This is 2-heptene.

single bonds = ane
double bonds = ene
triple bonds = yne
Travka [436]3 years ago
3 0

Answer: Option (b) is the correct answer.

Explanation:

A hydrocarbon that contains atleast one double bond is known as an alkene. Their general formula is C_{n}H_{2n}.

Since the given hydrocarbon chain has seven carbon atoms so, a prefix "hept" will be added before the name of alkene. Also, a double bond is placed at position 2 on moving from left to right.

Therefore, we can conclude that name of the given compound is 2-heptene.

how many molecule of carbon dioxide are needed to react with excess iron oxide to produce 11.6 g of iron
lesya692 [45]

Answer:

0.16 moles of Carbon

Explanation:

The balanced reaction equation:

2Fe_{2}O_{3} + 3C → 4Fe + 3CO_{2}↑

The mole ratio of Carbon to Iron is 3 : 4 (since Fe2O3 is in excess)

i.e 3 moles of C produces 4 moles of Fe.

If 1 mole of Fe - 55.8g of Fe

? moles - 11.6g of Fe

= \frac{11.6}{55.8} = 0.208 moles

But 3 moles of C - 4 moles of Fe

? moles of C - 0.208 moles of Fe

= \frac{3 *0.208}{4} = 0.16 moles of carbon.

I hope this explanation was clear and useful.

Three students made multiple weighings of a copper cylinder, each using a different balance. Describe the accuracy and precision
Thepotemich [5.8K]
Accuracy is the closeness of a measurement to its true value. Precision is the closeness of more than one measurements to each other. The measurements of Lamant is both accurate and precise while the scale of Colin is the opposite. Kirvin is precise but he is not accurate.

Under equilibrium condition, what is the probability of an electron state being occupied if it is located at the Fermi level
Sav [38]

Answer:

Hi

The Fermi Level is a term used to describe the set of electron energy levels at a temperature of absolute zero. Fermi's energy concept is important for the understanding of the electrical and thermal properties of solids. Both electrical and thermal processes involve energy values of a small fraction of an electron-volt. In thermal equilibrium, the net current of both electrons and holes is zero.
