A 10.0 gram sample of a compound that had a molar mass of 156 g/mol is placed into a perfect calorimeter containing 100.0 mL of water. It decomposes in aqueous solution and the temperature rises from 25C to 35C. For this compound, what is the enthrall of decomposition?

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying

elements make up everything, and they combine to make compounds.

the answer is c
