Let's Assign Symbols to molecules like,
C₂O₄ = X
and
H₂O = Y
Then,
K [ Co (X)₂ (Y)₂ ]
As, Potassium (K) has a O.N = +1
To neutralize, the coordination sphere must have -1 oxidation number.
So,
[ Co (X)₂ (Y)₂ ] = -1
As,
O.N of X = -2
Then
O.N of (X)₂ = -4
Also,
O.N of H₂O is zero as it is neutral, So,
[Co - 4 + 0 ] = -1
Or,
Co = -1 + 4
Co = +3
Result:
Oxidation Number of Coordination Sphere is -1 and Oxidation Number of Cu is +3.
The independent variable would be the dry ice being placed in the water/other liquid (D) and the dependent variable would be the water/other liquid the dry ice (ID) is being placed in.
Answer:
Water H2O
Explanation:
A solvent is defined as being able to dissolve other substances, the fertilizer is being dissolved in the water prior to watering the plants, therefore the water is the solvent in this case.
Metalloids share many similar properties including: They appear to be metal in appearance, but are brittle. They can generally form alloys with metals. Some metalloids such as silicon and germanium become electrical conductors under special conditions. Mark me brainliest please
4) the ice has to be heated up to above 0c first, as it is continuing to cool the water back toward 0c
5) 0.0338 kcal
(33.8/1000)
6) 1.2506 kcal
((33.8*37.0)/1000)
