Thanks for your help with this
word equation is
sulfer dioxide + oxygen -----sulfer trioxide
Using chemical symbols, write a balanced equation for the above reaction using the lowest possible whole number coefficents, include after the chemical formulae the symbol state of the compound.
The other query is
A island is said to be 65Ma old, the distance (as the crow flies) of the island to the volcanic hot spot of Hawaii is currently about 4.2 x 10 3Km (the 3 is the power of ten) (sorry I couldnt type it any other way
It you assume that the plate had moved in one direction only this distance would give an indication of the speed of movement of the plate over the last 65Ma , Calculate this apparent speed of the Pacific Plate.
If I need another credit just let me know don't know how much a credit entitles me to.
I thank you very much in advance for your help, I think I have it worked out, but your confirmation one way or the other would help
2SO2 (g) + O2 (g) ---> 2SO3 (g) is the required balanced equation.
You can see that, the number of atoms is the same on both ...
The solution provides and easy to follow explanation of the concepts and gives all mathematical steps wherever necessary.
