Answer:
90% of people marry there 7th grade love. since u have read this, u will be told good news tonight. if u don't pass this on nine comments your worst week starts now this isn't fake. apparently if u copy and paste this on ten comments in the next ten minutes you will have the best day of your life tomorrow. you will either get kissed or asked out in the next 53 minutes someone will say i love you
Explanation:
Answer:
D) will not form any stereoisomers since the product is a saturated hydrocarbon.
Explanation:
Stereoisomerism, or spatial isomerism,refers to a type of isomerism in which two or more molecules have the same molecular formula and atom to atom connectivity but different three-dimensional orientations of those atoms in space.
Stereoisomerism occurs in alkenes because free rotation about the C=C bond is hindered. Thus, the molecule is "locked" in a particular orientation. In a saturated alkane, there is unrestricted free rotation about the C-C bond hence straight chain alkanes do not have steroisomers.
The product formed is 3,4-dimethyl hexane which is a straight chain saturated alkane. This compound does not exhibit stereoisomerism.
Answer:
2.9 is the initial pH of the analyte solution.
Explanation:
The dissociation constant of acetic acid as per theoretical value = 
The initial concentration of acetic acid = c = 0.0900 M
initially
c 0 0
At equilibrium
(c-x) x x
The expression of dissociation constant :
![K_a=\frac{[Ac^-][H^+]}{[HAc]}](https://tex.z-dn.net/?f=K_a%3D%5Cfrac%7B%5BAc%5E-%5D%5BH%5E%2B%5D%7D%7B%5BHAc%5D%7D)
Solving for x:
x = 0.001264 M
![[H^+]=0.001264 M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D0.001264%20M)
The pH of the solution :
![pH=-\log[0.001264]=2.898\approx 2.9](https://tex.z-dn.net/?f=pH%3D-%5Clog%5B0.001264%5D%3D2.898%5Capprox%202.9)
2.9 is the initial pH of the analyte solution.
Answer:
the specimen has 11460 years old
Explanation:
if the live sample has as initial amount of Yo C14, the dead sample will have 0.25Yo of C14.
the rate of decay of radiactive matter over time is
- Y(t) = Yo * e (( - t * Ln2 ) / T)
∴ Y(t) = 0.25Yo; T = 5730
⇒ 0.25Yo = Yo * e (( - t * Ln2 ) / 5730 )
⇒ 0.25 = e (( - t * Ln2 ) / 5730 )
⇒ Ln(0.25) = ( - t * Ln2 ) / 5730
⇒ - 7943.466 = - t * Ln2
⇒ 7943.466 / Ln2 = t
⇒ t = 11460 year
The Enthalpy of Reaction is the adjustment in the enthalpy of a compound response that happens at a consistent weight. It is a thermodynamic unit of estimation helpful for figuring the measure of vitality per mole either discharged or created in a response.
