What is a substance that helps chemical reactions?
A substance that helps chemical reactions is called a catalyst. It speeds up the rate of a reaction by providing an alternative pathway with lower activation energy. Catalysts are not consumed in the reaction and can be used repeatedly.
Why are chemical reactions so important?
It keeps us warm when we burn firewood and it is the gas that we fuel our cars with.
Which part of an atom plays a major role in chemical reactions?
Chemical reactions are a result of valence electron transfer and/or sharing. Valence electrons are located in the outer-most orbitals of the reactant elements. In a sense, though, you could say protons are also involved in chemical reactions. Although an element will never donate, accept, or share protons in a CHEMICAL reaction, they are part of the determination in an elements reactivity. Reactions that do involve protons are termed "nuclear reactions," and are not chemical reactions. In fact, a lot of the methods used to determine chemical reactions -- such as enthalpy -- cannot even be applied to nuclear reactions. Neutrons, like protons are involved in nuclear reactions, but never in chemical reactions. Hope this helps!
Two types of chemical reactions?
Two kind of chemical reactions are exothermic and endothermic reactions. An exothermic reaction is one that releases energy. An endothermic reaction is one that absorbs energy. Hope this helps!! :)
Why do reactions go towards equilibrium?
Energy likes to stay in chemical bonds that are stable.That is the simple answer. Hope it helps
Which part of the cell membrane helps chemical reactions happen?
The Enzymesenzymes
What part of the membrane helps chemical reactoins happen?
Enzymes
What is the substance called that helps chemical reactions happen in the body?
enzymes carry out chemical reactions, and enzymes are in proteins, so preoteins carry out chemical reactions
What helps chemical reactions occur?
A catalyst helps chemical reactions occur.
What energy helps chemical reactions to form?
Heat helps chemical reactions to take place. Light can also cause some chemical reactions to take place.
Which part of an animal cell helps control all chemical reactions within the cell?
This is the cell membrane. It surrounds the outside of the cell.
How enzymes control chemical reactions?
enzymes helps control chemical reactions by the chemical in it called collagen when enzymes enter your body they create a chemical reactions and controls the chemical reactions you get by eating too much acids.
What is the significance of chemical reactions in daily life?
Chemical reactions helps life to go on,in that it helps the process of metabolism within cells of living things.
What part of the membrane helps chemical reaction?
ENZYMES!!
What is the of cytoplasm in a plant cell?
It helps maintain the cells shape
