Rows in the periodic table are called periods...on the other hand, columns are called groups.
Answer:
Explanation:
Natural Rain:
"Normal" rainfall is slightly acidic because of the presence of dissolved carbonic acid. ... The gases of sulfur oxides and nitrogen oxides are chemically converted into sulfuric and nitric acids. The non-metal oxide gases react with water to produce acids (ammonia produces a base).Natural Rain:

Answer:
4.504g of acetic acid
Explanation:
The acetic acid in reaction with NaOH produce acetate ion, thus:
CH₃COOH + NaOH → CH₃COO⁻ + H₂O + Na⁺
<em>That means the moles of acetate buffer comes, in the first, from the acetic acid</em>
As you need 500mL (0,500L) of a 0.150M acetate buffer, moles are:
0.500L × (0.150mol / 1L) = <em>0.075 moles of acetate</em>. That is:
0.075mol = [CH₃COO⁻] + [CH₃COOH]
Thus, grams of acetic acid you need to prepare the buffer are:
0.075 moles acetic acid × (60.05g / 1mol) = <em>4.504g of acetic acid</em>
Answer: Option C) The unicellular organism creates a new organism.
Explanation:
Cell division involves the multiplication of cells whereby one cell divides into two daughter cells or offsprings, two divides into four and so on.
In unicellular organisms, cell division could be by the following ways:
- Binary fission in Ameoba
- Budding in Hydra
- fragmentation in Sponges.
Thus, each of these unicellular organisms divides to give rise to new organisms that are similar to their parents
