Total pressure of the system = P = 263.0 Torr
At initail
(13.2) Torr (32.8) Torr (13.2) Torr
At equilbriumm
(13.2-x) Torr (32.8-x) Torr (217.0+x) Torr
Solving for x;
x = 6.402 Torr

Answer: The correct answer is Aldose.
-
A disaccharide is produced when two monosaccharides are linked by a glycosidic bond.
- Any carbohydrate which has six carbon atoms is called as hexose. It is a monosaccharide. The functional group in hexose can be aldehyde or ketone.
- Ketose is a carbohydrate which contains ketone as a functional group.
Aldose, as the name suggests, it means having aldehyde group. Thus, it is a carbohydrate which has aldehyde as a functional group.
Example- D- Glyceraldehyde.
Answer:
62.98 % of the sample of hydrate is water
Explanation:
Step 1: Data given
Mass of the sample of a hydrate of sodium carbonate (Na2CO3) = 2.026 grams
After heating, the mass of the sample is 0.750 g
Molar mass H2O = 18.02 g/mol
Step 2: Calculate mass of water
Mass water = mass of hydrate - mass of sample after heating
Mass water = 2.026 grams - 0.750 grams
Mass water = 1.276 grams
Step 3: Calculate mass % percent of water
Mass % of water = (mass of water / total mass hydrate) * 100 %
Mass % of water = (1.276 grams / 2.026 grams) *100 %
Mass % of water = 62.98 %
62.98 % of the sample of hydrate is water
The question is incomplete, here is the complete question:
Carbon tetrachloride reacts at high temperatures with oxygen to produce two toxic gases, phosgene and chlorine.
at 1,000 K
Calculate Kc for the reaction
<u>Answer:</u> The value of for the final reaction is
<u>Explanation:</u>
The given chemical equations follows:
We need to calculate the equilibrium constant for the equation, which is:
As, the final reaction is the twice of the initial equation. So, the equilibrium constant for the final reaction will be the square of the initial equilibrium constant.
The value of equilibrium constant for net reaction is:
We are given:
Putting values in above equation, we get:
Hence, the value of for the final reaction is
