What is the oxydation state for S in SO4-2?
The oxydation state for S in (SO4)2- is 6.
How many Co atoms are there in 230 grams of CoCl2?
To answer this question you need the molecular weight of CoCl2. CoCl2 molecular weight is 129.84 g/mole 230g CoCl2 divided by the molecular weight 230 g / 129.84 g/mole = 1.77 moles of CoCl2 Multiply the moles by Avagodro's number 1.77 mole * 6.022 X 1023 molecules/mole = 1.07 X 1024 molecules of CoCl2
Which halogen naturally exists in positive oxidation no?
which halogen naturally exit in + ve oxydation state
Why is CoCl2 in Hygrometers?
CoCl2 is used in hygrometers due to its color-changing abilities. It can help calculate the levels of humidity in the air.
What is the oxidation state of sodium in NaHCO3?
I'm pretty sure it's -2 because everywhere i look i find the chemical formula as being NaHCO3 and if you add up those oxidation numbers then you get -2.
What is the oxydation state for S in SO4-2?
The oxydation state for S in (SO4)2- is 6.
