All atoms of the same element have the same
number of protons. Every atom also has a nucleus.
Typical household bleach has a value of pH of 13, so the concentration of H₃O⁺ in household bleach is 1 × 10⁻¹³ M.
<h3>What is pH?</h3>
pH of any solution is defined as the negative logarithm of the concentration of H⁺ ion presnt in the solution.
pH = -log[H⁺]
From this equation we can calculate the concentration of H⁺ ion by removing logarithm as:
[H⁺] = 
Given value of pH = 13
[H⁺] = 10⁻¹³ M
Hence, required concentration is 1 × 10⁻¹³ M.

Answer:
Because when they brought the cows back the Autumn Buttercup began to thrive. They took the cows out of the pasture thinking that the Autumn Buttercup would grow better. They noticed that the Autumn Buttercup was thriving in a field nearby where there were cows grazing.
a.) When the cows ate the grass in the fields, it made the grass shorter that the mice couldn't live there and be safe from their predators.
b.) When the cows walk on the soggy ground it pushes up the soil on the sides of the cow print where the buttercup like to grow and not directly in the soggy soil.
Nature has been developing its habitats for thousands and thousands of years. In time there is a balance where there aren't too many plants and animals, but enough food for each. When there is a change in any habitat and something is taken out or introduces, then it changes the population of different species where it may deplet one type of species and let another type of species overpopulate. It can cause species to extinct. It will take nature hundredsof years to find balance again.
Explanation:
Answer: A = atomic number = 12
Explanation: A (atomic number) defines the chemical element. It is the numbervof protons or electrons. Neutron numbers may vary, produving isotopes of differing atomic mass. This isotope has atomic mass 28. The atomic number 12 = carbon. C28 does not really exist. If it could be produced it would be radioactive with an almost zero halflife.
1 valence electron, are called alkali metals, are metals, react with water
