Alkanes do not have a double bond, thus they are saturated. This makes them the simplest form of hydrocarbon, containing only hydrogen and carbon atoms. They are not very reactive as they don't have a double bond which can open up and join on to other molecules.

Answer:

A related group of hydrocarbons is called the alkynes. These are unsaturated hydrocarbons that possess one or more triple-carbon bonds. They follow the same naming rule as the alkanes.

Consider two bonds, A and B. Both bonds presently are selling at their par value of $1,000. Each pays interest of $120 annually.
Dima020 [189]

Answer:

The answer is "Option b"

Explanation:

The longer its maturity, therefore higher the rise in prices as the interest rate changes, therefore higher the value from both bonds, but bond B is greater than bond A.

Dimethyl sulfoxide [(ch3)2so], also called dmso, is an important solvent that penetrates the skin, enabling it to be used as a t
Bas_tet [7]

The molecular formula of dimethyl sulfoxide is (CH_{3})_{2}SO. Molar mass of dimethyl sulfoxide is 78.13 g/mol. Calculate number of moles as follows:

n=\frac{m}{M}=\frac{7.14\times 10^{3} g}{78.13 g/mol}=91.38 mol

From the molecular formula, 1 mole of dimethyl sulfoxide contains 2 moles of Carbon, 6 moles of Hydrogen, 1 mole of Sulfur and 1 mole of oxygen.

Thus, 91.38 moles of dimethyl sulfoxide will have:

Carbon :

n_{C}=2\times 91.38 moles=182.77 moles

Hydrogen:

n_{H}=6\times 91.38 moles=548.28 moles

Sulfur:

n_{S}=1\times 91.38 moles=91.38 moles

Oxygen:

n_{O}=1\times 91.38 moles=91.38 moles

Since, 1 mole of an element equals to 6.023\times 10^{23} atoms thus, number of atoms can be calculated as:

Carbon:

1 mole\rightarrow 6.023\times 10^{23} atoms

Thus,

182.77 moles\rightarrow 182.77\times 6.023\times 10^{23} atoms=1.10\times 10^{26} atoms

Hydrogen:

1 mole\rightarrow 6.023\times 10^{23} atoms

Thus,

548.28 moles\rightarrow 548.28\times 6.023\times 10^{23} atoms=3.30\times 10^{26} atoms

Sulfur:

1 mole\rightarrow 6.023\times 10^{23} atoms

Thus,

91.38 moles\rightarrow 91.38\times 6.023\times 10^{23} atoms=5.50\times 10^{25} atoms

Oxygen:

1 mole\rightarrow 6.023\times 10^{23} atoms

Thus,

91.38 moles\rightarrow 91.38\times 6.023\times 10^{23} atoms=5.50\times 10^{25} atoms

Therefore, number of C, S, H and O atoms are 1.10\times 10^{26}, 5.50\times 10^{25}, 3.30\times 10^{26} and 5.50\times 10^{25} atoms respectively.
