Chemistry Questions

The main purpose of balancing chemical equations is to make the mass of reactants is equal to mass of products obtained after the reaction. Hence, to make law of conservation of mass is purpose of balancing chemica equations.

The simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons.

Here all the given options are hydrocarbons.

Atoms are composed of Electrons, protons and Neutrons. Protons and Neutrons together called as Nuclei.

The minimum amount of energy required for a particular reactants to convert into products and is called as Activation Energy.

This activation complex is also termed as Transition State because according to Transition State Theory at transition state the existing bonds tend to increase in length and become weaken while, the new forming bonds tend to decrease in length and start becoming stronger.

Hence, the activated complex is in transition between reactants and products.

Alcohol is a drug.

bullet proof material is made up of polymer Poly carbonates.

The acid used in lead storage cells is Sulphuric acid. They are used car batteries. Lead-acid batteries are capable of being recharged, which is important for their use in cars.
