<span>After 6 days, only 4 grams of the original amount will remain after 6 days. I have attached an image on how to calculate half-life so you can plug your give value into the formula.

</span><span>
To add, </span>half-life means for<span> a substance decaying exponentially, the amount of time it takes for the amount of the substance to diminish by </span>half.

Which substance loses electrons in a chemical reaction? the one that is oxidized, which is the oxidizing agent the one that is r

victus00 [196]

Answer:

The one that is oxidized or the reducing agent

Explanation:

Oxidation results in loss of electrons or an increase in oxidation state.

Reduction results in gain of electrons or decrease in oxidation state.

The element that undergoes oxidation is said to oxidised, similarly the element that undergoes reduction is said to be reduced.

In a redox reaction, both oxidation and reduction takes place.

If a substrate undergoes oxidation or is oxidised, it is also responsible for reduction of the other species, as the total number of electrons should always be conserved.

The substance that undergoes oxidation, releases some electrons, these electrons are taken by the other substrate and it undergoes reduction.

Hence the substance that undergoes oxidation is called the reducing agent, as it is responsible for reduction of other substrate, when oxidizing itself.

Similar thought works for a substance that undergoes reduction or is reduced, works as an oxidizing agent.

<h3>Answer:</h3>

d) 1 and 4

<h3>Explanation:</h3>

Elements are made up of particles known as atoms.
Atoms of the same element have the same properties as the element.
The atoms of an element may differ in terms of the number of neutrons and have a different mass number, such atoms are known as isotopes.
However, the isotopes have an equal number of protons or atomic number.
In this case, atom 1 has a mass number of 20 and an atomic number of 10 while atom 4 has a mass number of 21 and an atomic number of 21.
Therefore, atom 1 and 4 are isotopes of element E.
