To find out the answer, we must know the mass percentage of Cu in the mineral chalcopyrite.
Mass percentage of Cu = molar mass of Cu/molar mass of chalcopyrite = 64/(64+56+32*2) = 34.8%.
So to obtain 210 g pure Cu, the amount of mineral need = mass of Cu/mass percentage of Cu = 210 g/34.8% = 603 g = 0.603 kg.
Answer: 1.79 x 10^-5
Explanation: The equilibrium constant of a reaction can be calculated from the quotient of the concentrations of the products over the concentrations of the reactants, with each termed raised to their respective stoichometric coefficients.
For acetic acid, this equilibrium expression is:
![Kc=\frac{[H+] [CH3COO-]}{[CH3COOH]}](https://tex.z-dn.net/?f=Kc%3D%5Cfrac%7B%5BH%2B%5D%20%5BCH3COO-%5D%7D%7B%5BCH3COOH%5D%7D)
Replacing the equilibrium concentrations given by the exercise into the expression above, the equilibrium constant, Kc will be obtained and it is found to be equal to 1.79 x 10^-5.
Answer:
1) Monochrome
2) Monocot
3) Monosaccharide
4) Monounsaturated
5) Monoxide
Explanation:
The prefix mono or mon is of Greek origin and it means single, lone or one.
From the meaning of the words we can tell that they have something in common:
1) Monochrome: This refers to an artwork, a painting or drawing that has just one color.
2) Monocot: This is a type of flowering plant that has a single embryo and a single cotyledon.
3) Monosaccharide: This is a type of simple sugar that contains one sugar unit that cannot be split.
4) Monounsaturated: This refers to a molecule that contains one double or triple bond.
5) Monoxide: This refers to a form of oxide that contains only one oxygen atom.
From the definitions above, all the words mean having only one or a single item.
That is what they have in common.
Answer:
Image result for What evidence in Side View lets you know that upwelling is happening in these locations?
Winds blowing across the ocean surface often push water away from an area. When this occurs, water rises up from beneath the surface to replace the diverging surface water. This process is known as upwelling.
