The equation for molarity is molarity equals moles divided by liters of solution. Knowing this, it's just simple algebra of 2 moles divided by .5 liters, equaling 4M (M standing for molarity).
Answer:
It causes more creases and wrinkles making it hard to get a clean cut.
Explanation:
After ripping off sheets of aluminum foil from a roll, you may need to cut various shapes for your project. Aluminum foil easily creases and wrinkles, making it difficult to cut into smaller or more designs.

Oxidation half reaction :-
<span>Cu --------> Cu2+ + 2e- ...(1) </span>
<span>this is the balanced oxidation half reaction </span>
<span>b) reduction half reaction :- </span>
<span>NO3- -----------> NO </span>
<span>balance oxidation no. </span>
<span>NO3- + 3e- --------> NO </span>
<span>balance charge by adding H+ </span>
<span>NO3- + 3e- + 4H+ ---------> NO </span>
<span>now balance O and H atoms by addin H2O... </span>
<span>NO3- + 3e- + 4H+ ---------> NO + 2H2O....(2) </span>
<span>this is balanced reduction half reaction </span>
<span>multiply (1) by 3 and (2) by 2 and add </span>
<span>3Cu ---------> 3Cu2+ + 6e- </span>
<span>2NO3- + 6e- + 8H+ ---------> 2NO + 4H2O </span>
<span>--------------------------------------... </span>
<span>6e- will cancel out fom both sides... </span>
<span>3Cu + 2NO3- + 8H+ ---------> 3Cu2+ + 2NO + 4H2O </span>
