Answer:
X₂Y₃
Explanation:
X⇒X³⁺ + 3e⁻ /×2
Y + 2e⁻ ⇒ Y²⁻ /×3
2X⇒2X³⁺ 6e⁻
3Y + 6e⁻⇒ 3Y²⁻
2X + 3Y ⇒2X³⁺ + 3Y²⁻ ⇒ X₂Y₃
Electron from one side and from other side can be shortened so we multiply half equations to get equivalent number of electrons on both side. Next step is summing these two half equations. Element Y takes two electrons from element X, so X become positive charged, and Y become negatively charged. It is very likely that element Y have greater electronegativity.
Answer:
1)The proximity of the positively charged phosphorous and negatively charged carbon stabilizes the charges.
2) Inductive effects and resonance stabilize the negative charge
Explanation:
both atoms have full octets of electrons( I.e Carbon and say phosphorus). The result can be viewed as a structure in which two adjacent atoms are connected by both a covalent and an ionic bond; normally written X+–Y−. Ylides are thus 1,2-dipolar compounds, and a subclass of zwitterions
Answer:
B represents gas at room temperature and C represents hot gas.
Explanation:
- <em>As the temperature increases, the no. of particles that has higher energy increases.</em>
So, A represents the cold gas, because it has the lowest no. of particles that has high energy.
B represents the gas at room T because it has more no. of particles with higher energy.
C represents the hot gas, because it is the curve that has the highest no. of particles with high energy.
<em>B represents gas at room temperature and C represents hot gas.</em>
Answer: the answer is option (D). k[P]²[Q]
Explanation:
first of all, let us consider the reaction from the question;
2P + Q → 2R + S
and the reaction mechanism for the above reaction given thus,
P + P ⇄ T (fast)
Q + T → R + U (slow)
U → R + S (fast)
we would be applying the Rate law to determine the mechanism.
The mechanism above is a three step process where the slowest step seen is the rate determining step. From this, we can see that this slow step involves an intermediate T as reactant and is expressed in terms of a starting substance P.
It is important to understand that laws based on experiment do not allow for intermediate concentration.
The mechanism steps for the reactions in the question are given below when we add them by cancelling the intermediates on the opposite side of the equations then we get the overall reaction equation.
adding this steps gives a final overall reaction reaction.
2P + Q ------------˃ 2R + S
Thus the rate equation is given as
Rate (R) = K[P]²[Q]
cheers, i hope this helps
<span>Electrons in a nitrogen-phosphorus covalent bond are not shared equally because nitrogen and phosphorus do not have the same electronegativity. The atoms spend more time around the most electronegative atom nitrogen.</span>
