Answer:

It must be an alcohol.

Explanation:

For a compound to be amine there must be a nitrogen in it.So the given compound cannot be amine.

For a compound to be carbohydrate it must have a carbonyl group and at least one hydroxyl group. so the compound will have more than one oxygen atoms.

A hydrocarbon cannot have an oxygen in its molecular formula.

Hence the compound must be alcohol.

Also the general molecular formula of monohydric alcohol is CₙH₂ₙO, Which fits the given compound.

Alcohols. C3H7OH is an alcohol named propanol.

Answer:

Nitrogen, $N_2\\$

Explanation:

Hello,

This is a clear example of what the ideal gas equation is used for, thus, from its mathematical definition:

$PV=nRT$

One can spell it out in terms of mass and molar mass:

$PV=\frac{m}{M}RT$

Now, solving for the molecular mass, $M$ :

$M=\frac{mRT}{PV} =\frac{9.5g*0.082\frac{atm*L}{mol*K}*297.15K}{2.00atm*4.1L}\\ M=28.23g/mol$

Now, by taking into account that the gas is diatomic, the matching gas turns out to be nitrogen.

Best regards.

Answer: 27 is A and 28 is C.

Explanation: I’ll explain 28 but not 27 because that’s just definitions.

In CuSO4 there is a Cu, an S, and 4 O molecules. Add them up you get 6.

What part of the atom contains the most space: the nucleus or the energy levels? Why?

Anarel [89]

Answer:

I don't know 100% but im pretty sure its electrons, if im wrong im really sorry let me know in the comments ill change it

explanation

the nucleus has more weight but its more compact but the electrons are spread apart circling the nucleus and therefor take up more space

jonny [76]

Answer:

Conversion factor;

Molar mass;

Avogadro's constant and molar mass

Explanation:

Firstly, an intermediate step is to define the conversion factor that will be then used in a conversion technique called dimensional analysis in order to convert from one unit to another. An example of a conversion factor would be, for example, 1 L = 1000 mL, which can be manipulated as a fraction, either $\frac{1 L}{1000 mL}$ or $\frac{1000 mL}{1 L}$ ;
Secondly, in order to convert mass to moles, we need to know the molar mass of a compound which has a units of g/mol (that is, it shows how many grams we have per 1 mole of substance.
Thirdly, Avogadro's constant, $N_A = 6.022\cdot 10^{23} mol^{-1}$ tells us that there is $N_A$ number of molecules or atoms in 1 mole of substance. We need two conversion factors to convert the number of molecules to a mass: firstly, we need to convert the number of molecules into the number of moles using Avogadro's constant and then we need to use the molar mass to convert the moles obtained into mass.
