Answer:
The answer is 414.95 mLExplanation:
To find the volume when the pressure is changed to 546 kPa , we use the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the final volume
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
We have
[tex]V_2 = \frac{384000 \times 590}{546000} = \frac{226560000}{546000} \\ = 414.945054...[/tex]
We have the final answer as
414.95 mLHope this helps you

Carbon-14 is likely to undergo which of the following nuclear decay process, in order to:
a)beta decay; to reduce the number of neutrons
b)alpha decay; to increase the number of protons
c)positron emission; to reduce the number of neutrons
d)electron capture; to increase the number of protons
Answer:
a)beta decay; to reduce the number of neutrons
Explanation:
When an isotope decays by beta decay, a neutron is converted into a proton, an electron and a neutrino (a particle that serves to balance spins). This process reduces the neutron/proton ratio.
During the beta decay of carbon-14, an atom of 14C decays into an atom of 14N. Hence the number of protons in the atom increases by one, creating a nitrogen atom.

1. _____anions are strong nucleophiles that open epoxide rings by an SN2 mechanism.
2. _____tautomers have an O-H group bonded to a C=C.
3. _____are formed from terminal alkynes with the addition of water using BH3 then H2O2.
4. _____are constitutional isomers that differ in the location of a double bond and a hydrogen and exist in an equilibrium with each other.
5. _____are compounds that contain a carbon-carbon triple bond.
6. _____of a terminal alkyne adds BH? to the less substituted, terminal carbon.
7. _____have a C=O and an additional C-H bond.
8. _____are formed from terminal alkynes with the addition of water using H2SO4 and HgSO4.
Answer:
1) acetylide
2) enol
3) aldehydes
4) tautomers
5) alkynes
6) Hydroboration
7) Keto
8) methyl ketones
Explanation:
Acetylide anions (R-C≡C^-) is a strong nucleophile. Being a strong nucleophile, we can use it to open up an epoxide ring by SN2 mechanism. The attack of the acetylide ion occurs from the backside of the epoxide ring. It must attack at the less substituted side of the epoxide.
Oxomercuration of alkynes and hydroboration of alkynes are similar reactions in that they both yield carbonyl compounds that often exhibit keto-enol tautomerism.
The equilibrium position may lie towards the Keto form of the compound. Usually, if terminal alkynes are used, the product of the reaction is a methyl ketone.
