Answer: pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.
Explanation:
look it up on the internet
Explanation:
When two substances chemically combine together then it results in the formation of a new compound whose chemical properties are different from the reactant species.
Thus, there will be change in the chemical composition when reactants combine together.
Therefore, we can conclude that if two substances combine to form a new substance with different properties, a chemical change has occurred.
Answer:
Bowling ball
Explanation:
They are traveling at the same speed, but the bowling ball has more mass. The bowling ball has more kinetic energy because more force is needed to stop the rolling bowling ball. Two balls with different masses moving at the same speed have different amounts of kinetic energy.
Answer:
So, look up for electronegativity table
There's a continuum for deciding whether the bond is non-polar, polar, or ionic
If electronegativity difference is less than 0.4 it's non-polar

Gas is the most compressible because the atoms have more space in between. solids on the other hand, are the least compressible because their atoms are really closely packed.
