Yes, it is correct.
it is false as acid-base mixtures are neutral.
True. Water has a lower melting point than most rocks, so when a rock is wet, the presence of water can lower the overall melting point of the rock.
True. Venezuela is farther from the equator than Iran.
True. A wet rock generally melts at a lower temperature than a dry rock because the presence of water in the rock lowers its melting point due to the water acting as a flux, reducing the energy required for melting.
This is an acidic rain.
True. Substances with a pH less than 7 are considered acidic.
it is false as acid-base mixtures are neutral.
true
True. Water has a lower melting point than most rocks, so when a rock is wet, the presence of water can lower the overall melting point of the rock.
A pH lower than 7 indicates that the sample is acidic.
False. An acid-base mixture may be more, less, or equally acidic compared to the starting solutions depending on the specific pH of the components and their concentrations. The final acidity of the mixture is determined by factors such as their strengths, amounts, and their chemical interactions.
Any pH lower than 7 is considered to be acidic.
True
true. there are 656 muscles in the human body!
It's becoming acidic. pH of 7 is neutral, lower than that it's acidic
When the pH is lower than 7, the solution is acidic.
