I believe it would be a compound.
Answer:
2.67 × 10⁻²
Explanation:
Equation for the reaction is expressed as:
CaCrO₄(s) ⇄ Ca₂⁺(aq) + CrO₂⁻⁴(aq)
Given that:
Kc=7.1×10⁻⁴
Kc= ![[Ca^{2+}][CrO^{2-}_4]](https://tex.z-dn.net/?f=%5BCa%5E%7B2%2B%7D%5D%5BCrO%5E%7B2-%7D_4%5D)
Kc= [x][x]
Kc= [x²]
7.1×10⁻⁴ = [x²]
x = 
x = 0.0267
x = 
The answer is homogeneous mixture. It is a mixture which has uniform composition and properties all throughout. Mixtures can be separated by physical processes. Mixtures are systems that consist of two or more substances which are mixed but not chemically combined.
Answer:
A. Ernest Rutherford
B.Bohr
C. Eugen Goldstein
D.. Santiago Ramon y cajal
E.john Dalton
F.isobars - a line drawn on a weather map connecting points of equal pressure is called isobars.
example.. argon 40
potassium 40
.two differences between isobars and isotopes.
isobars are those elements which have different atomic number but the same mass number. while isotopes are those elements having the same atomic number and different mass number..
two uses of isotopes.
uranium 235 - for nuclear fission and as fuel in unclear reactors.
# an isotope cobalt - used In the treatment for cancer
# an isotope iodine - used in treatment of goiter.
