Determine the number of molecules present in 4.56 moles of nitrogen (n2).
Iteru [2.4K]
To calculate the number of molecules, we can simply use this rule:
number of molecules = number of moles x Avogadro's number

In this problem, we have:
number of moles = 4.56 moles
Avogadro's number is a constant = 6.02 x 10^23

Substituting in the above equation, we can calculate the number of molecules as follows:
number of molecules = 4.56 x 6.02 x 10^23
                                  = 2.74512 x 10^24 molecules

The following are in order of increasing boiling temperatures: (A) RbCl
andrew11 [14]

Answer:

Option E

RbCL<CH3OH< CH3Cl< CH4

Explanation:

The boiling temperature of an organic compound increases with the increase in number of carbon atoms and hence as the length of the hydrocarbon chain increases the boiling temperature also increase due to increase in force of attraction between the molecules. Also presence of strong molecules such as OH – COOH also increases the boiling temperature while Cl and other elements with high electronegativity reduces the boiling temperature  

Hence, the correct order of increasing boiling temperature is option E

RbCL<CH3OH< CH3Cl< CH4

A researcher labels C‑6 of glucose 6‑phosphate with C14 and adds it to a solution containing the enzymes and cofactors of the ox
mafiozo [28]

Answer:

D. C14 appears at C‑6 of fructose 6‑phosphate

Explanation:

Conversion of glucose B-phosphate via 6-phospho-

gluconate to pentose phosphate and CO2 followed by conversion

of the pentose phosphate to fructose 6-phosphate and glyceralde-hyde phosphate followed by conversion of the fructose 6-phos-

phate to glucose g-phosphate .

7. Draw the structures for the following hydrocarbons.HydrocarbonCyclohexane(C6H12)Cyclohexene(C6H10)StructureHydrocarbonBenzene
Alborosie

So,

Let's draw the structures for the following hydrocarbons:

Cyclohexane

We can draw it using the fact that it is a cycloalkane with six carbons:

Cyclohexene

It also contains six carbons with a hexagonal form, but the difference is that there's double bond on it:

Benzene

It has six carbons but there's an alternating double bond as follows:

Toluene

It has the same structure as benzene but it is bonded to a methyl group outside the benzene:

A chemist measures the amount of oxygen gas produced during an experiment. She finds that of oxygen gas is produced. Calculate t
baherus [9]

Answer:

This question is incomplete. A fragment of the question is missing. The fragment is:

She finds that 4.87 g of oxygen gas is produced

0.152 moles

Explanation:

Using the formula: mole = mass / molar mass

According to the question, a chemist measures the amount of oxygen gas produced during an experiment. Oxygen gas has the chemical formula: O2. Hence, the molar mass will be:

O2 = 16(2) = 32g/mol

If the mass of the oxygen gas to be 4.87 g of oxygen gas.

Therefore,

moles = 4.87/32

moles = 0.152mol
