Answer:

4-Methyl-1-pentene

Explanation:

According to the International Union of Pure and Applied Chemistry (IUPAC), IUPAC nomenclature of organic chemistry is defined as the system of naming organic chemical compounds.

There are certain rules for naming organic chemical compounds as per IUPAC. The name of given (CH3)2CHCH2CH=CH2 will be based on the same rules.

At first find out the longest continuous chain and number the chain consecutively (preference given to double and single bonds), so numbering will start from right to left. the given chemical is 5 Carbon chain long.
Then, identify the groups attached to this chain. Methyl is the only group attached to this chain at 4 Carbon.
Assemble the name in alphabetical order using the full name using correct prefix and suffix.

4-Methyl-1-pentene is the name of this chemical, as methyl is in 4th carbon position, Pent for 5 carbon chain and -ene (suffix) for one double bond).

Hence, the correct answer is "4-Methyl-1-pentene".

For the following reaction, calculate how many moles of NO2 forms when 0.356 moles of the reactant completely reacts.

Nesterboy [21]

Answer:

0.712 mol of NO₂ are formed .

Explanation:

For the reaction , given in the question ,

2 N₂O₅ ( g ) → 4 NO₂ ( g ) + O₂ ( g )

From the above balanced reaction ,

2 mol of N₂O₅ reacts to give 4 mol of NO₂

Applying unitary method ,

1 mol of N₂O₅ reacts to give 4 / 2 mol of NO₂

From the question , 0.356 mol of N₂O₅ are reacted ,

now, using the above equation , to calculate the moles of the NO₂ , as follow -

Since ,

1 mol of N₂O₅ reacts to give 4 / 2 mol of NO₂

0.356 mol of N₂O₅ reacts to give 4 / 2 * 0.356 mol of NO₂

Calculating ,

0.712 mol of NO₂ are formed .

In an electrolytic cell, the magnitude of the standard cell potential is the:______

melamori03 [73]

Answer:

a. minimum voltage that must be supplied for a redox reaction to occur

c. always equal to Eanode - Ecathode

Explanation:

In an electrolytic cell; The electromotive force(the maximum standard potential difference) of the cell formed by the system is defined as the standard electrode potential of the right handed electrode minus the standard electrode potential of the left hand electrode. (i.e $\mathbf{E^{\theta}_{cell}=E_{anode} - E_{cathode}}$ )

As we all known that the process by which chemical energy is being converted to electrical energy is called the Electrochemical cell. It consists of two half cells , an oxidation half cell reaction and a reduction half-cell reaction.The overall redox reaction results in a flow of electrons in an electric current which is produced by a minimum voltage.

Therefore, option a and c are both correct.

If Jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, _____... is being

Pachacha [2.7K]

Answer;

-Work

If Jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, work is being done.

Explanation;

Work refers to the application of a given force over a distance. Thus, we can say work is the product of force and distance.
Energy on the other hand is the ability of a body to change, its location, shape, or state of another body.
According to the work-Energy principle, a change in the kinetic energy, which is the energy possessed by a body in motion, is equivalent to the net work done on the body.
