Hydrogen + Oxygen = Water

H2+O2= H2O

But that's not right because you have to balance it

So it's 2H2+O2=2H2O

My chem teacher said that water will get you full marks although they might allow hydroxide, depends on the mark scheme. Hydroxide is not wrong however its not the best answer! Its like saying 2+2= 6-2, although its right it =4 and thats the better way to say it!

I circled neon, and I also balanced it right, hooray!

Lots of people in my school missed out the first question, completely forgot to complete the energy shell diagram...

I thought the paper was awfully worded, especially the bromine question! It was awful...

So, was it basically, that the higher number of bromine droplets that were needed, the MORE unsaturated the oil was? Or the opposite, can someone clarify this...

Thanks!
