PLEASE HELP :"( DUE NOW!!

Chemistry
1 answer:
Citrus2011 [14]4 years ago
5 0

Answer:

The correct answer is  

[CH4][H2O]/[CO][H2]3

Option 3 is correct

Explanation:

Step 1: Data given

For the equation aA + bB ⇆ cC + dD

The equilibrium constant is [C]^c * [D]^d / [A]^a*[B]^b

Step 2: Calculate the equilibrium constant Kc

CO+3H2⇌CH4+H2O

Kc = [H2O][CH4] / [CO][H2]³

The correct answer is  

[CH4][H2O]/[CO][H2]3

Option 3 is correct

which term is used when sugar is completely dissolved in water                                                                 
GaryK [48]
The term which is used is homogeneous.
when sugar is completely dissolved in the water, the mixture or solution homogeneous, both in same phase and same uniform texture that is liquid.
There two types of mixtures are heterogeneous and homogeneous in different phases.
If sugar is not completely dissolved in water and you see the crystals of sugar in water, then the solution will be heterogeneous.

Calculate the mass of gold (0.130 J/g°C) that requires 468 J to heat the metal from 21.6 °C to 33.2 °C?
Lemur [1.5K]

Answer:

The mass of gold is found to be 310.34 g.

Explanation:

We have:

Specific heat of gold = C = 0.130 J/g.°C

Heat = H = 468 J

Change in Temperature = ΔT = 33.2 °C - 21.6 °C = 11.6 °C

Now, to find mass of gold we first calculate the amount of heat required to heat the unit mass of gold to specified temperature:

Mass Specific Heat = C * ΔT

Mass Specific Heat = (0.130 J/g.°C)(11.6 °C)

Mass Specific Heat = 1.508 J/g

Now, for the mass of gold (m):

mass of gold = Heat/Mass Specific Heat

mass of gold = 468 J/1.508 J/g

<u>mass of gold = 310.34 g</u>

identify the reagents necessary to achieve each of the following transformations o3 dms, pcc, ch2cl, h2so4,h2o,hgso4
hoa [83]

the reagents necessary to convert alcohol to ketoneNa_2Cr_2O_7 , H_2O which involves oxidation of alcohols.

<h3>What is oxidation of alcohols?</h3>
  • Alcohol oxidation is a significant organic chemistry process. Secondary alcohols can be oxidized to produce ketones, while primary alcohols can be oxidized to produce aldehydes and carboxylic acids.
  • In contrast, tertiary alcohols cannot be oxidized without the C-C bonds in the molecule being broken.
  • In order to cause primary alcohols to oxidize into aldehydes
  1. Cr_2O_7 ^-^2 (dichromate)
  2. CrO_3/pyridine (Collins reagent)
  3. Chromium pyridinium compound (PCC)
  4. Dichromate of pyridinium (PDC, Cornforth reagent)
  5. Periodinane by Dess-Martin
  6. Oxalyl chloride with dimethylsulfoxide (DMSO) for Swern
  • oxidation of secondary alcohols to ketones
  1. Cr_2O_7 ^-^2 (dichromate)
  2. CrO_3/pyridine (Collins reagent)
  3. Chromium pyridinium compound (PCC)
  4. Dichromate of pyridinium (PDC, Cornforth reagent)
  5. Periodinane by Dess-Martin
  6. Oxalyl chloride and dimethyl sulfoxide (DMSO) (Swern oxidation)
  7. CrO_3, H_2SO_4/acetone (Jones oxidation)
  8. Acetone with aluminum isopropoxide (Oppenauer oxidation)
