If the mass of metal sample are 10.138 g in initial temperature 49°c , and the mass for water in calorimeter 18.537g , in temperature of water in calorimeter 28°c . and the final temperature of water and metal is 31°c
calculate the changes in temperature of water and of the metal?

Achemical reaction (also known as a chemical change) produces substances that are chemically different from the starting materials. an example of a chemical reaction is the formation of water from hydrogen and oxygen gas.in a physical change, a substance changes its physical appearance but not its chemical identity. an example of physical change is the formation of liquid water from solid water, a familiar process called melting. physically, liquid water looks very different from solid water (ice) but the chemical identity, water, is the same for both. which of following changes that affect the composition of our atmosphere involve physical changes and which involve chemical reactions? oxygen gas changes to ozone during thunderstorms carbon dioxide is produced by the combustion of gasoline in an automobile engine. when coal, oil, and natural gas are decomposed in landsills they produce methane gas. freezing rain develops when a warm air mass overrides a cold air mass. fog forms from water vapor when the temperature drops below the dew point

Idon’t know how to solve this question

If a reactant was removed, did the new equilibrium system shift to make more reactants or more products?
