The enthalpy change for an exothermic reaction is negative because heat is being released, so that takes out two of the responses. Since energy is being released into the surroundings due to the exothermic reaction, the potential energy of the products is lower than that of the reactants. Energy is being put in to make the reaction occur, but then that energy is all being released into the surroundings thus a lower potential energy level for the products
Density= mass/ volume
So density = 99/10= 9.9g/cm^3
Hope this helps!! xx
Answer:
A pH=3 is 1000 times as acidic as a pH=6.
i would try to figure out how to get off of my bed without getting hurt, then look for food which since i'm microscopic i can eat living organisms .Then try to figure out how to get places without getting stepped on . i would be very careful because diseases are microscopic and once i tough them i would die .but i would try to get outside and see what it looks like without getten eaten by another microscopic thing.
Is that enough dm me on instagram if you need more @ h20boii
