How many moles of sodium hydroxide, NaOH, are in a 35.65 g sampleof NaOH? (The molar mass of NaOH is 40.01 g/mol.)

Answers

Answer 1
Answer:

A 35.65 g sample of NaOH contains 0.8910 moles of NaOH.

What is mole?

The mole, denoted by the sign "mol," is the volume of a system that has the same number of atoms in 0.012 kilograms of carbon-12 as there are elementary particles.

The mole, often known as mol, is a SI unit used to measure how many particles are present in a given substance. A mole is made up of 6.02214179 atoms or other fundamental building blocks like molecules.

Mass off NaOH = 39.997

given = 35.65 g of NaOH

No of moles of NaOH =35.65 g of NaOH × 1 mol NaOH /40.01 g

No of moles of NaOH = 0.8910 moles.

Answer 2
Answer:

Answer:

0.8910 mols of NaOH in a 35.65 g sample of NaOH

Explanation:

Mass off NaOH = 39.997

given = 35.65 g of NaOH

35.65 g of NaOH * 1 mol NaOH = 0.8910, since there are 4 sig figs.

Answers

Nitrogen cycle is the series of processess where nitrogen and its compound move through the environment and in living organisms. The processes here include fixation, ammonification, nitrification and denitrification. Majority of Earth's atmosphere is nitrogen.

Predict the organic product formed when phosgene reacts with an excess of methanol.

Answers

When phosgene is reacted with an excess of methanol, this produces dimethyl carbonate. Dimethyl carbonate is used in methylating anilines, phenols, and carboxylic acids, and is also being studied for its use as an alternative additive in fuel.

The industrial production of dimethyl carbonate no longer uses phosgene because of the latter's toxicity. Phosgene widely gained infamy when it was used in chemical warfare during WWI.

What is the average kinetic energy of 1 mole of a gas that is at 100 degrees Celsius?

Answers

To simplify our solutions, we have to assume that the gas we are referring is ideal. The kinetic energy of of ideal gas is a funtion of moles and temperature only. 
KE = (3/2)(nRT)
 = (3/2)(1mol)(8.314J/molK)(100+273.15) = 4204.6J

A rock can be broken down into different kinds of substances by physical processes. No chemical reactions are needed to separate different parts of a rock into pure substances. This is because a rock is a(n) .

Answers

I believe the correct answer is a mixture. Most rocks are just different compounds or elements somewhat fused through heat and pressure. The substances are not chemically bonded together which means that they all retain their chemical identity and therefore can be separated by breaking them up. A good example of this is granite where you can see the different compounds that got fused together and can falls apart when you grind it. I hope this helps. Let me know if anything is unclear.
