The question is incomplete.

The complete question probably is

The pH scale for acidity is defined by pH = − log₁₀[H⁺] where [H⁺] is the concentration of hydrogen ions measured in moles per liter (M). A solution has a pH of 2.55. Find the hydrogen ion concentration.

Answer: -

0.003 M

Explanation: -

pH = − log₁₀[H⁺]

Thus the hydrogen ion concentration [H⁺] = 10^{-pH}

= 10^{-2.55}

= 0.003 M

A solution has a pOH of 8.7 so what is the pH of the solution? Is the solution acidic, basic, or neutral?
RSB [31]
PH + pOH = 14

pH = 14 - pOH

pH = 14 - 8.7

pH = 5,3

This solution is <u>acidic</u>.

If pH<7 - acidic
If pH=7 - neutral
If pH>7 - basic

2Al(s)+Fe2O3(s) → Al2O(s)+2Fe(s) with a delta H=-847 KJ.
Scrat [10]

∆H for given reaction -847kJ

  • As it's negative reaction is exothermic

So

2 mol of Al releases 847KJ heat

4 mol Al releases

  • 2(847)
  • 1694KJ

∆H=-1694KJ
