Question

which statement best describes what happens when oil and water are stirred together? (1 point)
oil molecules repel each other, leading to complete mixing of the two substances
water molecules attract each other, but they will not attract oil molecules, causing separation
oil and water molecules have like charges, causing them to repel each other and separate
water are positively charged and oil molecules are negatively charged, causing them to repel each other and separate

Explanation:

Water is a polar molecule and water - water interactions are strong (hydrogen - bonding). Oil is non - polar. Polar water molecules do not interact favorably with non - polar oil molecules. This causes the two substances to separate. Oil molecules do not repel each other to cause complete mixing. Oil and water molecules do not have like or opposite charges in a way that causes separation due to charge interactions as described in the other options.

Answer:

Water molecules attract each other, but they will not attract oil molecules, causing separation
