Answer:

16.8dm3

Explanation:

2 moles of CO gives 1 mole of N2

2 moles of CO= 2* 28= 56g

1 mole of N2 = 1* 22.4dm

56g of CO gives 22.4dm3 of N2

42.7 of CO will give> (42.7*22.4)/56

=16.8dm3

There is a type of algae that lives in the cells of corals. These algae process carbon through photosynthesis and pass it on to
Blizzard [7]

Corals will continue to expel algae from their cells if global warming continues, in order to avoid poisonous buildup. Corals will perish as a result of this. The algae are not protected and cannot perform photosynthesis without the presence of corals. The algae will also perish as a result of this.

I know the correct answer is either a or d. Can anyone explain which one it is and why? CH3C ≡ CCH2CH2Cl is named: a. 1-chloro-3
lara31 [8.8K]

Answer:

D.

Explanation:

CH₃C≡ CCH₂CH₂Cl

Since there are 5 carbons so the suffix used is "pent"

There is a triple bond so its alkyne

So the compound becomes 2-pentyne (2 because the triple bond is with the 2nd carbon)

Then,

The functional group of chlorine is attached with 5th carbon So the compound becomes

5-chloro,2-pentyne

The chemist discovers a more efficient catalyst that can produce ethyl butyrate with a 78.0 % yield. How many grams would be pro
zepelin [54]

7.66g of ethyl butyrate is produced.

The reaction is

CH₃CH₂CH₂COOH + CH₃CH₂OH ----> CH₃CH₂CH₂COOCH₂CH₃

  • The molar mass of butanoic acid is 88.11g/mol
  • We have 7.45g of butanoic acid
  • The moles of butanoic acid we have is 7.45/88.11 = 0.0845 mol
  • If the yield is 100%,  1 mole of butanoic acid gives 1 mole of ethyl butyrate
  • But the reaction yield is 78%
  • 1 mole of butanoic acid gives 0.78 mole of ethyl butyrate

From 0.0845 mol of butanoic acid we get 0.78 x 0.0845 = 0.66 mol of ethyl butyrate.

The molar mass of ethyl butyrate is 116.16g/mol

So 0.66 x 116.16 = 7.66g

7.66g of ethyl butyrate is produced.

harina [27]
  Then  product  forms   at  the  cathode is  Fe  metal

Fei3   
undergo   dissociate  to  form  fe^  3+    +   3I^-

Fe^3+  move  to  the  negative   electrode(cathode)  where   they  are   reduced   to  metallic  iron  by  gaining 3e-

that  is  Fe^3+(aq)   +  3e-  = Fe(s)
