Answer:
3 moles of O2
Explanation:
From the equation you can see that the ratio of H2 to O2 is 2:1
so 6 mole of hydrogen will require 3 mole of O2
The answer is (3) An electron in the third shell has more energy than an electron in the second shell. The energy of electron will increase when number of shell increase.
Answer:
It is higher.
Explanation:
The amplitude of a wave that carries more energy is usually higher.
The energy carried by a wave is related to the amplitude in such a manner that it is proportional to the square amplitude.
Amplitude is the maximum vertical displacement of a wave moving along its path.
- Energy of wave and its amplitude are directly proportional to one another.
- If the energy of wave is doubled, the amplitude is quadrupled.
- So, the higher the energy of a wave, the more its amplitude.
Answer:
Ionic bond
Explanation:
The magnesium atom gives up 2 electrons to form a magnesium ion, Mg2+ . The two electrons are transferred to fluorine atoms to form two fluoride ions, F–.
