That is the molecular formula of sulfur dioxide
Historically, the first chemical definition of an acid and a base was put forward by Svante Arrhenius, a Swedish chemist, in 1884. An Arrhenius acid is a compound that increases the H+ion concentration in aqueous solution. The H+ ion is just a bare proton, and it is rather clear that bare protons are not floating around in an aqueous solution. Instead, chemistry has defined the hydronium ion(H3O+) as the actual chemical species that represents an H+ion. H+ ions and H3O+ ions are often considered interchangeable when writing chemical equations (although a properly balanced chemical equation should also include the additional H2O). Classic Arrhenius acids can be considered ionic compounds in which H+ is the cation. Table 12.1 "Some Arrhenius Acids"lists some Arrhenius acids and their names.
contains hydrogen atoms. This is answer
Answer:
Explanation:
This experiment demonstrate that a plant don't need only water to grow and increase its mass.
A plant will also need nutrients located in the soil that will help it grow and increase its mass.
Answer:
84%
Explanation:
Fossil Fuels Supply 84 Percent Of Worlds Electricity
The H-atom has fourth energy level with n=4.
This
energy level can have values of orbital angular momentum l = 0, 1, 2, 3
Now each l can also have magnetic momentum ml from – l to l.
Therefore,
l = 0
<span>ml = 0 </span>
l = 1
ml = -1, 0, 1
l = 2
ml = -2, -1, 0, 1, 2
l = 3
ml = -3, -2, -1, 0, 1, 2, 3
Now adding up all the number of ml’s will give us the total
number of orbitals:
orbitals = 1 + 3 + 5 + 7
orbitals = 16
Alternatively, we can simply use the formula:
<span>orbitals = n^2 = 4^2 = 16</span>
