Answer:
the second one
Explanation:
heterogeneous is the mixture that we can see the difference between it's components crearly by eye do it will be the water and pool
Answer:
See explaination
Explanation:
Since X is more reactive than Y
=> X is oxidized to X2+ and Y2+ is reduced to Y
Overall cell reaction is:
X(s) + Y2+(aq) => X2+(aq) + Y(s)
please kindly see attachment for further solution.
Remember, electronegativity is a measure of how strongly an atom bonds to its electrons i.e. the likelihood of an atom to attract an electron.
If you think about it, the less electron shells the atom has, the stronger the electrons will bond to the atom. Furthermore, the greater the atom's atomic mass, the more the electrons will be attracted to it.
Knowing this, we're looking for the element that is farthest to the left and bottom of the periodic table. So Francium (Fr) will be your answer.
Explanation:
Since, it is given that density is 1.16 grams per milliliter and molar mass of copper sulfate pentahydrate is 249.68 g/mol.
Now, as we known that density is the amount of mass present in a unit volume.
Mathematically, Density =
Hence, calculate the volume as follws.
Density =
1.16 g/mL =
volume = 215.24 mL
As, 215.24 mL can dissolve in 249.68 g/mol of complex. So, in 100 mL volume amount dissolved will be calculated as follows.
= 116 grams
Thus, we can conclude that 116 grams of copper sulfate pentahydrate that will dissolve in 100 g of water at 0.
