Okay so we know that pOH + pH = 14, so if pOH is 0.253 the pH would be 13.747.
<span>And pH = -log [H+], so [H+] = 10^(-pH) -->This is just the antillog... </span>
<span>so [H+] = 1.791e-14, which would make sense for the strongly basic solution (so B is the correct answer) </span>
<span>Hope this helps...</span>
A) Double replacement
Because the reactants switch when they become products
Answer:
9.6 t
Explanation:
You want to convert tablets ⟶ tons
I would use the conversion sequence:
tablets ⟶ milligrams ⟶ grams ⟶ kilograms ⟶ pounds ⟶ tons
===============
1 tablet = 500 mg Convert tablets to milligrams
Milligrams = 85 × 10⁶ × 500/1
Milligrams = 4.25 × 10¹⁰ mg
===============
1000 mg = 1 g Convert milligrams to grams
Grams = 4.25 × 10¹⁰ × 1/1000
Grams = 4.25 × 10⁷ g
===============
1000 g = 1 kg Convert grams to kilograms
Kilograms = 4.25 × 10⁷ ×1/1000
Kilograms = 4.25 × 10⁴ kg
===============
I kg = 2.205 lb Convert kilograms to pounds
Pounds = 4.25 × 10⁴ × 1/2.205
Pounds = 1.93 × 10⁴ lb
===============
1 t = 2000 lb Convert pounds to tons
Tons = 1.93 × 10⁴ × 1/2000
Tons = 9.6 t
