What else can I help you with?
When rocks undergo metamorphic changes chemical reactions cause minerals to recrystallize or change form which agent provides the energy for these reactions?
Heat
What chemical cause blood vessels to constrict?
Two examples are histamines and amphetamines.
Why does a change in body temperature indicate that a chemical reaction may have occurred?
A change in body temperature can indicate a chemical reaction because most chemical reactions involve the absorption or release of energy in the form of heat. If the reaction absorbs heat from the surroundings, it can cause a decrease in temperature, while if it releases heat, it can cause an increase in temperature. Monitoring changes in body temperature helps to detect and analyze chemical reactions.
What kind of physical hazards can some chemicals create?
it can cause a fire, explosion and dangerous chemical reactions
What would cause the greatest decrease in the rate of chemical reaction?
For most reactions, the lowering of the temperature of the reactants.
What are the 5 examples of chemical energy sources?
Fossil fuels such as coal, oil, and natural gas. Biomass from plants and organic materials. Hydrocarbons in gasoline and diesel fuel. Chemical reactions in batteries and fuel cells. Nuclear reactions in uranium and plutonium.
What energy helps chemical reactions to form?
Heat helps chemical reactions to take place. Light can also cause some chemical reactions to take place.
Can chemical reactions give off electrical energy?
Yes. Electricity can cause a chemical change. On the History channel they showed electricity doing something to a copper penny that made a chemical change .(don't exactly what the electricity did to it but it did cause a chemical change)
Why cant a chemical reaction be put back the same?
cause chemical reactions cant be reversed
What are the chemical reaction that cause pollution?
Chemical reactions that cause pollution include combustion of fossil fuels, which releases pollutants such as carbon dioxide, sulfur dioxide, and nitrogen oxides; production of chemicals like ammonia, chlorine, and pesticides that can contaminate soil and water; and reactions involving volatile organic compounds (VOCs) that form ground-level ozone and contribute to smog. Industrial processes, vehicle emissions, and agricultural activities are common sources of these polluting reactions.
When rocks undergo metamorphic changes chemical reactions cause minerals to recrystallize or change form which agent provides the energy for these reactions?
Heat
Why does vegetable oil smell like fish?
They chemical reactions cause a odour similar to that of fish.
What is chemical wearthering?
Chemical weathering is the breakdown of rocks and minerals through chemical reactions that cause changes in their composition. This process typically involves the interaction of minerals with water, oxygen, and other substances in the environment, leading to the formation of new minerals or compounds. Acid rain, oxidation, and hydrolysis are common examples of chemical weathering processes.
What is the effect of heat and cold?
Heat can cause expansion of materials, increase in molecular movement, and chemical reactions to occur more readily. Cold can cause contraction of materials, decrease in molecular movement, and slow down chemical reactions. Both heat and cold can impact the physical, chemical, and biological properties of substances.
