Answer:
The pH of the solution will be 3
Explanation:
The strength of acids is determined by their ability to dissociate into ions in aqueous solution. A strong acid is any compound capable of completely and irreversibly releasing protons or hydrogen ions, H⁺. That is, an acid is said to be strong if it is fully dissociated into hydrogen ions and anions in solution.
Being pH=- log [H⁺] or pH= - log [H₃O⁺] and being a strong acid, all the HClO₃ dissociates:
HClO₄ + H₂O → H₃O⁺ + ClO₄-
So: [HCLO₄]= [H₃O⁺]
The molar concentration is:
The molar mass of HClO₄ being 100 g / mole, then if 100 grams of the compound are present in 1 mole, 0.025 grams in how many moles are present?
moles of HClO₄= 0.00025
Then:
![[HClO_{4}]=\frac{0.00025 moles}{0.25 L}](https://tex.z-dn.net/?f=%5BHClO_%7B4%7D%5D%3D%5Cfrac%7B0.00025%20moles%7D%7B0.25%20L%7D)
![[HClO_{4}]=0.001 \frac{ moles}{ L}](https://tex.z-dn.net/?f=%5BHClO_%7B4%7D%5D%3D0.001%20%5Cfrac%7B%20moles%7D%7B%20L%7D)
Being [HCLO₄]= [H₃O⁺]:
pH= - log 0.001
pH= 3
<u><em>The pH of the solution will be 3</em></u>

Natural gas is primarily composed of methane (CH4)
Natural gas is a naturally occurring hydrocarbon mixture which is primarily composed of Methane(CH4), but it also contains ethane,propane and heavier hydrocarbon. In addition it contain small amount of nitrogen, carbon dioxide,hydrogen sulfide and traces amount of water.
All oxayacids have cations so no need to name the cation (H+) If name of polyatomic anion ends in -ate change to -ic for acid and if it ends with -ite change to -ous for acid
example:
ion nitrate is called nitric acid
ion nitrate is called nitrous acid
The early hypothesis of Alfred wegener was based on observations that suggested continents were once joined together. later the theory of plate tectonics explained why large pieces of earths surfaces moves around and how many of earths features form.
but i this case c. continental drift and plate tectonics
Answer:
If we assume that there will be enough Hydrogen for the reaction to occur, then there will be 8 moles of NH
Explanation:
The balanced equation will look like this:
4N2 + 4H2 -> 8NH
