4NO + 6H20 -> 5O2 + 4NH3

Reaction 4NH3 + 5O2 4NO + 6H2O are the example of displacement reaction and redox reaction. Oxidation-reduction (redox) reaction is type of chemical reaction involves with easily transferring of two species. Oxidation-reduction reaction is chemical reaction in which the oxidation number of molecule and atom.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

do you have a formula possibly
