Answer:

Explanation:
Hello,
In this case, since 11 mg per kilogram of body weight has the given lethality, the mg that turn out lethal for a chicken weighting 3 kg is computed by using a rule of three:

Thus, we obtain:

That in grams is:

Only by measuring the separation between the nuclei of two contacting atoms and halving that distance can one determine the radius of an atom. The illustrations show how the environment around an atom can cause it to have a varied radius, even if it is the same atom.
<h3>How can the atomic size of an element be determined?</h3>
By measuring the distance between the two atoms after two are united, we may determine the atomic size of the new molecule. The third technique for determining an element's atomic size is to create a single covalent link between two atoms and measure the space between them.
Atomic radii in the periodic table change from left to right across a row and from top to bottom along a column. Because of these two patterns, the periodic table's bottom left corner contains the biggest atoms, while the upper right corner has the smallest.

Answer:
A.He added bleach to the samples.
Explanation:
Bleach destroys the chemical composition of bacteria. Adding mold spores, freezing samples, and raising the temperature all result in physical changes, but not chemical changes, so specimens remain alive.
