How is the increase or decrease of temperature a chemical change?
An increase or decrease in temperature can lead to a chemical change by affecting the rate of chemical reactions. Higher temperatures can speed up chemical reactions by providing more energy for collisions between reactant molecules, leading to new substances being formed. Conversely, lower temperatures can slow down or even prevent certain reactions from occurring due to the decrease in kinetic energy available for the reaction to take place.
Why is endo favored over exo in certain chemical reactions or processes?
Endothermic reactions are favored over exothermic reactions in certain chemical processes because they absorb heat from the surroundings, which can help maintain a stable temperature and prevent overheating. This can be beneficial in reactions that require precise control of temperature or in processes where excess heat could be harmful.
Is it true that lowering the temperature slows down most chemical reactions?
most chemical reactions dealing with enzymes preform best in a certain small temperature range, so increased or decreased temperatures could result in the slowing down of reactions
What is a chemical change and a chemical reaction?
There are certain types of chemical reactions describing what happens to certain reactants, such as combustion, single replacement, double replacement, etc. All of these processes change one kind of reactants (original substances) into different products (new substances) with a new combination of atoms arranged in a way to have completely different properties.Chemical reactionsare chemical changes. Reactions are just more specific.
According to modern chemistry what causes chemical reactions?
Chemical reactions are caused by the rearrangement of atoms in molecules to form new substances. This rearrangement occurs when chemical bonds are broken and new bonds are formed between atoms, resulting in the transformation of reactants into products. Factors such as temperature, concentration, and the presence of catalysts can influence the rate and outcome of chemical reactions.
When a person gets hypothermia the enzymes in their body become less active how does this change affect the body's chemical reaction?
most chemical reactions require a certain input of energy, meaning they need to be at a certain temperature. when the temperature is too low or too high, these chemical reactions cant take place.
What are the key principles of equivalence chemistry and how do they apply to chemical reactions?
The key principles of equivalence in chemistry refer to the concept that substances can react in specific ratios to form products. This principle is crucial in understanding chemical reactions as it helps determine the amount of reactants needed to produce a certain amount of products. In chemical reactions, the principle of equivalence ensures that the reactants and products are balanced in terms of their quantities, allowing for accurate predictions and calculations in chemical reactions.
What According to modern chemistry what causes chemical reactions?
A chemical reaction is caused by two compounds colliding. This happen with certain amount of force.
What substances react with bleach?
Common substances that can react with bleach include ammonia, vinegar, and certain acids. These reactions can produce toxic gases such as chloramine or chlorine gas, which can be harmful if inhaled. It's important to avoid mixing bleach with other household cleaners to prevent dangerous chemical reactions.
Proteins that speed up certain chemical reactions?
an enzyme
Are chemical reactions always spontaneous when H is negative and S is negative?
No, when H and S are both negative, the reaction will only be spontaneous below a certain temperature
Do chemical reactions need gravity?
No, chemical reactions do not require gravity to occur. Chemical reactions involve the rearrangement of atoms and molecules, which can happen in the absence of gravity. Gravity may influence the rate or behavior of certain reactions on Earth, but it is not necessary for the reactions themselves.
