Gaseous butane CH3CH22CH3 reacts with gaseous oxygen gas O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O. What is the theoretical yield of carbon dioxide formed from the reaction of 3.49g of butane and 17.1g of oxygen gas

Answers

Answer 1

Answer:

10.56 g

Explanation:

C4H10(g) + 13/2O2 (g) -------> 4CO2(g) + 5H2O(l)

Number of moles of butane = 3.49g/ 58 g/mol = 0.06 moles

1 mole butane yields 4 moles of CO2

0.06 moles of butane = 0.06 × 4/1 = 0.24 moles of CO2

Number of moles of oxygen = 17.1g/32g/mol = 0.53 moles of oxygen

6.5 moles of oxygen yields 4 moles of CO2

0.53 moles of oxygen yields 0.53 × 4/6.5 =0.33 moles of CO2

Butane is the limiting reactant

Theoretical yield of CO2 = 0.24 moles × 44g/mol = 10.56 g

Decide which element probably forms a compound with hydrogen that has a chemical formula most and least similar to the chemical formula of the compound formed by hydrogen and oxygen.

Answers

The question is incomplete, the complete question is shown in the image attached to this answer

Answer:

Most similar - sulphur

least similar- gallium

Explanation:

The compound formed when hydrogen reacts with oxygen is water. The chemical formula of water is H2O.

Water is very similar to H2S which is the compound formed when hydrogen reacts with sulphur. The bonds in water and H2S are both polar covalent bonds.

However, gallium is a metal and its hydride (GaH3) is least similar to water.

An empty Erlenmeyer flask weights 241.3 g. When filled with water (d = 1.00 g cmଷ ⁄ ), the flask and its contents weight 489.1 g. What is the flask’s volume? What is the mass of the flask when filled with chloroform (d = 1.48 g cmଷ ⁄ )?

Answers

Answer:

608 g

Explanation:

Mass of flask + contents = 489.1 g

Mass of flask = 241.3 g.

Mass of water = 489.1 - 241.3 = 247.8 g

Density of water = 1.0 g/cm^3

volume of water = 247.8 g/1.0 g/cm^3

Volume = 247.8 cm^3

But

Volume of flask = volume of water

Volume of flask = 247.8 cm^3

volume of chloroform = volume of flask

mass of chloroform = 1.48 g/cm^3× 247.8 cm^3

Mass of flask + chloroform = 366.7 g + 241.3 = 608 g

What rules should you follow when adding and subtracting? Check all that apply.

Answers

Answer:

The answer to this question would be:  

2. The exponents need to be the same so the leading numbers can be added or subtracted.

3. The result has the same number of decimal places as the least precise number.

The exponent is the 10^x that used in scientific notation. .When adding 12.3* 10^5 with 34.56 * 10^4, you need to make the exponent same first. In this case, it would become 12.3* 10^5 + 3.456 * 10^5= 15.756* 10^5

The decimal place could be rounded up to the least precise number. I'm not sure with the significant figures but it seems to use the biggest one.

Answer:

B) weathering and erosion

Explanation:

The two processes responsible for changing metamorphic and igneous rocks into sedimentary rocks is weathering and erosion.

Weathering is the defined as the physical disintegration and chemical decomposition of rocks to form sediments and soils.

Erosion is the removal of weathered materials from the surface of the earth.

The process of erosion and weathering serves to convert igneous and metamorphic rocks into sediments by which a sedimentary rock is formed.

The half-life of sodium-24 is 15 days. A laboratory technician measures out a 72 g sample. Approximately how many grams of sodium-24 would remain after 45 days?

Answers

Answer:

after 45 days 9 g left

Explanation:

Given data:

Half life Na-24 = 15 days

Mass of sample = 72 g

Mass remain after 45 days = ?

Solution:

Number of half lives passed:

Number of half lives = time elapsed / half life

Number of half lives = 45 days / 15 days

Number of half lives = 3

At time zero total amount = 72 g

After first half life = 72 g/ 2= 36 g

At 2nd half life = 36 g/2 = 18 g

At 3rd half life = 18 g/2 = 9 g

Thus after 45 days 9 g left.

Suppose a psychrometer reads 80°F for the dry bulb and 76°F for the wet bulb. What is the relative humidity?

Answers

Answer: 84%

Explanation:

Using the table attached, one can find out the Relative humidity.

Look at the intersection between the temperature on the dry bulb and the difference between the temperature on the dry and wet bulb.

Dry bulb temperature = 80°F

Wet bulb temperature = 76°F

Difference = 80 - 76 = 4°F

Relative humidity is therefore:

A sample of lead (Pb) has a volume of 5 cm3 and a mass of 56.5 g. What is
the density of lead?

Answers

Hey there!

The formula for density is d = m/v.

The mass of the sample is 56.5 g, and the volume of the sample is 5 cm³.

So, to plug these values into the equation, we have:

[tex]d=\frac{56.5}{5}[/tex]

Simplified, this is:

d = 11.3

The unit for this is g/cm³, or grams per cubic centimeter.

So, the density of lead is 11.3 g/cm³.

Hope this helps!

Answer:

11.3 g/cm³

Explanation:

Density of lead

= Mass / Volume

= (56.5 g) / (5 cm³)

= 11.3 g/cm³

Nitrogen-13 has a half-life of about 10 minutes. How much of a 320g sample of N-13 would remain after 40 minutes?

Answers

Answer:

The half-life of a radioisotope describes the amount of time it takes for said isotope to decay to one-half the original amount present in the sample.

Nitrogen-13, because it has a half-life of ten minutes, will experience two half-lives over the course of the twenty minute period. This means that 25% of the isotope will remain after this.

0.25 x 128mg = 32mg

32mg of Nitrogen-13 will remain after 20 minutes.

A compound is composed of only C, H, and O. The combustion of a 0.519-g sample of the compound yields 1.24 g of CO2 and 0.255 g of H2O. What is the empirical formula of the compound

Answers

Answer:

C4H4O

Explanation:

1.24 g x 1mol/(44)g = 0.03mol C;

Mass of C: 0.03mol x 12.g/1mol

= 0.36g of C

mol of H: 0.255g x 1mol /(18) x2= 0.028mol

Mass of H; = 0.028g × 1 of H

Mass of O: 0.519 g – (0.36g +0.028g)= 0.131g;

0.131g/16 =0.008 mol

Divide by the smallest number of moles;

0.028/0.008 mol = 3.5; 0.03/0.008 mol =3.75, 0.008 mol/0.008 mol =1
