How many moles of copper are needed to react with sulfur to produce 0.25 moles Ol
Tems11 [23]

Answer:

                       0.50 moles of Cu

Explanation:

                    The balanced chemical equation for given synthetic reaction is,

                                          2 Cu + S → Cu₂S

According to balance chemical equation,

                  1 mole of Cu₂S is produced by  =  2 moles of Cu

So,

          0.25 moles of Cu₂S will be produced by  =  X moles of Cu

Solving for X,

                      X  =  0.25 mol × 2 mol /  1 mol

                      X  =  0.50 moles of Cu

Hence, as the molar ratio of Cu to Cu₂S is 2:1 hence, to produce 0.25 moles of Cu₂S we will need 0.50 moles of Cu.

How do you Calculate the molarity of 250 ml of solution in which 2.7 g of MgCl2 are dissolved
IRINA_888 [86]

Answer:

Molar mass of MgCl2 is 95 g/mol

Mg = 24 g/mol and Cl = 35.5 ×2 = 71 g/mol

moles = mass given/ molar mass

= 2.7/95 = 0.028 mol

volume = 250/1000 = 0.25 dm3 (ml is the same as dm3)

molarity of MgCl2 = moles/volume

= 0.028/0.25

= 0.112 mol/dm3

How is earth's mantic field similar to that of a bar magnet
Alika [10]

Answer:The outer core of the Earth contains a lot of iron in a molten state. As the Earth spins this molten iron moves and creates the Earth's magnetic field. The Earth behaves as if there is a huge bar magnet at its centre. The shape of the field around the Earth is very similar to the field around a bar magnet
