B) they form new substances with new properties.
I know it’s E and A
Explanation: did you count it’s exactly 28, also the electrons are not visible.
Ps: I’m in 5th grade, what grade is this, if my suggestion was correct then holy crackers.
The mass of the sample reported is 3.5465 g option e is correct.
Mass is the quantitative measure of the physical body.
The mass of the empty sample container is given as 12 g.
The mass of empty as well as sample containers is given as 15.5465 g.
Therefore, the mass of the sample will be given as :
Mass of sample = mass of a sample as well as empty containers - a mass of empty sample container
= 15.5465 - 12
= 3.5465 g
Therefore, the mass of the sample reported is 3.5465 g option e is correct.

A scientist should never let their research and experimental study be influenced by ethnicity, gender, nationality, religion or any other external factor. Any external influence such as these may lead to bias in the experimental results and yield a conclusion that is incorrect. In general, experiments should be designed in such a way that eliminates such bias.
