Answer:

3.193 mol

Explanation:

The reaction is

$N_2+3H_2\rightarrow 2NH_3$

We use the stoichiometry in order to find the moles of nitrogen required.

$9.58\ \text{mol of }NH_3\times \dfrac{1\ \text{mol of }N_2}{2\ \text{mol of }NH_3}$

$=3.193\ \text{mol of }N_1$

The amount of nitrogen required is 3.193 mol to produce 9.58 mol of ammonia.

If you dilute 40.0 mL of a 7.0 M solution to make 100.0 mL of solution, what is the molarity of the dilute solution?

Burka [1]

Answer:

2.8M

Explanation:

The following data were obtained from the question:

Volume of stock solution (V1) = 40mL

Molarity of the stock solution (M1) = 7M

Volume of diluted solution (V2) = 100mL

Molarity of diluted solution (M2) =?

Using the dilution formula, we can easily find the molarity of the diluted solution as follow:

M1V1 = M2V2

7 x 40 = M2 x 100

Divide both side by 100

M2 = (7 x 40)/100

M2 = 2.8M

Therefore, the molarity of the diluted solution is 2.8M

Read the descriptions below of two substances and an experiment on each. Decide whether the result of the experiment tells you t

d1i1m1o1n [39]

Answer:

Both sample A and B are mixtures .

Explanation:

Sample A

The given sample has density of .77 g / ml and a component of sample that is separated from vaporization has different density of 1.04 g / mL . From this density it appears that it is water . So sample a appears to be a mixture of water and another matter having lesser density and it is water soluble .

Sample B

It is also a mixture . One component is soluble in water and the other black component is not soluble in water . The soluble component gets dissolved in water and get separated and filtered out . The insoluble part remains stuck to filter paper .

Stearic acid, fatty acid commonly found in animal fat has a condensed Chemical formula CH3(CH2)16COOH. It is a common component

timofeeve [1]

Answer:

The correct answer is option C.

Explanation:

A. The -COOH group would experience hydrogen bonding with water.

The statement is true because , double bonded oxygen atom of carboxylic group interacts with hydrogen atom of water molecule and oxygen atom of water molecule is in same interaction with hydrogen atom of carboxylic acid.

B. The long alkane ''tail" $CH_3(CH_2)_{16} -$ , is hydrophobic.

The statement is true because , region which do not interacts with water molecule is termed as hydrophobic region and region which do interacts with water molecule is termed as hydrophilic region. Generally ,alkanes are are hydrophobic in nature so is the alkane chain in stearic acid.

C. Stearic acid and water are probably miscible.

The statement is false because of higher hydrophobic region the interaction between the acid molecules and water molecules results in immiscibility.

D. Stearic acid would probably dissolve in non polar solvents such as hexane $C_6H_{14}$ .

The statement is true because of hydrophobic part in stearic acid is larger so that is why it get easily dissolve in non polar solvents.

E. Stearic acid contains hydrophobic regions

The statement is true because of higher hydrophobic region due to which they easily get dissolved in organic and non polar solvents.
