Answer:

Organic Chemistry is the study of the structure, properties, composition, reactions, and preparation of carbon-containing compounds, which include not only hydrocarbons but also compounds with any number of other elements, including hydrogen (most compounds contain at least one carbon–hydrogen bond), nitrogen, oxygen,etc

. Study of structure determines their chemical composition and formula.

In a compound the elements are _____ together, whereas in a mixture the substances are blended together.

Salsk061 [2.6K]

Answer:

bonded

Explanation:

Compounds are two elements bonded together.

A mixture is multiple substances blended together. The substances aren't bonded together and can easily be extracted from each other.

In a 5.609g of H20, how many molecules H20<br> arc<br> present?

nignag [31]

Answer:

1.88 x 10²³molecules of H₂O

Explanation:

Given parameters:

Mass of H₂O = 5.609g

Unknown:

Number of molecules of H₂O = ?

Solution:

To solve this problem, we need to find the number of moles of given compound first.

Number of moles = $\frac{mass}{molar mass}$

Molar mass of H₂O = 2(1) + 16 = 18g/mol

Number of moles = $\frac{5.609}{18}$ = 0.31mole

From mole concept;

1 mole of a substance contains 6.02 x 10²³molecules

0.31 mole of H₂O will therefore contain 0.31 x 6.02 x 10²³molecules

= 1.88 x 10²³molecules of H₂O

A 3.31-g sample of lead nitrate, pb(no3)2, molar mass = 331 g/mol, is heated in an evacuated cylinder with a volume of 2.11 l. t

bearhunter [10]

The equation in this problem is: 2Pb(NO3)2(s) --> 2PbO(s) + 4NO2(g) + O2(g)

And the question is what the pressure in the cylinder is after decomposition and cooling to a temperature of 300 K.

Solution:

Moles of Pb (NO3)2 = 3.31/331 = 0.0100

2 moles of Pb (NO3)2 will decay to mold 4 moles of NO2 and 1 mole of O2. So 0.0100 moles of Pb (NO3)2 will form 0.02 moles of NO2 and 0.00500 moles of O2

Then use the formula: PV = nRT.

P = (0.02 + 0.005) * 0.082 * 300 / 1.62

= 0.380 atm
