Heya!!!

Answer to your question:

A catalyst is ______
B. Not used up in a reaction.

Catalyst do not change the amount of reactants or products or itself get used but it just change the rate of reaction.

Hope it helps *_*

Identify the species that is oxidized and the species that is reduced in this reaction. Also, identify the oxidizing agent and t

natulia [17]

Answer:

Given the equation of the reaction below:

3Cl₂(g) + 2Al(s) → 6Cl⁻(aq) + 2Al³⁺(aq)

The oxidized species is aluminum, Al, as its oxidation number increases from zero to +3. Al therefore, acts as the reducing agent.

Also, the reduced species is chlorine gas, Cl₂, as its oxidation number decreases from zero to -1. Therefore, Cl, is the reducing agent.

Note: the question is incomplete. a related question is given as follows; Identify the species oxidized, the species reduced, the oxidizing agent and the reducing agent in the following electron transfer reaction. 3Cl2 + 2Al → 6Cl - + 2Al3+ species oxidized:

Explanation:

An oxidation is a process in which there is a loss of electrons whereas reduction is a process involving the gain of electrons. A redox reaction is a reaction in which oxidation and reduction processes occur concurrently and to the same extent.

In a redox reaction reaction, the substance which is oxidized serves as the reducing agent by donating electrons to the substance which is reduced. On the other hand, the substance which is reduced serves as the oxidizing agent by accepting the electrons donated by the substance which is oxidized. In oxidation, the oxidation number of the substance oxidized increases, whereas in reduction, the oxidation number of the substance decreases.

For example, given the equation of the reaction below:

3Cl₂(g) + 2Al(s) → 6Cl⁻(aq) + 2Al³⁺(aq)

The oxidized species is aluminum, Al, as its oxidation number increases from zero to +3. Al therefore, acts as the reducing agent.

Also, the reduced species is chlorine gas, Cl₂, as its oxidation number decreases from zero to -1. Therefore, Cl, is the reducing agent.

In a synthesis reaction you start with 1.7L of Hydrogen how many liters of water will be produced?

vodomira [7]

Answer:

1.7L

Explanation:

Given parameters:

Volume of hydrogen gas = 1.7L

Unknown:

Volume of water produced = ?

Solution:

A synthesis reaction is a combination reaction that involves two or more substances combining together to give a product.

In the synthesis of water, hydrogen gas and oxygen gas are reacted to give water as a product according to the expression below;

2H₂ + O₂ → 2H₂O

Assuming that the reaction takes place at STP, it is easier to solve this problem.

Now, oxygen gas must be the excess reactant because it is freely available.

Find the number of moles of the known specie first,

Number of moles = $\frac{volume of gas }{22.4}$

Number of moles of H₂ = $\frac{1.7}{22.4}$ = 0.076moles

From the balanced reaction equation;

2 moles of H₂ produced 2 moles of H₂O

0.076 moles of H₂ will produce 0.076 moles of H₂O;

Volume of water produced = number of moles x 22.4

= 0.076 x 22.4

= 1.7L
