Answer:
it would be an alloy
Explanation:
It is a type of substance that is made by the melting of two or more elements together.
Answer:
The elements in Group 2 (beryllium, magnesium, calcium, strontium, barium, and radium) are called the alkaline earth metals (see Figure below). These elements have two valence electrons, both of which reside in the outermost s sublevel. The general electron configuration of all alkaline earth metals is ns
Based on what you have read about wind turbines and dams, how does a generator work? A loop of ______ spins in a ______ field, producing ______ current.
Answer:
Wire
Magnetic
Electric
Explanation:
The generator works on the principle of converting mechanical energy into electrical energy.
For example in a wind turbine generator, the mechanical energy is the wind that pushes the blades of the turbine directly that leads to conversion of this it's linear motion to the rotary motion required to make rotor of the generator to spin. Finally, the harder the wind pushes, the more the mechanical energy applied and consequently, the more electrical energy can be generated.
Now, all generators work because of the effect of the magnetic field moving past an electrical coil.
Thus, the movement of a magnet across a single loop of wire produces a voltage that is induced within the wire loop as a result of the magnetic field produced by the magnet.
As a voltage is induced across the wire loop, electrons begin to flow around the loop thereby generating electric current.
Answer:
2365.0 g
Explanation:
First we <u>convert 1.2 x 10²⁵ particles into moles</u>, using <em>Avogadro's number</em>:
- 1.2 x 10²⁵ particles ÷ 6.023x10²³ particles/mol = 19.9 mol
Then we <u>convert 19.9 moles of NiCO₃ into grams</u>, using the <em>molar mass of NiCO₃</em>:
- NiCO₃ Molar Mass = 118.702 g/mol
- 19.9 mol * 118.702 g/mol = 2365.0 g
