Answer:
The strong acids are fully ionized in aqueous solution, and they contains higher concentration of hydrogen ions. Strong acids are lower pH in nature. Some examples of strong acids are:
1) Hydrochloric acid.
2) Nitric acid.
3) Sulfuric acid.
The weak acids are not fully ionized, means they are partially ionized in aqueous solution, and they contains lower concentration of hydrogen ions. Weak acids are higher pH in nature than strong acid. Some examples of weak acids are:
1) Ethanoic acid.
2) Acetic acid.
3) Nitrous acid.
A. Oxygen and nitrogen. ( Just think NO nitrogen oxygen )
The solution is as follows:
Important data:
*0.01 M solution = 0.01 moles <span>disodium ethylenediaminetetraacetate/ L solution
*1 L = 1000 mL
*Molar mass = 372/24 g/mol
Stoichiometric calculation:
0.01 mol/L * (1 L/1000 mL) * 500 mL * </span><span>372.24 g/mol = 1.8612 g
Therefore, you would need 1.8612 grams of </span>disodium ethylenediaminetetraacetate.
Answer:
Doubled.
Explanation:
The relationship between the temperature and the volume of a gas at a constant pressure can be described using Charles' law:
That means that the temperature and the volume of a gas are directly proportional: The higher the temperature, the higher the pressure. If one of those factors is increased twofold, the other one will be increased twofold as well.
