Which of the following statements about energy in systems is true? when energy is transferred or transformed within a system, some matter must be changed into energy so that the total amount of energy remains constant. the total amount of energy in a system must be equal to the total amount of matter in that system. energy can be transferred or transformed inside or outside of a system, but energy cannot be destroyed?

1= 26.17

2= 1.17

3=30.86

4=5.86

just took the assigment on edge

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!
