Answer:
One factor that affects that affects the direction of the current is the direction of motion of the wire
Explanation:
According to Fleming's right hand rule when a conductive wire which is within a circuit is moved through a magnetic field, due to Faraday's law of electromagnetic induction an electric current is induced in the wire such that the direction of motion of the wire, the direction of the magnetic field and the direction of the electric current are perpendicular to each other such that if the right hand has the thumb middle finger and the index finger held perpendicular to each other
The motion of the wire being in the direction of the wire
The first or index finger points in the direction of the magnetic field
The middle finger points in the direction of the induced electric current
Therefore, the direction of the the current depends on the direction of motion of the wire.
Answer:
35.94 g of NaCl
Explanation:
First write a balanced chemical reaction.
2Na + Cl₂ --> 2NaCl
(Note that the Cl has a subscript of 2 because it's diatomic)
Then, set up an basic stoichiometry equation using one of the given masses of the reactants. I chose chloride.
The masses were acquired from the periodic table. (compound's mass requires the addition of individual element's masses) Also, the number of moles per reactant or product is based on the coefficient from the chemical reaction. I can't show this, but note that the units do cancel out so all that's left is grams of sodium chloride, which is what we were looking for.
Explanation:
Objects or substances with their density greater than that of water will sink in it whiles those less than water will float on it.
From the question the object has a density of 3.4 g/mL.
Since it's density is greater than that of water the object will sink.
Hope this helps you
A catalyst is a compound that accelerates a chemical reaction without getting used up in the process.
Un catalizador es un compuesto que acelera una reacción química sin ser agotado en el proceso.
