A student wants to find out if the amount of bleach has an effect on stain removal.
Step2247 [10]

Answer:

The second option.

Explanation:

We're trying to test the amount of bleach that has an effect on the stain so that is the altered variable.

The 2nd option uses different amounts of bleach to clean the same amount of stain.

If you choose the other options, people can argue that the bigger stain would be harder to clean with one cup of bleach, whereas the small stain gets two cups or the other way around.

It's not an effective way to see if the amount of bleach has an effect on stain removal.

What change to the following molecule's structure would result in a saturated fat?
NemiM [27]

Answer:

It needs to gain a Hydrogen atom to eliminate the double bond between the two carbons.  

Explanation:

Unsaturated fat has one or more double bonds in its molecule. Saturated fat has a single bond. If you want an unsaturated fat to become saturated it needs to gain more more hydrogen atoms which will eliminate the double bonds between carbons of the unsaturated fat.

Hope this helped :)
