Why benzene undergo electrophilic substitution reaction easily and nucleophilic substution reaction with difficulty easily and?
the electron in benzene are delocalised making d ring to be elctron rich,thereby undergoing electrophilic substitution.benzene cannot undergo nucleophillic substitution,it can only undergo if it is substituted with an electron withdrawing group
What is a ''non'' reversible reaction?
A reaction which cannot be reversed is called an Irreversible reaction.
Do yeast have chloroplast?
No.Yeast are type of fungi.No fungi is photosynthetic
What is the law of the conversation of matter?
energy that can not be created or destroyedthe total number of atoms cannot change during a reaction.
Is a catalyst used up in a reaction?
Yes, a catalyst can be re-used, because It is NOT actually used in a chemical reaction. A catalyst will increase the rate of reaction by attracting reactants, but the catalyst is not a reactant. However, the reuse cannot be done indefinitely then, depending on the severity of the reaction conditions, it can be occur a small, but accumulative deactivation of the catalys.

Do only animals undergo mitosis?
noEvery organism with a nucleus can undergo mitosis. Prokariyotes cannot undergo mitosis
Can an element undergo a decomposition reaction?
yes.example:H2O ---> H2 + Othis can be done by electrolysis if you want to decompose water into hydrogen and oxygen.ANS2:An element, that is to say, an uncombined atom, cannot chemically decompose further but, elements that were combined initially can participate in a decomposition reaction. The example given in the first answer describes the decomposition of a compound, water.
Why ammonia cannot be dried up using concentrated sulfuric acid?
Ammonia is basic and Sulphuric acid is acidic. hence it undergo acid base reaction forming salt and water
Lost neurons cannot be replaced because mature neurons cannot?
undergo mitosis.
Do sponges undergo meiosis?
Sponges undergo mitosis, not meiosis. Sponges are asexual, so they cannot exchange DNA between each other and must undergo mitosis to reproduce.
What is a ''non'' reversible reaction?
A reaction which cannot be reversed is called an Irreversible reaction.
Which reaction cannot proceed without an activation energy?
An exergonic reaction
Who cannot undergo venography?
Venography usually is not performed in patients with kidney (renal) problems.
When do muscles undergo fermentation when?
During hypoxic conditions when they cannot get enough oxygen.
Do yeast have chloroplast?
No.Yeast are type of fungi.No fungi is photosynthetic
What is the law of the conversation of matter?
energy that can not be created or destroyedthe total number of atoms cannot change during a reaction.
