things like oil which are non polar do not mix well with polar molecules. This is because the oil and water lack inter-molecular forces to keep them mixed.

At constant pressure Thermal energy always moves from a greater energy level to a lesser energy level, laws of thermodynamics prove that.

Nature always likes to attain equilibrium either it's movement of heat energy or flow of water from higher region to lower region. The first and second law of thermodynamics are profe of that, the first law says that the total energy of universe is Constant. Energy can not be destroyed it always changes from one form to another, by work and heat. The second law explains why thermal energy moves from a greater energy level to a lesser energy level, it deals with the change in entropy of a system and surrounding and states heat flows from hot environment to cold environment.

How many grams are in 4.25 moles of NiS?

Answers

Answer:

386.75 grams

Explanation:

You can use dimensional analysis to help you solve for this question

1. set up a proportion

                          x grams

4.25 mol x        x mole

2. to find the amount of grams/mol that are in NiS we find the gram formula mass (mass of all the atomic masses of each element)

Ni- 59 grams

S- 32 grams

add these together and you get 91 g/mol

3. now plug in the values and multiply across

                    91 grams

4.25 mol x     1 mole

when you multiply across this is equal to 386.75 grams

How many moles of gas are present in the sample of gas occupies that 4.32 L at 1.45 atm pressure and -18oC? (Include your formula used and the set-up.)

Answers

The amount of gas present in the sample which occupied the given volume at the given pressure and temperature is 0.3mol.

Ideal Gas Law

The Ideal gas law states "that pressure multiplied by volume is equal to moles multiply by the universal gas constant multiply by temperature of gas. It is expressed;

[tex]PV = nRT[/tex]

Where P is pressure, V is volume, n is the amount of substance, T is temperature and R is the ideal gas constant( [tex]R = 0.08206 Latm/molK[/tex]

Given the data in the question;

Volume; [tex]V = 4.32L[/tex]

Pressure; [tex]P = 1.45atm[/tex]

Temperature; [tex]T = -18^oC = 255.15K[/tex]

Amount of gas; [tex]n =\ ?[/tex]

To determine the moles of gas, we substitute our given values into the expression above.

[tex]PV = nRT\\\\1.45atm * 4.32L = n * 0.08206Latm/molK * 255.15K\\\\6.264Latm = n * 20.937609Latm/mol\\\\n = \frac{6.264Latm}{20.937609Latm/mol} \\\\n = 0.3mol[/tex]

Therefore, the amount of gas present in the sample which occupied the given volume at the given pressure and temperature is 0.3mol.
