1000dm = 0.1 km
The picture below is proof that it is correct.
Answer: 40 + 2x14 + 6x16 = 164g/mole
54.3g x [1mole / 164g] = 0.331moles
355mL x 1L / 1000mL = 0.355L
molarity = 0.331moles / 0.355L =
00
Explanation:
Answer:
Rise in charge reduced the size due to rise in attraction between electron and nucleus.
Explanation:
Ion of magnesium is smaller than the atom of magnesium. As the nuclear charge increases, the attraction of electron to the nucleus increases in charged ions form of any element. Due to this increase in charge of magnesium ion, the size of ion reduces
No. of electrons in Mg = 12
No. of proton in Mg = 12
Where as
No. of electrons in Mg2+ = 12
No. of proton in Mg2+ = 10
To answer the question "What is amplitude?", first look at the context of the question. A poem is also given before the questions which discusses about sound waves. Therefore, considering the context above, amplitude is the height of the wave.
