Answer:

Faraday's constant will be smaller than it is supposed to be.

Explanation:

If the copper anode was not completely dry when its mass was measured, mass of the copper must be heavier than it should have been. Hence, the calculated Faraday’s constant would be smaller than it is supposed to be since when calculating Faraday’s Constant, the charge transferred is divided by the moles of electrons.

Find the molarity of a 500 L solution that contains 10 moles of fluorine.
deff fn [24]

<u>Given </u><u>:</u><u>-</u>

  • Number of moles = 10
  • Volume of solution = 500L

<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>

  • Molarity of the solution .

<u>Solution</u><u> </u><u>:</u><u>-</u>

As we know that ,

\longrightarrow Molarity (M )=\dfrac{Number\ of \ moles \ of \ solute }{Volume\ of \ solution\ (in \ L) }

Substitute ,

\longrightarrow M =\dfrac{10}{500L}

Simplify,

\longrightarrow M = \dfrac{1}{50}

Convert into decimal ,

\longrightarrow \underline{\underline{ M = 0.02 \ mol \ L^{-1}}}

This is the required answer .

Which method of heat transfer causes magma to circulate in the mantle?
andrezito [222]

Answer:

i hope this helps

Magma in the Earth's mantle moves in convection currents. The hot core heats the material above it, causing it to rise toward the crust, where it cools. The heat comes from the intense pressure on the rock, combined with the energy released from natural radioactive decay of elements.

What are the possible values of n and ml for an electron in a 5d orbital?
liberstina [14]

Answer:

The answer to your question is n = 5, l = 2, m can be -2, -1, 0, 1 or 2

Explanation:

Data

orbital = 5d

values of n, l, m

Process

1.- Determine the value of n

n is the coefficient of the orbital, in this problem n = 5

2.- Determine the value of l

l takes values depending in the sublevel of energy,

if the sublevel is s  then l = 0

                           p          l = 1

                           d          l = 2

                           f           l = 3

For this problem l = 2

3.- Determine the value of m

when l = 2, m takes values of -2, - 1, 0, 1 or 2
