Answer:
5.195 ml
Explanation:
Dissociation of HCl yields;
HCl(aq) ⇄ H⁺(aq) + Cl⁻(aq)
∴ [HCl] = [H⁺] = [Cl⁻]
pH = 1.9
= -log[ H⁺]
= 
= 
= 0.01258 M
Moles of HCl = number of mole × volume
= 0.01258 × 4.80 L
= 0.06042 mole
Mass of HCl = number of moles of HCl × Molar mass of HCl
Mass of HCl = 0.06042 mol × 36.5 g/mol
Mass of HCl = 2.205 grams
Also, given that the density = 1.179 g/mL
Mass of HCl in the solution = 36% of the density
i.e 
= 0.4244 grams
Volume of a concentrated HCl solution needed can now be determined as;
= 
= 
Answer:
Explanation:
Avogadro's number, 6.022 * 1023 is the number of things in one mole. The question indicates that there is 1 mole of H2. Thus there are 6.022 * 1023 molecules of H2
The number of electrons. The valence (outer) shell is particularly important.
I cant see the question im sorru
When water chemically combines with carbon dioxide, a Carbonic acid is formed.
<u>Explanation</u>:
- Carbon dioxide responds with water in a solution to form a weak acid, carbonic acid. Carbonic acid disassociates into hydrogen particles and bicarbonate particles. The hydrogen particles and water respond with the most basic minerals modifying the minerals.
-
Carbon dioxide and the other atmospheric gases disintegrate in surface waters. Dissolved gases are in equilibrium with the gas in the atmosphere. Carbon dioxide responds with water in a solution to form the weak acid, carbonic acid. Carbonic acid disassociates into hydrogen particles and bicarbonate particles.
-
The hydrogen particles and water respond with the most basic minerals altering the minerals. The results of enduring are prevalently clays and soluble particles, for example, calcium, iron, sodium, and potassium. Bicarbonate particles additionally remain in solution; a remnant of the carbonic acid that was utilized to weather the rocks.
