The total negative charge on the electrons in 1mol of helium (atomic number 2, molar mass 4) is

The total negative charge on the electrons in 1 mol of helium is 2e⁻

The negative charge in 1 mole of a substance (here; it is helium atom) is equal to 6.022  10²³ atoms and it is also equal to 96485 C/mol

In 1 mole of helium containing 2 atomic numbers and a molar mass of 4.

The total negative charge on the electrons for 1 mole of helium can be computed as:

= 192970 C

Recall that:

The negative charge in 1 mole of helium = 96485 C/mol

∴

Numbers of negative charge in 192970 C of helium is:

= (192970/ 96485)

= 2e⁻

Explanation:

We are given that

Atomic number=2

We have to find the total negative charge on the electrons in one mole of Helium.

We know that atomic number=Proton number

Proton number=Number of electrons=2

Number of electrons in Helium=2

1 mole of Helium= atoms

We know that q=ne

Where n =Number of fundamental units

e=Charge on electron

1 e=

Using the formula

Total negative charge in 1 mole=

Hence, the total negative charge on the electrons in 1 mole of Helium=

elly's long hair:

a. if the salon only takes cash, then this isn't the problem. it doesn't matter how much she has in her checking account.   she can't get a haircut until she has the cash.

b. if she has overdraft protection, then there's no problem.   she can go ahead and write a check that her account can't cover, then sometime later, pay the bank some outrageous usury for loaning her a few bucks for a few days, but with beautiful hair.

c. if elly has some principles, and doesn't want to write a bad check, then now she has a problem.   her desire for the new hairstyle is in conflict with her honesty and integrity.

d.   if the bank will not process a check she writes, then even if she had a million $$ in her account, she couldn't use any of it.   the amount she has in her account is not the problem.   and if i may suggest, she might as well close her checking account, and put the money where it'll work for her.   it's not doing her a bit of good in a checking account, since she can't write any checks.

justin can't pay the full balance:

a. he can't even handle the credit limit he has now.   under no circumstances should he ask for a higher limit.

b.   he can ask for the grace period to be extended.   but that's no solution, the bank will almost certainly refuse anyway, and there are much better options.   he knew the rules of his credit card when he started using it.

c.   he definitely should pay the interest on the balance, plus as much of the balance as he can cover at the same time.

d.   he definitely should pay the minimum otherwise they could shut down his card.   he should also pay as much more as he possibly can.   he should also remember the awkward situation he's in, stop buying stuff on credit that he can't afford, and avoid adding any more debt.

i'd say that justin's best best option isn't on this list of choices.   what he has to do:   pay as much as he can at least the minimum payment plus as much more as he can and then avoid adding more debt.
