How many moles of O2will be produced from 6.2 moles of water?​

Answers

Answer 1

Answer:

I hope This will help you....and please mark me as Brilliant

Explanation:

The formula, H2O tels us that there are the same number of moles of Oxygen as there are of water. The (understood )molecular coefficient of H2O is 1. The (understood ) coefficient of O in the formula is also 1. The number of moles of oxygen is the same as the number of moles of water. This is moles of oxygen atoms. If the question wants moles of oxygen gas, O2, then it will be half as many I think that is what they want, so I would answer 3.1 moles of O2.

how does wind energy combined with machines cause a sailboat to move?

marking as brainliest

Answers

Answer:

The wind pushes the sails from behind, causing the boat to move forward.

Answer:

Wind energy obtained by the machine is converted into kinetic energy as it functions and thus enabling the boat to move.

Together, the forces of drag, from the water, and the pressure from the wind against the sail itself push the craft forward. Angling too sharply into the wind causes the forces on the boat to become unbalanced, and moves the boat sideways in the water.

Is neon an atom or ion

Answers

The neon atom, a noble gas, has a completely filled valence shell with an octet of electrons. It cannot become an anion by accepting another electron.
Neon has a very high ionization energy of 2080 kJ/mole, and in this respect it is second only to helium. Hence, forming a cation by losing an electron is an extremely difficult task for it.

Answers

Answer:

The steps in order are;

1. Obtain a 50-mL volumetric flask

2. Add approximately 10 mL of deionized water to the empty flask

3. Use a pipet to add the appropriate volume of stock solution to the flask

4. Cap the flask and invert several times to mix

5. Fill the volumetric flask with deionized water until the meniscus touches the mark

6. Swirl the flask to mix the contents

The volume of the acetic acid to be added to the solution is 15 mL

Explanation:

The given steps are;

4. Cap the flask and invert several times to mix

5. Fill the volumetric flask with deionized water until the meniscus touches the mark

6. Swirl the flask to mix the contents

1. Obtain a 50-mL volumetric flask

3. Use a pipet to add the appropriate volume of stock solution to the flask

2. Add approximately 10 mL of deionized water to the empty flask

The given parameters are;

The volume of the volumetric flask = 50-mL

The concentration of the final solution of acetic acid = 0.6 mg/L

The concentration of the stock solution = 2.0 mg/L

Let 'x' represent the volume of the stock solution added, we have;

2.0 mg/L·x + (50 - x)×0 = 0.6 mg/L × 50-mL

x = 0.6 mg/L × 50-mL/(2.0 mg/L) = 15 mL

The volume of the stock solution to be added, x = 15 mL

Gaseous ethane CH3CH3 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 1.8g of ethane and 4.6g of oxygen gas?

Answers

Answer:

mass of CO₂ produced = 5.06 g of CO₂

Explanation:

Equation of the reaction: 2CH₃CH₃ + 5O₂ ---> 4CO₂ + 6H₂O

From the equation of the reaction, 2 moles of gaseous ethane reacts with 5 moles of oxygen gas to produce 6 moles of water.

molar mass of ethane = 30 g/mol

molar mass of oxygen gas = 32 g/mol

number of moles of ethane present in 1.8 g = 1.8/30 = 0.06 moles

number of moles of oxygen gas present in 4.6 g = 4.6/32 = 0.14375 moles

mole ratio of oxygen gas to ethane  = 2.4 : 1

Therefore, oxygen is the limiting reactant

0.14375 moles of oxygen will react with 0.06 moles of ethane to produce 4/5 * 0.14375 moles of CO₂ = 0.115 moles of CO₂

molar mass of CO₂ = 44 g/mol

mass of CO₂ produced = 0.1725 * 44

mass of CO₂ produced = 5.06 g of CO₂

In an experiment, the theoretical yield of lead sulfate for this reaction was 2.85 g.
In the experiment only 2.53 g of lead sulfate is obtained.
Calculate the percentage yield of lead sulfate in this experiment. * IT​

Answers

Answer:

88%.

Explanation:

The percentage yield of lead sulfate in this experiment is 88% if 2.53 is divided by 2.85 and multiply by 100. The percentage yield can be calculated when the experimental yield is divided by theoretical yield and then multiply by 100. The percentage yield tells us about the actual yield that is gained in the end of experiment which is lower than theoretical yield.

16.1 g of bromine are mixed with 8.42 g of chlorine to give an actual

yield of 21.1 g of bromine monochloride.

Answers

The question is complete, the complete question is;

16.1g of bromine are mixed with 8.42g of chlorite to give an actual yield of 21.1g of bromine monochloride.

Answer:

91 %

Explanation:

Br2 + Cl2 ------>2BrCl

Number of moles of Chlorine = 8.42/71 = 0.119 moles

If 1 mole of Cl2 yields 2 moles of BrCl

0.119 moles of Cl2 will yield 0.119 moles * 2/1 = 0.238 moles of BrCl

Number of moles of Br2 reacted = 16.1/160 = 0.1 moles

If 1 mole of Br2 yielded 2 moles of BrCl

0.1 moles of Br2 yields 0.1 * 2/1 = 0.2 moles of BrCl

Bromine is the limiting reactant.

Mass of BrCl produced = 0.2 moles * 115.357 g/mol = 23.07 g

Theoretical yield = 23.07 g

Actual yield = 21.1 g

Percentage yield = Actual yield/Theoretical yield * 100

= 21.1/23.07 * 100 = 91 %

Stu Dent wants to create a salt water solution. He uses 0.614 moles of salt and 182 milliliters of water. What is the molarity of the solution?

Type your answer...

Answers

Answer: The molarity of solution is 3.37 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

[tex]Molarity=\frac{n\times 1000}{V_s}[/tex]

where,

n = moles of solute = 0.614  

[tex]V_s[/tex] = volume of solution in ml = 182 ml

Now put all the given values in the formula of molarity, we get

[tex]Molarity=\frac{0.614\times 1000}{182}=3.37M[/tex]

Therefore, the molarity of solution is 3.37 M

What is the expected density of the above sample of gas?
A. 1.90 g/L
B. 1.82 g/L
C. 1.56 g/L
D. 1.43 g/L

Answers

Answer:

1.56g/L it will be as per my calculation if I am not wrong so

Answer: D: 1.43

The expected density of the given sample of oxygen gas at STP can be calculated using the ideal gas law equation:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.

At STP, the pressure is 1 atm and the temperature is 273 K. We are given that the mass of the oxygen gas is 4.8 g. To find the number of moles of oxygen gas, we can use its molar mass, which is 32.00 g/mol:

n = mass / molar mass = 4.8 g / 32.00 g/mol = 0.15 mol

Using the molar volume of an ideal gas at STP, which is 22.4 L/mol, we can find the volume of the oxygen gas:

V = n × molar volume = 0.15 mol × 22.4 L/mol = 3.36 L

Therefore, the expected density of the given sample of oxygen gas at STP is:

density = mass / volume = 4.8 g / 3.36 L = 1.43 g/L

Therefore, the expected density of the given sample of oxygen gas at STP is 1.43 g/L.
