Answer:

Cl is not a compound because compounds are made up of atoms from MORE than one element. Since Cl is a singular element is cannot be a compound

Explanation:

Just think of it as Compounds are always more than one elements are always Single

In a redox reaction, electrons are transferred from the substance being reduced to the oxidizing agent.

babymother [125]

<u>Answer:</u> The correct answer is from the substance being oxidized to the substance being reduced.

<u>Explanation:</u>

Redox reaction is defined as the reaction in which oxidation and reduction reaction occur simultaneously.

Oxidation reaction is defined as the reaction where an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.

$X\rightarrow X^{n+}+ne^-$

Reducing agents are defined as the agents which reduces the other substance and itself gets oxidized. These agents undergoes reduction reactions.

Reduction reaction is defined as the chemical reaction where an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

$X^{n+}+ne^-\rightarrow X$

Oxidizing agents are defined as the agents which oxidize other substance and itself gets reduced. These agents undergoes reduction reactions.

Electrons are transferred from one atom to another in this type of reaction from the substance which is getting oxidized to the substance which is getting reduced.

It can also be said that, electrons are transferred from reducing agent to the oxidizing agent.

Hence, the correct answer is from the substance being oxidized to the substance being reduced.

Which statement is true about a base when it reacts with another substance?

Nostrana [21]

Answer: a. It receives a hydrogen ion.

Explanation: Base is a species which is capable of donating its negative quantity and accepting the positive one.

For example, ammonia is considered as a base because it is capable of donating its lone pairs of electrons and can accept an proton as well.

Here, out of the given options, Hydrogen $H^{+}$ is a proton which is acting as a positive species and hydroxide ion $OH^{-}$ is a negative species.

Thus, option (A) is the correct answer as it will receive a hydrogen ion from another base making itself a conjugate acid.

Gaseous methane reacts with gaseous oxygen gas to produce gaseous carbon dioxide and gaseous water . If of carbon dioxide is pro

yaroslaw [1]

The question is incomplete, the complete question is;

Gaseous methane (CH4) reacts with gaseous oxygen gas (O2) to produce gaseous carbon dioxide (CO2) and gaseous water (H2O). If 28.2 g of carbon dioxide is produced from the reaction of 15.1 g of methane and 81.2 g of oxygen gas, Calculate the percent yield of carbon dioxide. Be sure your answer has the correct number of significant digits in it.

Answer:

71.1%

Explanation:

The balanced reaction equation must first be written;

CH4 (g) + 2O2 (g) → CO2 (g) + 2H2O (g)

Let us obtain the number of moles of carbon dioxide corresponding to 28.2 g

Number of moles = mass/ molar mass= 28.2/44.01 g/mol = 0.64 moles of CO2

Next, we obtain the limiting reactant. This is the reactant that yields the least amount of product.

For methane;

Number of moles in 15.1 g= mass/molar mass= 15.1/16gmol-1 = 0.9 moles

From the reaction equation;

1 mole of methane yields 1 mole of carbon dioxide

Hence 0.9 moles of methane yields 0.9 moles of carbon dioxide.

For oxygen

Number of moles of oxygen corresponding to 81.2 g of oxygen= mass/ molar mass= 81.2g/32gmol-1 = 2.5 moles of oxygen

From the reaction equation;

2 moles of oxygen gas yields 1 mole of carbon dioxide

2.5 moles of oxygen gas yields 2.5 × 1 /2 = 1.25 moles of carbon dioxide.

Methane is the limiting reactant.

Theoretical yield of carbon dioxide= 0.9 moles

Actual yield of carbon dioxide= 0.64 moles

% yield = actual yield/ theoretical yield × 100

% yield= 0.64/0.9 ×100

% yield = 71.1%

I NEED HELP PLEASE, THANKS! :)

Answer:

See explanation

Explanation:

A double replacement reaction is a reaction where the atoms in the molecules replace each other to form two new molecules. However, if the products of the solution are soluble, then they could combine with the solution, and form a different set of products than expected.

Hope this helps!
