4 0
Molar mass MgSO₄.7 H₂<span>O = 246.52 g/mol

number of moles :

11.0 / 246.52 => 0.0446 moles

Molar mass MgSO</span>₄ = 120.4 g/mol

Mass of <span>anhydrous magnesium sulfate :
</span>
( 0.0446 x 120.4 ) => 5.36984 g

hope this helps!

Plz help me with this:
skad [1K]

Answer:

We are to write the orbital notation and electronic configuration of sulfur and iron.

The orbital notation shows the filling of electrons into orbitals or sublevels.

Electron configuration  shows the distribution of electrons into shells;

       Number of electrons     Electron configuration     Orbital notation

If a molecule contains two carbon atoms and four hydrogen atoms, what can you conclude about the bond between the carbon atoms?
g100num [7]
For the given question above, I think the bond between the carbon atoms is a double bond. <span>2 carbon atoms and 4 hydrogen atoms will give an ethene, which has a C=C bond between carbon atoms. I hope this is the answer you are looking for.</span>

List the bonding pairs H and I; S and O; K and Br; Si and Cl, H and F; Se and S; C and H in order of increasing covalent charact
stellarik [79]

Answer:

1. (S,O) < (Se,S) < (C,H) = (H,I) = (H,F) < (Si,Cl) < (K,Br)

Explanation:

The covalent character always increases down the group, this is because ionic character decreases down the group and also electronegativity.

In the same way, Covalent character always decreases across a period because electronegativity increases across a period.

The higher the electronegativity values between the two atoms, the more ionic it will be.
