Select the correct answer. which law represents a balanced chemical equation? a. avogadro’s hypothesis b. ideal gas law c. law of conservation of mass d. newton’s first law of motion e. newton’s second law of motion

Answer;

C. law of conservation of mass

Explanation;

The law of conservation of mass, which is one of the basic laws of chemical combination. This law states that during a chemical reaction, the total mass of the products remains equal to the total mass of the reactants.

Balanced chemical equations must obey the Law of Conservation of Mass that states that matter cannot be created or destroyed, it is conserved. Atoms are never lost or gained in chemical reactions, they are rearranged. The mass of the reactants must equal the mass of the products.

c. law of conservation of mass

Explanation: PLATO USERS

e) none of the above answers are correct

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.
