If you were burning candles in a science lab, what risks can happen?

The characteristic of two different types of reactions are shown below. reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of and element. which statement is true about the atoms of the elements that participate in the two reactions? a: their identity changes in both reaction a and b. b: their identity changes in reaction a but not b. c: their identity changes in reaction b but not a. d: their identity remains the same.

Determine the reaction and balance the following equations urgent due in the morning

Measurements that have similar values are: a. usually accurate b. sometimes accurate c. always accurate d. never accurate
