How to choose the base compound ? And start counting from that ? IS there is a prioty list ?

Derive the midpoint formula for points in the xy-plane.

Derive the distance formula for points in the xy-plane.

I’ve spent the last months building a full mechanical cosmology model from scratch — a “Bubbleverse” simulation framework that evolves from simple single-bubble decay all the way to large-scale cosmic foam. The project now includes: energy-driven universe decay (Mark 1–2) multi-bubble competition and collisions (Mark 3 series) field-driven cosmology with dynamic critical density (Mark 4–6) large-scale foam structures and emergent behavior (Mark 7A–7D) machine-learning analysis of thousands of simulated universes (Mark ML) It’s not standard physics — just a conceptual model — but the full code, figures, phase maps and explanations are available here: Www.bubblever…

In hypergeometric distribution, n= population of n elements, r = sample size, n1 = elements recognized as having some defined criteria, n2 = n - n1 = remaining elements other than n1 . We seek the probability qk such that the sample size r contain exactly k recognized elements provided [math]k \geq 0, k \leq n_1 [/math] if n1 is smaller or [math] k \leq r[/math] if r is smaller. In such a case the probability [math]q_k =\frac{\binom{n_1}{k}\binom{n- n_1}{r - k}}{\binom{n}{r}} \tag {1}[/math] Now, I want to calculate n=8500, n1 =1000, r = 1000, k = 0 to 100. Inserting these values in (1), calculation of summation is very difficult. In such case, how can I use norm…

CnH2n-2d ?

5-isopropyl Iso means 1 branch of methyl on 2nd Propyl is c2h4 not 6 Sec-butyl is c with 2 other c attache and another fcitonal group attached Also iso thing Propy is c3h8 not 6 Here propyl mean C3H5

Also why there is +ve charge on II ?

Is the book self-contradictory or am I tripping. Also what is the order of preference for base substituent ?

'You have already read that the pi (π) bond is a weaker bond due to poor sideways overlapping between the two 2p orbitals." 1 pie bond is actually 2 bonds as it need 2 p orbitals

Title

Chloromethyl ? C3H5 what is that ? 1. Supposed to be CH3Cl which should be Chloromethyl Ethyl Propyl

What is acetate ? not methyl carboxylic acid Why is O negatively charged oxygen has 6 electrons and when bond it's got 7 if it losses 2 what is 5 but the middle part has 7 electrons oxygen has 6 electrons and when bond it's got 7 if it losses 2 what is 5 but the middle part has 7 electrons oxygen has 6 in valence free radicals has single electrons in their orbital in the valence shell, making atom unstable, reactive, shifts electron cloud Reaction is from

Is STP supposed to be 0C 20C or 25C ? I didn't understand anything What is 760 What is 273

5-isopropyl Iso means 1 branch of methyl on 2nd Propyl is c2h4 not 6 Sec-butyl is c with 2 other c attache and another fcitonal group attached Also iso thing Propy is c3h8 not 6 Here propyl mean C3H5 What is tetra What is tert Chloromethyl ? C3H5 what is that ? 1. Supposed to be CH3Cl which should be Chloromethyl Ethyl Propyl What is acetate ? not methyl carboxylic acid Why is O negatively charged oxygen has 6 electrons and when bond it's got 7 if it losses 2 what is 5 but the middle part has 7 electrons oxygen has 6 electrons and when bond it's got 7 if it losses 2 what is 5 but the middle part has 7 electrons oxygen has 6 in valence free radicals has sin…

Problem 7.1 In (i) What takes priority Electron transfer or Electronegative/Positive element ? In (i) Explain addition of Electronegative/Positive element seen as oxidation In (iii) How can Na be oxidized when hydrogen is been added to it ?

Double bond - C2H4 should be longer than C2. And if a more electro negative is added to C2H4 single bond or C2H6 double bond, length should reduce further.

So hi! I can't access my other account since I can't login through facebook at the time so I created this other account. Hi Fellow scientists, I'm a grad student in Wildlife Science and I can't seem to wrap my head in building a phylogenetic tree involving multiple genera. It's not really an assignment but I am kinda falling behind in my class due to this. A help would be greatly appreciated! We had a similar thing in the lab class but this thing is similar to it as we try to list traits and determine their characters states across genera. My conclusion here is that Nyctixalus is the closest to the outgroup; therefore, more basal than the rest. What I start to have tr…

Concept If resonance energy is more that means the means resonance structures have varying energies and it should be less stable aka more energy ? So more resonance energy = More Stability ? Problem 8.16 Does the electron movement be of 1 electron and not a pair. C needs 4 more electrons the 2 hooked arrow shows C is getting 1 extra electron. Problem 8.17 Resonance structure needs to have same no. of unpaired electrons. Why charges develop of II Why is O in III +ve Explain “does not contribute as oxygen has positive charge and carbon has negative charge, hence least stable].” Problem 8.18 In II why would O develop +ve charge Explain the answer Electrometric Effect Book s…

It seems like a miss-print/render H+ is partially positive but still bonded ? Positive charge needs to be on C for it's empty p-orbital to be stabilized by adjacent C-H bon's sigma bond. What is the role of -ve charge on C ?

Ethyl is C2H6. Why why C2H5 is called that here ? Aniline means benzenamine (C₆H₅NH₂) but NH2 is at 1. So it can also be written as 1-amino-4-Ethyl-2-methybenzene ?

Example if carbon is bonds to 3 species we assume it's singly bonded with 2 and doubly bonded with 1 and has hybridization of sp2. Why don't we assume sp3 and there is a negative charge on C ? Is it role of hybridization is to form maximum sigma bonds ? All non-hybridized orbitals form pie bonds ?

In (a) Is the Pie bond of Double and Triple Bond CC different that is why written separately in answer
