A triple bond<span> is one </span>sigma<span> and two </span>pi bonds<span>. A </span>sigma bond<span> is your basic head-on covalent </span>bond<span>, with the </span>bond<span> in line with the </span>bonding<span> orbitals. You can only ever have one </span>sigma bond between<span> any two atoms. A </span>pi bond<span> is a covalent </span>bond between<span> orbitals perpendicular to the </span>bond<span> direction, usually p-orbitals (nevers)</span>

Which of the following reactions involves a single compound producing two or more simpler substances?
castortr0y [4]

Answer:

Decomposition or cracking

Explanation:

In a decomposition or cracking reaction, a single compound produces two or more simpler substances.

It involves the formation of two or more products from a single reactant.

  A →  B + C

A is the single reactant

B and C are the products

The driving force for such a reaction is the is high positive heat of formation of the compound that is, extreme instability of the compound.

What are the controlled variables for water of crystallization experiment?
yarga [219]

Given what we know, we can confirm that as with any experiment, the control variable will be the one that through each trial of the experiment, no matter how many times it is performed, stays constant.

<h3>What is a controlled variable?</h3>
  • A variable that remains constant through an experiment.
  • They are used to compare results to the normal condition.
  • They are also used to isolate the changes to one factor at a time and thus know its exact effects on the outcome.
  • This increases the accuracy of the data and the subsequent conclusion.

Therefore, we can confirm that if a variable stays constant through each phase and trial of an experiment, it is considered to be a controlled variable and is useful in order to increase the accuracy of the conclusion.

What would happen to the pressure if the volume were reduced to 0.5 l and the temperature increased to 260 ∘c?
Vsevolod [243]
<span>The ideal gas law. PV=nRT pressure x volume = moles x Faraday's constant x Temp Kelvin (C+273) Original data Pressure 1 atmosphere Volume 1 liter Temp 25C = 298K New data Volume 0.5 liter pressure X Temp 260C = 533K P1v1T1 = P2v2T2 plug and chug. (1)(1)(293) = (x)(0.5)(533) Solve for X, which is the new pressure. </span>

G what is the difference between the sidechains of leucine and isoleucine? select one:
statuscvo [17]

c. Isoleucine has a carbon “branched” closer to the alpha carbon than does leucine.

The structure of leucine is CH3CH(<u>CH3</u>)CH2CH(NH2)COOH.

The structure of isoleucine is CH3CH2CH(<u>CH3</u>)CH(NH2)COOH.

In leucine, the CH3 group is <em>two carbons away</em> <em>from</em> the α carbon; in isoleucine, the CH3 group is on the carbon <em>next to</em> the α carbon.

Thus, <em>isoleucine</em> has the closer branched carbon.

“One is charged, the other is not” is i<em>ncorrect</em>. Both compounds are uncharged.

“One has more H-bond acceptors than the other” is <em>incorrect</em>. Each acid has two H-bond acceptors — the N in the amino and the O in the carbonyl group.

“They have different numbers of carbon atoms” is <em>incorrec</em>t. They each contain six carbon atoms.
