Answer : The correct option is, Octane $C_8H_{18}$

Explanation :

Organic compound : Organic compounds are the chemical compounds in which the one or more atoms of carbon bonded through another elements like hydrogen, oxygen and nitrogen by the covalent bond.

Hydrocarbons are the type of organic compound that contains only hydrogen and the carbon atoms.

Inorganic compound : These are the substance that do not contain carbon bonded to hydrogen.

From the given compounds, we conclude that

The organic compound is : $C_8H_{18}$

The inorganic compounds are : $NH_3,CaS\text{ and }SO_3$

Hence, the correct option is, Octane $C_8H_{18}$

0.052301 km significant figures

lesya [120]

Answer:

Five significant figures.

Explanation:

The given measurement have five significant figures 52301.

All non-zero digits are consider significant figures like 1, 2, 3, 4, 5, 6, 7, 8, 9.

Leading zeros are not consider as a significant figures. e.g. 0.03 in this number only one significant figure present which is 3.

Zero between the non zero digits are consider significant like 104 consist of three significant figures.

The zeros at the right side e.g 2400 are also significant. There are four significant figures are present.

2. The Food and Drug Administration (FDA) mandates that all vinegar sold in the United States must have a minimum concentration

Scilla [17]

Answer:

The minimum molarity of acetic acid in vinegar according to given standards is 0.6660 mol/L.

Explanation:

4% acetic acid by mass means that 4 gram of acetic acid in 100 g solution.

Given that density of the vinegar is same is that of water = 1 g/mL

Mass of the vinegar solution = 100 g

Volume of the vinegar solution = V

$Density=\frac{Mass}{Volume}$

$1 g/mL=\frac{100 g}{V}$

V = 100 mL = 0.1 L

Moles of acetic acid = $\frac{4 g}{60.052 g/mol}=0.0666 mol$

$Molarity=\frac{\text{Moles of solute}}{\text{Volume of solution(L)}}$

$M=\frac{0.0666 mol}{0.1 L}=0.6660 mol/L$

The minimum molarity of acetic acid in vinegar according to given standards is 0.6660 mol/L.

How would one go about solving this?? Thank you.

Marta_Voda [28]

Answer:

5.66g/ml

Explanation:

Mass of Metal Slug, m = 25.17g

Volume of container (flask), v = 59.7ml

Mass of Methanol, M = 43.7g with density, d = 0.791g/ml

Therefore,

Volume of Methanol = M/d = 43.7 / 0.791 = 55.25ml

Volume of Metal slug in the flask = v - V = 59.7 - 55.25 = 4.45ml

Density of Metal slug = mass of metal slug / volume of metal slug

= 25.17 / 4.45 = 5.66g/ml
