Answer: Is hand sanitizer more effective in killing bacteria than hand soap?
Explanation:
The most appropriate question will be questioning the effectiveness of the hand sanitizes versus soap.
The students compared the effectiveness of both the chemicals. The children must use soap and then their hand must be used as an area to get sample for microbes.
Then another group of children will use soap for washing the hand and then use hand as an area to take sample for the microbes.
The plate will show the number of colonies which will decide the effectiveness of the soap or sanitizer.

A homogeneous mixture is uniform, meaning... Neat and spread evenly throughout. The substances are fairly spread out throughout the mixture. An example my teacher used was Kool-Aid. You mix it and spread the mixture out evenly throughout the drink. A heterogeneous mixture is messy... Like a fruit salad. It's not orderly. The fruit and leaves in it are spread messily.
Also, a mixture (as you probably already know) can be separated without a means of using chemicals. You can separate things like a salads parts. Unlike, oxygen for example, which would be a compound, because you can't separate the elements within it (which I believe is hydrogen and carbon dioxide)
