Answer:
Explanation:
0.76 V
The voltmeter shows that the standard cell potential of a galvanic cell consisting of a SHE and a Zn/Zn2+ couple is E°cell = 0.76 V.
Mole ratio:
MgCl₂ + 2 KOH = Mg(OH)₂ + 2 KCl
2 moles KOH ---------------- 1 mole Mg(OH)₂
4 moles KOH ------------------- moles Mg(OH)₂
moles Mg(OH)₂ = 4 x 1 / 2
= 2 moles of Mg(OH)₂
molar mass Mg(OH)₂ = 58g/mol
mass of Mg(OH)₂ = n x mm
mass of Mg(OH)₂ = 58 x 2
= 116 g of <span> Mg(OH)₂</span>
hope this helps!
Explanation:
if you can tell me which law you are using i can solve it. Also I have plenty of notes on this subject of Gas Laws that I believe can help you, if you send me ur email I can send them all to you tomorrow.

Answer:
The electricity that flows to our homes is generated in the power station from here it flows through large transmission line which carry it to substations finally distribution carry electricity from substations to homes schools etc
