What element speeds up chemical reactions?
1) Something that speeds up a chemical reaction but that is not changed by the reactions is called a catalyst.2)An element is a pure substance (not a compound) and while some elements (such as platinum) can speed up chemical reactions (eg platinum in a car exhaust catalytic converter), by far the most common catalysts are in fact compounds not elements. These compounds are organic in nature and called enzymes.
In what way are chemicals a part of your everyday lives?
Reactions are important; from our daily life to nature and scientific purposes, reactions are constantly done. For example, they do help us to cook the food, many reactions takes place in our body for instance the Respiration which is done by the burning of food and oxygen together which produces energy, water, etc. In the case of nature, it is used in the process of photosynthesis. Rusting is also caused br certain types of reaction. In the case of laboratory purposes, it is used for experiments. Thank you for referring to my answer; Rahatara
What is the meaning of 'chemical nature'?
It's ability to react in chemical meaning. Gold and silver don't react naturally so the don't got 'chemical nature'. But this which react got 'chemical nature'
Describe the factors which affect chemical reaction rates?
The factors that change the reaction rates of chemical reactions are: 1)temperature 2)concentration 3)pressure 4)physical state 5)a catalyst
How does the chemical nature of a phospholipid affect its solubility?
by adding the rate
Which are more in nature reversible or irreversible chemical reactions?
irreversible
On what conditions does a spontaneous reaction become spontaneous?
For some non-spontaneous reactions, you can change the temperature. For other non-spontaneous reactions, there is nothing you can do to make it spontaneous. Nature favors reactions that increase a system's entropy (disorder) and nature favors reactions that are exothermic (they release enthalpy). Any reaction that does both of these things is spontaneous at all temperatures. Any reaction that does neither of these things is never spontaneous. As far as this question is concerned, the interesting reactions are endothermic reactions that increase entropy and exothermic reactions that decrease entropy. Whether these reactions are spontaneous depends on the temperature. The first variety (endothermic, increase entropy) will be spontaneous at high temperatures; the second (exothermic, decrease entropy) will be spontaneous at low temperatures. To find the temperature at which a reaction becomes spontaneous, one may apply the Gibbs equation: DG = DH - TDS where capital Ds stand for the Greek capital delta.
Can you stop a chemical reaction from happening?
no... chemical reactions happen in nature however you can stop the two objects from combining
How are usually found?
In the nature the majority of chemical elements are found as compounds.
What are the special properties of enzymes?
Enzymes reduce the activation energy of a reaction. They accomplish this feat by altering the local chemical environment of the substrates while typically bringing the reactants into close proximity and even stabilizing conformers that promote reaction.
What does the study of chemical reactions have to do with classification and prediction?
we must classify its human nature to organize. and also to predict
Why can a chemical physical change not be reversed?
1. The chemical nature of the chemicals was modified; but reversible chemical reactions exist.2 . During a physical change the molecular structure of chemicals is not changed.
What is meant by the term chemical change Give 2 examples?
A chemical change is a change that imply the change of the nature of molecules. Examples: neutralization of an acidic solution, thermal decomposition and generally all chemical reactions.
Why did nature choose the specific 20 amino acids?
It is my belief that at that time when chemical reactions began nature chose the specific 20 amino acids because of the composition of the atmosphere of the early earth.
Are Spontaneous declarations of an incriminating nature made by suspects to officers following arrest admissible at trial?
Yes, spontaneous declarations of an incriminating nature made by suspects to officers following arrest admissible at trial.
