Answer:
Electrons are moved through a magnet, creating a current. That current interacts with a circuit, moving the conductor in the orientation of the field.
Explanation:
Electro magnetic fields are used to create electric current by the movement of electrons. When a coil of wire is wrapped around a magnet it pushes electrons and they flow through a magnet to create current. This current interacts with circuit to move conductor.
Answer:
Too much iodine can be harmful if you don't need it. You don't need to take iodine (supplements) if you already have a varied and balanced diet.
Explanation:
Iodine is already contained in table salt so you don't need to add any more.
Answer:When a bus suddenly starts, the passengers sitting or standing in the bus tend to fall backward. This is due to inertia of rest and can be explained as follows: when the bus suddenly starts, the lower part of the body of the passenger which is in contact with the bus moves along with the bus while the upper part of the body tends to retain its state of rest due to inertia. As a result, the passenger falls backward.
Explanation:
The given chemical equation is:
On balancing the equation we get,
Calculating enthalpy of formation of this reaction from the standard heats of formation of the products and reactants:
Δ
=[(-1669.8kJ/mol)+ {3* (-909.27 kJ/mol)}]-[(-3442kJ/mol)+{3*(-285.8 kJ/mol)}]
=[(-4397.61kJ/mol)]-[(-4299.4kJ/mol)]
=-98.21kJ/mol
Total enthalpy change when 15 mol of reacts will be=
