According to the law of conservation of charge which statement can be true? a) a metal rod lost charge. b) a silk cloth gained charge. c) charges are created from nothing. d) charge moved from hair to a balloon.

option (D)

Explanation:

According to the conservation of charge, the charge can neither be created nor be destroyed. It can transfer from one body to another body.

When we rub a balloon with the hair, due to friction, the electrons leaves the hair and then goes to the balloon. So, the hair becomes positively charged and balloon gets negatively charged.

This process is called the charging a body by friction or by rubbing.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
