Answer:

They add to its hardness.

Explanation:

Hello,

Water in ecosystems are likely to have dissolved metallic cations such those alkalies and alkaline earth metals form when present in aqueous systems, in this manner, more specifically speaking, calcium ions promote the formation of unsoluble salts such as calcium carbonate, which lead to the increase of the water's hardness that accounts for such cation's content into the water. Therefore, among the following options:

A. They reduce its pH.

B. They decrease its salinity.

C. They add to its hardness.

D. They increase its acidity.

The correct is C. They add to its hardness.

Best regards.

SOMEONE EXPLAIN THIS TO ME?!?!
labwork [276]

Answer:

Determining the pH of substances such as purple grape juice and catsup using test strips can be difficult. Why?

Explanation:

Due to the tartaric acid present in these substances, this is a weak acid and is the predominant type of acid in grapes.

pH meters for these substances, measure the total acidity of the sample and convert it into tartaric acid concentration; The test strips are a qualitative method of measurement and their result can give different opinions.

Arrange the sublevels in ascending order by the number of electrons they can contain. p sublevel s sublevel d sublevel f subleve
inn [45]

Electronic configuration of the atom describes  the arrangemnet of electrons in different shells and subshells ( sublevels).

Now , there are 4 types of sublevels: s, p , d and f . These sublevels have orbital which are spaces with high probability of having an electron and each orbital can have maximum 2 electrons.

Therefore,

s-sublevel has 1 orbital - it can have maximum 2 electrons.

p-sublevel has 3 orbitals - it can have maximum 6 electrons

d-sublevel has 5 orbitals - it can have maximum 10 electrons

f-sublevel has 7 orbitals - it can have maximum 14 electrons.

Hence, the acsending order of sublevels in terms of maximum number of electrons is:

<h2>s < p < d < f</h2>
