What happens to a redox reaction when it is shown as half-reactions answers?

Chemistry

ella [17]3 years ago
8 0
A redox reaction is a combination of an oxidation reaction and a reduction reaction, this reaction involves the transfer of electrons from one species to another. When redox reactions are shown as half reactions you are able to determine what parts of the reaction are being reduced and what is being oxidized. Moreover, you are able to determine if the reaction is spontaneous or not once you see the half reactions. When an element loses an electron in a reaction it is considered to be oxidized however if it gains an electron or multiple electrons then it is reduced. In other words, if the oxidation number increases then it is losing electrons and therefore it is oxidized but if the number is decreasing then it is gaining electrons. Note that electrons have negative charges so this trend only makes sense because of this fact.

The American Heart Association recommends to eat no more than 2,301mg of sodium per day. Convert the mass of
castortr0y [4]

The mass of 2,301 grams of sodium in ounces is 0.0811757609 ounces.

The amount of sodium recommended by American heart association is 2301 mg. This limit should not be crossed in a day.

We have to convert Mass of sodium from mg to ounces.

We know,

1 ounce = 28.3459 grams.

We also know,

1 gram = 1000 milligrams.

So,

28.3459 grams = 28.3459 x 1000 milligrams.

28.3459 grams = 28345.9 milligrams.

1 ounce = 28345.9 mg.

1 mg = 1/28345.9 ounces

Weight of sodium 2301mg in ounces,

2301mg = 2301/28345.9 ounces

Dividing till last significant figure,

2301 mg = 0.0811757609 ounces.

Mass of sodium in ounces is 0.0811757609.
