If the atoms have 6 protons both are carbon atoms. And the protons are in the nucleus.

If both have the same mass that’s means that both have the same number of protons. With out the value of the mass we can not calculate the number of protons. The neutrons as equal than the protons are in the nucleus.

The one that has a negative charge has 7 electrons. The electron configuration will be 1s2, 2s2, 2p3.

The one that has a positive charge has 5 electrons. The electron configuration will be 1s2, 2s2, 2p1.

Answer from: alleshia2007

Explanation:

Let the two atoms be A and B having same number of protons and same mass number.

Given number of protons is 6

Number of protons in A = 6

Number of protons in B = 6

Mass = number of proton + number of neutron

Since the mass is same therefore we can say that the number of neutrons in both the atoms A and B is also same.

Now for a neutral atom, we know that number of proton = number of electron

Therefore, number of electron on A = 6 electron

number of electron on A = 6 electron

Let, A be negatively charged, so atom A gains one extra electron and therefore the number of electrons on A is 7

and B is positively charged, so atom B looses one electron, so the number of electrons on A is 5.

Electronic configuration for A is 1s2 2s2 2p3

Electronic configuration for B is 1s2 2s2 2p1

So this will be the location of each number of electrons in their respective shells for the two atoms A and B.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = $25^oc$ = 298 k $)0^oc=273kelvins$

$o_3+3no\rightarrow 3no_2,\delta h_{reaction}=? [/)</p><p>[tex]\delta h_{no}=90.4kj/mol$

$\delta h_{no_2}=33.85kj/mol$

$\delta h_{o_3}=142.2kj/mol$

$\delta h_{reaction}=\sum \delta h_{products}-\sum\delta h_{reactants}=3\times\delta h_{no_2}-(3\times \delta h_{no}+\delta h_{o_3})$

$\delta h_{reaction}=33.85-(90.4+142.2)=-311.85kj/mol$

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

$v_{no}=12.00 l,v_{o_3}=8.50 l$

$pv_{no}=n_{no}rt=1atm \times 12.00 l=n_{no}\times 0.0821 atml/k mol \times 298 k$

$n_{no}=0.49 moles$

$pv_{o_3}=n_{o_3}rt=1atm \times 8.50 l=n_{o_3}\times 0.0821 atml/k mol \times 298 k$

$n_{o_3}=0.34 moles$

according to reaction 3 moles no are reacting with 1 mol of $o_3$ ,then 0.49 mol of no will react with $\frac{1}{3}\times 0.49$ moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and $o_3$ is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

$\delta h_{reaction}\times \text{moles of no}=-311.85kj/mol\times 0.49 mol=-152.80kj/mol$

Answer from: Quest

For cyclohexane compounds drawn in a chair conformation: -axial bonds are vertical -equatorial bonds are parallel to two bonds within the ring. thus, as i assume the chair conformation is drawn: -the x group is in an axial position, as are the five other vertical bonds. -three axial bonds are on the top face of the ring -the other three axial bonds are on the bottom face the position of the second substituent on each ring carbon is equatorial. gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other. drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1. click this link and watch some academic videos that may you more understand the topic
