The question is incomplete. The complete question is :

Hydrogen (H_2) gas and oxygen (O_2) gas react to form water vapor (H_2O). Suppose you have 11.0 mol of H_2 and 13.0 mol of O_2 in a reactor. Calculate the largest amount of H_2O that could be produced. Round your answer to the nearest 0.1 mol .

Solution :

The balanced reaction for reaction is :

$2H_2(g) \ \ \ \ + \ \ \ \  \ O_2(g)\ \ \  \rightarrow \ \ \ \ 2H_2O(g)$

11.0                      13.0

11/2                       13/1     (dividing by the co-efficient)

6.5 mol               13 mol    (minimum is limiting reagent as it is completely consumed during the reaction)

Therefore, H_2 is limiting reagent. It's stoichiometry decides the product formation amount from equation above it is clear that number of moles for H_2O will be produced = number of moles of H_2

                                     = 11.0 mol

Consider the following data for five hypothetical elements: Q, W, X, Y, and Z. Rank the elements from most reactive to least rea
Natalka [10]

Answer:

Y, Q, W, Z and X

Y > Q > W > Z > X

Explanation:

To know the most reactive element, the element will be able to displace other metal in it compound. We also have to observe if the reaction occur. If the reaction didn't occur, that means the element is not reactive than the metal found in the other reactant. Invariably their will be no displacement.

Q + w+ Reaction occurs

Q element displace the metal w in it compound . This means Q is more reactive.

x +z+ No reaction

No reaction here. This means x is less reactive than z as it couldn't displace z in it compound.

w + z+ Reaction occurs

w is more reactive than z as it displaces z in it compound.

Q+ + Y Reaction occurs

Y is more reactive than Q as it displaces Q in it compounds.

Therefore, the most reactive to the least reactive is arrange as follows.

Y, Q, W, Z and X

Solid Magnesium reacts with a Iron (II) Chloride solution ->
photoshop1234 [79]

Answer:

Magnesium + iron chloride   →    iron + magnesium chloride

Explanation:

It is the single replacement reaction.

Single replacement:

It is the reaction in which one elements replace the other element in compound.

AB + C → AC + B

Molecular equation:

Magnesium + iron chloride   →    iron + magnesium chloride

Chemical equation:

Mg(s)  + FeCl₂(aq)       →     MgCl₂(aq) + Fe(s)

Ionic equation:

Mg(s)  + Fe²⁺(aq) + 2Cl⁻(aq)       →     Mg²⁺(aq) + 2Cl⁻(aq) + Fe(s)

Net ionic equation:

Mg(s) + Fe²⁺(aq)      →   Fe(s) + Mg²⁺(aq)

Name the following ester molecule:OA. ethyl butanoateB. propyl pentanoateC. methyl heptanoateD. methylpropanoate
disa [49]

Answer

A. ethyl butanoate

Explanation:

Esters are known for their distinctive odors and are commonly used for food aroma and fragrances. The general formula of an ester is RCOOR'.

Esters are formed through reactions between an acid and an alcohol with the elimination of water.

Esters are named as if the alkyl chain from the alcohol is a substituent. No number is assigned to this alkyl chain. This is followed by the name of the parent chain from the carboxylic acid part of the ester with an –e remove and replaced with the ending –oate.

Hence, the name of the given ester is:

A. ethyl butanoate
