Please help with question 4 and 5 please!!

ratelena [41]

Question four is : Gaseous state

Question five is : A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. The particles in solids vibrate about fixed positions; even at very low temperatures. Individual particles in liquids and gases have no fixed positions and move chaotically.

Hope this helps!

Have a great day!

Why or how, do electrons receive a positive charge during beta decay?

scZoUnD [109]

Answer: Beta decay occurs when a nucleus is unstable because it has too many or too few neutrons relative to protons. The nucleus emits a beta particle and energy. In beta-minus decay, a neutron breaks down to a proton and an electron, and the electron is emitted from the nucleus.

Draw the structure corresponding to the followingname:_________.

natita [175]

Answer:

See figures 1 and 2

Explanation:

For this question, we can analyze each compound:

a. (4Z,3S)-2,4,7-trimethyl-3-amino-4-octene

In this case, we have to start with a carbon chain of 8 carbons. Then in carbons 2, 4 and, 7, we have to put three methyl groups ( $CH_3$ ). In carbon 4 we have to put an amino group ( $NH_2$ ). When we put the amino group in carbon 4 we will have a chiral carbon. So, we have to indicate the orientation in the bond of the amino group. If we want an "S" configuration the atoms must have a counterclockwise orientation. So, the amino group must have a dashed bond. Finally, in carbon 4 we have to put a double bond, the configuration of this double bond is "Z". So, the most important groups must be on the same side, in this case.

See figure 1 for further explanations

b. (3S,6R)-6-(2,4-dinitrophenyl)-3-amino-1-heptyne

In this case, we have to start with a chain of 7 carbons. In carbon 3 we have to put an amino group ( $NH_2$ ). When we put this group in carbons we will have a chiral carbon is the name we have an "S" configuration for this carbon. So, we have to use the dashed bond in order to have a counterclockwise orientation for all the atoms bonded on carbon 3. In carbon 6 we have to put a big group "2,4-dinitrophenyl". In this group, we have a bond with the main carbon chain in carbon 6 (of benzene), in this same benzene ring we have to put nitro groups ( $NH_2$ ) in carbons 2 and 4. Additionally, carbon 6 is a chiral carbon, and the configuration of this carbon is "R". Therefore we have to use a wedge bond for all the "2,4-dinitrophenyl" in order to have a clockwise orientation for all the atoms bonded on carbon 6. Finally, we have to put a triple bond between carbons 2 and 3.

Help ASAP!!

arlik [135]

Given :

Chlorine's 3p sub level has 5 electrons in it.

To Find :

How many electron(s) more in the 3p sub-level to make it stable.

Solution :

Electronic configuration of Chlorine is :

[Ne] 3s² 3p⁵.

We know, p-orbit is stable with 6 electronic.

Therefore, to stable p-orbit 1 more electron is required in 3p sub-level.

Hence, this is the required solution.
