In the decomposition of water, how many grams of hydrogen gas and oxygen gas are produced from 23.44 g of water?
djyliett [7]

Answer:

2.60 g of H₂ and 20.8 g of O₂ are produced in the decomposition of 23.44 g of water

Explanation:

Water decomposition is:

2H₂O → 2H₂ + O₂

We convert the mass of water, to moles:

23.44 g . 1 mol/18 g = 1.30 moles

Ratio is 2:2 with hydrogen and 2:1 with oxygen. Let's make rules of three:

2 moles of water can produce 2 moles of hydrogen gas and oxygen gas

Then, 1.30 moles will produce:

(1.30 . 2) /2 = 1.30 moles of H₂

(1.30 . 1) /2 = 0.65 moles of O₂

We convert the moles to mass

1.30 moles of H₂ . 2g / 1mol = 2.60 g of H₂

0.65 moles of O₂ . 32 g / 1 mol = 20.8 g of O₂

For the following reaction conditions select the correct statement regarding the reaction below.
larisa [96]

Answer:

B

Explanation:

The appropriate diagram of the question is shown in the first image attached below.

From the diagram, we see the reaction of Cyclopentanol taking place under Tscl pyridine. We are to show the reaction mechanism and determine from the options, which appropriate product fits in.

So, from the reaction, the hydroxyl substituent reacts with Tscl where cl is being lost. This process is followed by an attack of N substituent on the pyridine with the Hydrogen atom and cleaves off for the structure to form a stable structure. The stereochemistry of the compound remains unchanged and it maintains its stick formula.

Thus, X is the appropriate and the correct product.
