You add 28 grams of carbon. You find the actual yield to be 181.2 grams of CO2. What is the percent yield of CO2?

Answers

Answer:

79.14%

Explanation:

Given the equation : 2Fe2O3 + 3C 4Fe + 3C02

The theoretical yield of CO2 ; is 102.6g

Actual yield = 81.2 gram

Percentage yield = (actual yield / theoretical yield) * 100%

Percentage yield = (81.2 / 102.6) * 100%

Percentage yield = 0.7914230 * 100%

Percentage yield = 79.14%

Hence, tbe percentage yield of CO2 is 79.14%

A 2.50 L sample of butane gas (C4H10), measured at 22.0
oC and 1.20 atm pressure, is combusted completely and
the carbon dioxide gas collected at the same pressure and
temperature. What volume of CO2 is produced?

Answers

Answer:

Same i guess hdjekfhkshfjfkr

The resultant volume of the carbon dioxide gas which is produced by the combustion of butane is 14.4L.

How do we calculate the moles of gas?

Moles of any gas will be calculated by using the ideal gas equation as:

PV = nRT, where according to qustion for butane gas

P = pressure = 1.20 atm

V = volume = 2.50L

n = moles = ?

R = universal gas constant = 0.082 L.atm / K.mol

T = temperature = 22 degree celsius = 295.15 K

On putting values we get

n = (1.20)(2.50) / (0.082)(295.15) = 0.124 moles

Given chemical equation is:

C₄H₁₀ + 13/2O₂ → 4CO₂ + 5H₂O

From the stoichiometry of the reaction, it is clear that,

1 mole of C₄H₁₀ = produces 4 moles of CO₂

0.124 mole of C₄H₁₀ = produces 4×0.124=0.496 moles of CO₂

Now we calculate the volume for the carbon dioxide gas at the given pressure and temperature as:

V = (0.496)(0.082)(295.15) / (1.20) = 14.4 L

Hence required volume of CO₂ is 14.4 L.

What is the mass in grams of 4.4 moles of the element tungesten, W?​

Answers

Answer:

806.96 g

Explanation:

From the question,

Using,

No. of mole = reacting mass/molar mass.

n = R.m/m.m....................... Equation 1

make R.m the subject of the equation

R.m = molar mass of tungsten × number of mole of tungsten.................. Equation 2

Given: number of mole of tungsten = 4.4 moles

Constant: Molar mass of tungsten = 183.8 g/mol

Substitute these values into equation 2

Therefore,

mass of tungsten = 4.4×183.4

mass of tungsten = 806.96 g

809.6g is your answer

Answer:

1 mole of tungsten =184 g

4.4 mole of tungsten =184×4.4=809.6g

A greenhouse is filled with air that cotains more carbon dixoide than normal air has. How might phothsyphness and plant growth be affeacted

Answers

Answer:

See explanation

Explanation:

We know that photosynthesis involves the combination of carbon dioxide and water in the presence of sunlight to yield glucose.

If the atmosphere is rich in carbon dioxide such as  in a green house where air is filled with carbon dioxide, the rate of photosynthesis is increased.

As the rate of photosynthesis is increased, the growth of plants is also increased.

Hence, in a greenhouse where the air contains more carbon dioxide, the rate of plant growth increases.

True or false: The phenolphthalein indicator changes colour close to the point of neutralization which shows the end-point of the titration.

Answers

Answer:

True

Explanation:

A titration can be defined as the experiment where the volume of known con concentration is mixed into another solution whose concentration is not known.

Most of the titration are acid-base titration. When performing titration the indicator which is used is usually phenolphthalein. The end point of the titration is the point where the indicator changes its color.

In case of acid base reaction, the end point is achieved when the phenolpthalein turns faint pink in color from transparent.

Hence, the given statement is correct, the indicator changes its color close to the end point of titration.
