I'm pretty sure that it's either 83.2% or 91.4%
Tungsten has the highest melting point (6192°F) of all metals in their pure form.
Answer:
A. the ration is 2 to 3, 2Al + 3H2SO4 has the same balance as 18Al + 3H2SO4
2/3 = 18/27
B. Doesn't need an explanation other than the work you did to balance it.
The krypton-83 isotopes below is formed when rubidium-83 undergoes electron capture.
What is isotopes?
isotopes are defined as atoms with a constant number of protons but a variable number of neutrons. Despite having different masses and hence having different physical qualities, they have nearly identical chemical properties.
What is stable nuclide?
Since stable nuclides are not radioactive, they do not spontaneously decay into radioactive elements as happens with radionuclides. They are commonly referred to as stable isotopes when such nuclides are discussed in connection to particular elements.
The electron capture process will turn rubidium-83 into krypton-83. When a proton in the nucleus catches an inner electron and creates a neutron, this process is known as electron capture.
Therefore, krypton-83 isotopes below is formed when rubidium-83 undergoes electron capture.
