Answer:
each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
"some elements have only one stable isotope"
Explanation:
Answer:
The answer is B (25%)
Explanation:
I think the answer is this because it's the smallest value in the options, and if you choose 0% the answer would be wrong.
31.79 g Cu / 63.5 g/mol Cu ---> 0.5
0.5 * (2/1) ---> 1
1 * 107.9 g/mol Ag
107.9 grams
Chlorocyclohexane is a substance synthesize through the reactants cyclohexane and chlorine. This has a chemical formula of C₆H₁₁Cl. This is a colorless liquid with suffocating odor and is used as an intermediate for the rubber chemicals and agrochemicals. Because it is comprised of one cyclohexane with the chloride replacing one of the H⁺ then, the ratio between the cyclohexane and the chlorine should be 1:1.
Answer:
0.225M of Fecl3
Explanation:
No of mole=mass/molar mass
Molar mass of fecl3= 162g/Mol
No of mole= 10/162= 0.062mol
No of Mol = concentrate × volume
Concentration= n/V = 0.062/0.275
C= 0.225M of FeCl3
