Answer: According to the Arrhenius concept, an acid is a substance that causes an increase in the concentration of H in aqueous solutions
Explanation:
According to the Arrhenius concept, an acid is a substance that ionizes in the water to give hydronium ion or hydrogen ion and a bases is a substance that ionizes in the water to give hydroxide ion .
According to lewis concept , an acid is a substance that accepts electrons and a base is a substance that can donate electrons.
Answer:
5.59x10^-3 moles
Explanation:
The balanced equation for the reaction is given below:
HCl + KOH —> KCl + H2O
Now we can obtain the number of mole of HCl required to produce 5.59x10^-3 moles of KCl as follow:
From the balanced equation above, 1 mole of HCl produced 1 mole of KCl.
Therefore, 5.59x10^-3 moles of HCl will also produce 5.59x10^-3 moles of KCl.
From the illustration made above, we can see evidently that 5.59x10^-3 moles of HCl is required to produce 5.59x10^-3 moles of KCl
Answer:
The s-block of the periodic table has 1 orbital
we know that each orbital consists of 2 electrons
and since the periodic table arranges the elements on the basis of their atomic number,
the s-block spans 2 groups.
This is also the reason why the p-block spans 6 groups, d-block spans 10 groups and f-block spans 14 groups
The formula mass is 132.14 g/mol
Grams is the units of mass
