when a metal can replace another metal in a chemical reaction - it is a chemically active metal
yes some chemical reactions are harmful to us. as digestion of food, photosynthesis, decomposition of organic waste are some examples of the useful chemical reactions.
Reactivity with water, oxidation, flammability
Mechanical weathering is physical changes that break down and/or cracks the rock, such as ice wedging, temperature changes, root growth, or animal activity. Chemical weathering is a chemical change that changes the chemicals of the substance to make a new one. Examples of chemical weathering include oxidation, acid rain, hydration, and carbonation.
Cooking is for example a chemical change.
The mathematical is answer is pi divided 1.23472 which will then have the matter of 3893 and then u will be able to figure out what chemical property is from doing none of this
soem examples of chemical sedimantery rock are limestone, and gypsum.
Co2

Synthesis, decomposition, combustion, and oxidation are some examples of chemical changes (reactions) of matter.
Acid rain
Examples of physical activity include running, swimming, cycling, weightlifting, dancing, and playing sports like basketball or soccer.
Energy that is stored into something and released by a chemical reaction is known as chemical energy. Some examples of these are batteries, gasoline, coal, and food.
No. See related links for some examples of its activity.
food or gas
flour or dough into chapati .
Wood, coal, gas.
Examples: chemical reactivity, flammability, tendency to explode, etc.
