Im a freshman in highschool pls how many hydrogen and oxygen are in 1 molecule of h2o2 hydrogen peroxide 2) how many atoms of aluminum sulfur and oxygen are in 1 molecule of aluminum sulfate al2(so4)3 3) how many atoms of hydrogen and oxygen are in 2 molecules of water 4) how many atoms of hydrogen and oxygen are in 8 molecules of hydrogen peroxide5) how many atoms of aluminum sulfur and oxygen are in 3 molecules of aluminum spare 6) how would you indicate 2 water molecules using chemical symbols 7) using complete sentences explain the difference between the chemical formulas shown 4 h2o and h8o4

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.
