The number of Zn particles (atoms of Zn ) in the first sample, and Zn ions are going to be the same,
Also mass of Zn are going to be the same, because of electrons are too small, and would not have influence on mass.
I don’t know but look up the ph of ammonia and if it is below 7 then it is yellow and if it is above 7 then blue
Hi!
Fuel-cell cars only release water and heat in the atmosphere.
Since they are only run by oxygen and hydrogen to produce electricity in the motor, they don't emit carbon dioxide or greenhouse gas as what other people think.
Basically, automotive engineers and scientist classified them as zero-emission.
Answer:
gravitation force is your answee
The relative abundances of the isotopes of an element is determined using mass spectrometry. A mass spectrometry isotope distribution graph is needed as shown in the picture. This is for the isotopes of Zirconium. The x-axis is the individual mass, while the y-axis is the relative abundance. For this example, the atomic weight of Zirconium is calculated as:
Atomic weight = 90 amu(50%) + 91 amu(11%) + 92 amu(18%) + 94 amu(19%) + 96 amu(2%) = 91.35 amu
