If you reacted 183 grams of copper sulfate with excess iron, what mass of copper would you expect to make? You may need to balan
Nezavi [6.7K]

The question does not provide the equation

Answer:-

72.89 grams

Explanation:-

The balanced chemical equation for this reaction is

CuSO4 + Fe --> FeSO4 + Cu

Molecular weight of CuSO4 = 63.55 x 1 + 32 x 1 + 16 x 4

= 159.55 gram

Atomic weight of Cu = 63.55 gram.

According to the balanced chemical equation

1 CuSO4 gives 1 Cu

∴159.55 gram of CuSO4 would give 63.55 gram of Cu.

183 gram of CuSO4 would give 63.55 x 183 / 159.55

= 72.89 grams of Cu

If 24 moles oxygen gas combined with 24 moles hydrogen gas, what would be the limiting reactant?
dsp73
Hydrogen, since in H2O there are two hydrogen atoms per one oxygen atom. So the hydrogen atoms would run out first so that there are 12 H2O molecules, where all the hydrogen is used and there are 12 oxygen atoms left over

Which formula represents a polar molecule?<br> (1) O2 <br> (2) CO2 <br> (3) NH3<br> (4) CH4
lara [203]

Answer: Option (3) is the correct answer.

Explanation:

A molecule is polar when the net dipole moment of molecule is zero. When an electronegative atom is attached to an electropositive atom then the electronegative atom pulls the shared pair of electrons more towards itself.

As a result, the movement of electrons is more towards the electronegative atom and the dipole moment becomes zero. This will also induce partial positive and partial negative charge on electropositive and electronegative atom.

On the other hand, O_{2}, CO_{2}, and CH_{4} are covalent compounds and does not have a net zero dipole moment.

Thus, we can conclude that out of the given options NH_{3}  represents a polar molecule.
