How many moles of oxygen gas react to yield 0.200 mole water? . . C5H12(g) + 8 O2(g) = 5 CO2(g) + 6H2O(g)

1 answer:

4 0

C5H12(g) + 8 O2(g) = 5 CO2(g) + 6H2O(g)
molar ratio of H2O to O = 6:8
we have 0.200 moles of H2O so we need 0.200 * 8/6 moles of O2 = 0.267 moles of O2

Therefore, there will be 0.267 moles of O2 gas required to yield 0.2 moles of H20.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

How will four electrons be distributed in three empty 2p atomic orbitals?

VikaD [51]

B
Orbitals fill in a way that all of them first gain one electron, and then they start receiving the second electron if any are left. Thus, the three will fill with one electron each first and then the fourth will go into the first.

Answer:

See below.

Step-by-step explanation:

Ethers react with HI at high temperature to produce an alky halide and an alcohol.

R-OR' + HI ⟶ R-I + H-OR'

Benzylic ethers react by an Sₙ1 mechanism by forming the stable benzyl cation.

PhCH₂-OR + HI ⟶ PhCH₂-O⁺(H)R + I⁻ Protonation of the ether
PhCH₂-O⁺(H)R ⟶ PhCH₂⁺ + HOR Sₙ1 ionization of oxonium ion
PhCH₂⁺ + I⁻ ⟶ PhCH₂-I Nucleophilic attack by I⁻

If there is excess HI, the alcohol formed in Step 2 is also converted to an alkyl iodide:

ROH +HI ⟶ R-I + H-OH

Thus, benzyl ethyl ether reacts to form benzyl iodide (a) and ethanol (b).

The ethanol reacts with excess HI in an Sₙ2 reaction to form ethyl iodide (c).

Write the balanced chemical equation that represents the standard heat of formation of cro3(s) at 298 k.

strojnjashka [21]

The standard heat of formation is the heat released or absorbed when you obtain the CrO₃ compound. So, the reaction basically involves the individual elements of the compound. The complete balanced chemical reaction for the formation of CrO₃ is:

2 Cr + 3 O₂ → 2 CrO₃
