100 g of manganese dioxide reacts with 300 g of hydrochloric acid in the reaction shown below.
MnO2 + 4HCl -> MnCl2+ 2H2O + Cl2
(Use the following molar masses: MnO2= 86.9g/mol HCl = 36.5g/mol ; MnCl2= 125.8g/mol; H2O= 18.02g/mol and Cl 2 =70.9 g/mol.

What should be the length of an ideal solenoid consisting of 1250 turns for
the magnetic field in its interior to be 0.025 T?
A current of 2.0 A is flowing
through the solenoid.
Two parallel wires are separated by a distance of 0.05 m. Wire 1 carries a
carries current of 12.0 A. Wire 2 carries a current of 6.0 A flowing in the
opposite direction as shown in the illustration.
Find the
(a) magnitude and
direction of the magnetic field created by wire 1 at wire 2,
(b) force exerted
by wire 1 on the 2.0 m long section of wire 2, and
(c) force exerted by wire 2
on wire 1.
