Some signs (or evidence) of chemical change are: a gas is produced, the temperature changes, a substance disappears, a solid is formed a colour change occurs, a new odour is produced.
Chemical weathering is most effective in warm and wet climates where water and heat can drive chemical reactions that break down rocks. These conditions provide the necessary ingredients and energy for chemical reactions to occur and break down minerals in rocks over time.
Chemical weathering occurs when rock is broken down and dissolved through chemical reactions. It can happen anywhere, but is more common in areas with high moisture and temperature fluctuations, such as tropical regions and near coastlines.
A warm and humid climate is most prone to chemical weathering. High temperatures and moisture promote chemical reactions that break down rocks and minerals over time.
Chemical weathering is most effective in warm humid climates, where high temperatures and abundant moisture can accelerate the chemical reactions that break down rocks. In cold dry climates, the lack of moisture limits the availability of water for these reactions, making chemical weathering less impactful.
Those 2 months probably have the highest rates of chemical weathering because environmental conditions like temperature, humidity, and rainfall are most conducive to chemical reactions that break down rock and minerals during that time. Increased moisture can enhance chemical reactions, and warmer temperatures can accelerate the chemical weathering processes.
These are decomposition reactions.
Oxygen as most reactions have it although it could also be hydrogen
Wind, water and chemical reactions.
is the colour change, tempeture change ,gas produced the most common ones
Most chemical reactions occur in water, which is an inorganic compound. Water's unique properties, such as its ability to dissolve many substances, make it an ideal medium for chemical reactions to take place.
It speeds up the chemical reactions so most reactions wouldn't happen without water.
There can be many, kinetic (explosion), radiation (light) but the most common and the one people think of is thermal.
ATP is a most common substance that participate in chemical reactions of a living cell. They supply the energy needed for the reaction. They are made of adenosine base,3 phosphate groups and a nitrogenous base.
air
Most chemical reactions within cells could not take place without water
The primary factor that determines which substance is most responsible for chemical reactions is the reactivity of the substances involved.
The most common way to speed up chemical reactions in non-living systems is to add heat. Heat causes the molecules to move faster, creating more collisions. In some reactions, extra oxygen is used to speed them up.
