I think the correct answer among the choices presented above is option A. An ore is rock that contains a mineral or metal with economic usefulness. Examples are copper ore, gold ore and iron ore. These ores are being extracted from the Earth by mining.
PV = nRT
P is pressure, V is volume, n is number of moles, R is the gas constant, T is temperature in K
(2.85 atm)(12.5 L) = (n)(.08206)(27 C + 273)
n = 1.45 moles x 35.45 grams / mol Cl2 = 51.3 grams
Answer:
The answer is 529.6 g
Explanation:
I took the test and somehow got it right :0 but yea this is the correct answer. I hope this helps :)
Answer: (2)react completely in the reaction
limiting reactant determines the number of moles in a chemical reaction
excess reactant is the reactant with an excess number of moles
Mitosis has one round of cellular division and genetic separation whereas meiosis has two rounds. The two processes are also different because in mitosis the daughter cells are exactly identical to the parent cells compared to meiosis where the daughter cells are not genetically identical to the parent cells
Hope this helped
