Ethanol is polar because the oxygen atoms attract electrons because of their higher electronegativity than other atoms in the molecule. Thus the -OH group in ethanol has a slight negative charge. Ammonia (NH3) is polar. Sulfur dioxide (SO2) is polar.
Answer:
A- beryllium
B- calcium
C- magnesium
Explanation
NOTE: all element in group 2 have 2 balance electrons
First let’s start with B- number of electrons= number of protons which is equal to the atomic number. therefore, the answer is calcium as it’s atomic number is 20
C- magnesium will have three energy levels considering it has 12 electrons (2,8,2).
A- beryllium is the lightest one in group 2 as it has the atomic mass of 9.0122.
That would be anaerobic fermentation
I hope I've helped!
Answer:
1.- The energy of a wave will increase the frequency due to the increase in the speed of the wave.
2.- The wavelength will increase if the energy of the wave increases, due to the area that is expand.
3.- A wave with a higher frequency will have faster speed to move.
Explanation:
Wavelength of a wave is due to the speed and the energy that the wavelength carry, so if the energy increases, this quantity of energy need to distribute or in the wavelength or in the frequency, to conduct the wave with a bigger amount of energy.
