Answer:
1.70
Explanation:
The molar mass of perchloric acid is 100.46 g/mol. The moles corresponding to 484 mg (0.484 g) are:
0.484 g × (1 mol/100.46 g) = 4.82 × 10⁻³ mol
4.82 × 10⁻³ moles are dissolved in 240 mL (0.240 L) of solution. The molar concentration of perchloric acid is:
4.82 × 10⁻³ mol/0.240 L = 0.0201 M
Perchloric acid is a strong monoprotic acid, that is, it dissociates completely, so [H⁺] = 0.0201 M.
The pH is:
pH = -log [H⁺] = -log 0.0201 = 1.70
No it is not, texture is a physical property

It is ionic. Magnesium is a metal, so it would make a positive ion (cation) with a charge of +2. The c2h3o2, or acetate, is a common polyatomic ion with a charge of -2. Because one charge is positive and one is negative, the bond will be ionic.
A closed circuit will light the bulb because electricity flows through it.
But on the other hand in an open circuit there is no flow of electricity current hence no light is produced
