Dont they have like different types of reactions and how they fit together?
There are two main areas of an atom, the electron cloud and the nucleus
First, let's talk about the atom's nucleus. The nucleus is in the middle of the atom. The nucleus contains neutrons (particles with no charge) and protons (positively charged protons). The number of protons is constant in every atom of the same element, meanwhile the number of neutrons is not. The atomic number of an element describes the amount of protons in a atom of that same element and it is fixed.
The electron cloud, on the other hand, is a predicted zone that's used to roughly estimate where the electrons are within the atom. Electrons are said to have no fixed orbit.
I don't want to get too in depth and make you confused so I hope this helped!
If the ball is dropped from a higher height than the feather their rates of displacement (acceleration) could match.
Answer:
No.
Explanation:
No, these metals are not uniformly distributed in the lithosphere, they are present some special regions of earth. Chromium ore is found in many places including South Africa, India, Kazakhstan and Turkey. Cobalt ore deposits are present in the regions of Congo, Canada, Australia, Zambia and Brazil. China, Africa, Australia and Gabon are the regions on the earth where manganese metal is present in large quantity.
Answer:
2.3 * 10^-5
Explanation:
Recall that the solubility of a solute is the amount of solute that dissolves in 1 dm^3 or 1000cm^3 of solution.
Hence;
Amount of calcium oxalate = 154 * 10^-3/128.097 g/mol = 1.2 * 10^-3 mols
From the question;
1.2 * 10^-3 mols dissolves in 250 mL
x moles dissolves in 1000mL
x = 1.2 * 10^-3 mols * 1000/250
x= 4.8 * 10^-3 moldm^-3
CaC2O4(s) ------->Ca^2+(aq) + C2O4^2-(aq)
Hence Ksp = [Ca^2+] [C2O4^2-]
Where;
[Ca^2+] = [C2O4^2-] = 4.8 * 10^-3 moldm^-3
Ksp = (4.8 * 10^-3)^2
Ksp = 2.3 * 10^-5
