Answer: You're converting electrical energy from the wall outlet into chemical energy inside the battery, plus a bit of wasted heat energy, since battery charging is less than 100% efficient.
Explanation:
Volume = 250 mL in liters : 250 / 1000 => 0.25 L
Molarity = 0.85 M
Number of moles:
n = M x V
n = 0.85 x 0.25
n = 0.21 moles
Choice B
Answer:
Ionic bonds result from the transfer of electrons from one atom to another
Explanation:
In covalent bonds, atoms share electrons, whereas in ionic bonds atoms transfer electrons. The reaction components of covalent bonds are electrically neutral, whereas for ionic bonds they are both charged.Covalent bonds are formed between two non-metals, whereas ionic bonds are formed between a metal and non-metal.
