Answer is: formula of the complex is [Cr(NH₃)₂(SCN)₄<span>]</span>⁻<span>.
This complex has negative charge (-1) because chromium (central atom or metal) has oxidation number +3, first ligand ammonia has neutral charge and second ligand thiocyanate has negative oxidation number -1:
+3 + 2</span>·0 + 4·(-1) = -1.
Answer:
After measuring the solute, Carl should first dissolve the solid in a small amount of DI water before diluting to the total volume.
Explanation:
To ensure that all the solute dissolves in the solution, first dissolve the solid in less than the total volume of solution needed.
Answer:
Because it does not have to
Explanation:
Why because when you blow at it it might move it does not change it's shape because it is a solid
Answer is Neap tides I believe.
1 carat -------------- 200 mg
44.4 carat ---------- ( mass diamond )
mass = 44.4 x 200 / 1
mass = 8880 mg
1 g ------------------------ 1000 mg
( mass in grams) --------- 8880 mg
mass in grams = 8880 x 1 / 1000
mass in grams = 8880 / 1000
= 8.88 g
