in the chapter test of ths chapter in question no 3 all statements are correct and i was confused so i had opted for option b which is that in pure air carbon monoxide,sulphur dioxide and nitrogen oxide whilethey are saying my answer is wrong and option c which includes statement 1 and3 are correct and there were no options that all statements are true!!!!
What should be the result of the following activity?
Open a water rap. Adjust the flow so that it forms a thin stream, Charge a refill. Bring it near the water stream. Observe what happens. Write a short report on the activity.
Please help me. When I do this activity nothing happens. I ensure that the water flow is slow and the refill is charged.
sorry in the last question it will not be fission but fusion.
Why is coal used as a reducing agent in industries?
what is chain reaction and what is fractional distillation?
