Answer:

correct answer is A

Explanation:

Functional group:

The properties of organic compounds are depending on some groups of atom, which is known as functional group. Thus, the compounds, which have same functional group, have similar properties.

For example if the compound contains at least one double bond means it is an example of alkene.

Amines: Amines contain the characteristic –NH2 functional group.

Amine means R-NH2

Methyl amine means CH3NH2

Because meth means one carbon atom only and amine means –NH2 as functional group.

Therefore the correct answer is A

An amine refers to a nitrogen-based compound. Since A is the only option with nitrogen, that would be the answer.

a particular application calls for N2 g with a density of 1.80 g/L at 32 degrees C what must be the pressure of the n2 g in mill

baherus [9]

Answer:

1223.38 mmHg

Explanation:

Using ideal gas equation as:

$PV=nRT$

where,

P is the pressure

V is the volume

n is the number of moles

T is the temperature

R is Gas constant having value = $62.3637\text{ L.mmHg }mol^{-1}K^{-1}$

Also,

Moles = mass (m) / Molar mass (M)

Density (d) = Mass (m) / Volume (V)

So, the ideal gas equation can be written as:

$PM=dRT$

Given that:-

d = 1.80 g/L

Temperature = 32 °C

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15

So,

T = (32 + 273.15) K = 305.15 K

Molar mass of nitrogen gas = 28 g/mol

Applying the equation as:

P × 28 g/mol = 1.80 g/L × 62.3637 L.mmHg/K.mol × 305.15 K

⇒P = 1223.38 mmHg

<u>1223.38 mmHg must be the pressure of the nitrogen gas.</u>

borishaifa [10]

The correct answer is the first choice given. Plants and algaes are producers. They are called as such since they produce their own food by using the energy from the sun, CO2 and water to form glucose as their food.
