2O2 IS THE OXIDIZING AGENT BECAUSE IT GIVES ALL OTHER ELEMENT OXYGEN
WARRIOR [948]3 years ago
7 0

Answer:

Oxygen gas (O₂)

Explanation:

Oxidizing agent is one which its self gets reduced and oxidizes the other.

Oxidation is the process where the oxidation number of substance increases while in reduction the oxidation number decreases.

The oxidation number of hydrogen in both methane and water is "+1"

Oxidation number of carbon in methane is "-4"

While its oxidation number in carbondioxide is "+4"

Thus carbon is undergoing oxidation.

While the change in oxidation number of oxygen from O₂ to CO₂ is "0" to -2

Hence it is undergoing reduction and oxidizing carbon.

1. Rank the following compounds in order of decreasing acid strength using periodic trends. Rank the acids from strongest to wea
Softa [21]

Answer:

1. HBr>HCl> H2S >BH3

2.K_a1 very large — H2SO4

K_a1= 1.7 x 10^−2 — H2SO3

K_a1 = 1.7 x 10^−7 — H2S

Explanation:

As one goes down a row in the Periodic Table the properties that determine the acid strength can be observed.

The atoms get larger in radius meaning that in strength, the strength of the bonds get weaker, conversely meaning that the acids get stronger.

For the halogen-containing acids above following the rows and periods, HBr has the strongest bond and is the strongest acid and others follow in this order.

HBr>HCl> H2S >BH3

Acid Dissociation Constant provides us with information known as the ionization constant which comes in handy to measure the acid's strength. The meaning of the proportions are thus, the higher the Ka value, the stronger the acid i.e. it liberates more number of hydrogen ions per mole of acid in solution.

In solution strong acids completely dissociate hence, the value of dissociation constant of strong acids is very high.

Following the cues above on Ka;

K_a1 very large — H2SO4

K_a1= 1.7 x 10^−2 — H2SO3

K_a1 = 1.7 x 10^−7 — H2S

Which factors help you identify the solute and the solvent in a solution? Select all that apply. In a solution, the solvent is p
KatRina [158]

The answers would be:

In a solution, the solvent is present in a greater amount.

In a solutions, the solute dissolves in a solvent.

In general, these are the best answers. The solute is what is being dissolved and the solvent is what dissolves. A solvent comes in greater amounts in a solution and it is the dissolving agent.

For example, sugar and water.

To make a sugar water solution, you will need to dissolve sugar in water. Sugar is the solute in this case because it is what is being dissolved. The water is the solvent, because it dissolves the sugar.

If you had more sugar than water, then you cannot make a solution.
