Answer:

Reaction

Mg+H2SO4 ----》MgSO4+H2

so calculate the moles of magnesium first

moles of magnesium = given mass of mg/molar mass of magnesium

moles = 4/24.30

moles = 0.1646

One mole of magnesium produces one mole of magnesium sulphate

so 0.1646 moles of mg will produce 0.1646 moles of MgSO4

Mass of MgSO4 = 0.1646× 120.366

MgSO4 = 19.81 gm

conclusion the mass of magnesium sulphate that would be obtained from 4g of

magnesium is 19.81 gm!!

I d k it's right or wrong but i tried :)

Why is graphite used for electrodes?

scZoUnD [109]

Answer:

Graphite is an electrical conductor, hence useful in such applications as arc lamp electrodes. It can conduct electricity due to the vast electron delocalization within the carbon layers (a phenomenon called aromaticity). These valence electrons are free to move, so are able to conduct electricity.

Nitrogen is a group 15 element. What does being in this group imply about the structure of the nitrogen atom?

Yanka [14]

Answer:

D. Nitrogen has 5 valence electrons.

Explanation:

Nitrogen is an element in group 5A of the periodic table. Elements in group 5A all contain just 5 valence electrons. (Electrons in the outer shell).

**Elements are organized into these groups in a periodic table based on the number of valence electrons which determines their charge. (Does not apply to transition metals)

Help please-

Answer:

Oxygen and Carbon are in the non-metal section. Both are in 2nd period while Carbon is in group 4A and Oxygen is in group 6A.

Oxygen has more valence electrons than carbon. I wish I could give you a more accurate explanation why on paper, but all you need to do is count the electrons on the largest shell.

Here's the orbital notation of Carbon: 1s^2 2s^2 2px^1 py^1

Carbon's largest shell is 2. Count the electrons on shell 2, and you get 4 valence electrons.

Orbital notation of Oxygen: 1s^2 2s^2 2px^2 py^1 pz^1

Oxygen's largest shell is 2. So, like with carbon, count the electrons on the largest shell. You get 6.

There is a way easier way of interpreting this where you do not even have to write the orbital notation. I wish I can explain, but just know the periods and the group numbers.
