A type of chemical reaction in which two or more reactants react to form a single product is known as COMBINATION REACTION ie, {a + b = c}. It is divided into three :- 1) Element + Element ----> Compound. (Eg :- 2H2 (g) + O2 (g) ----> 2 H2O (l).) 2) Element + Compound ----> Compound. (Eg :- 2SO2 + O2 ----> 2SO3.) 3) Compound + Compound ----> Compound. (Eg :- NH3 + HCl ----> NH4Cl.)

Answer: Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism. Enzymes and its examples:- 1) Amylase - Helps change starches into sugars. 2) Maltase - Also found in saliva breaks the sugar maltose into glucose. 3) Trypsin - Found in the small intestine, breaks proteins down into amino acids.

It acts like a safety device in domestic electric circuits which protect appliances from short circuits. It is usually made of materials with low melting points like copper or an alloy of tin and lead. So, whenever excess current flows through the circuit, the heat produced in the conductor would become high. This heat makes the fuse wire, connected in series with the circuit, melts off thus, disconnecting the circuit.

Fuse acts like a melting wire in electric appliance . It is connected to the wire so that if short circuit takes place, fuse will melt and break the circuit to prevent appliances catching fire

The force exerted by a magnet on another magnet or on a magnetic substance like iron, cobalt and nickel is called MAGNETIC FORCE. The rule is Fleming's left hand rule. According to this rule, on keeping our left thumb, forefinger and middle finger in mutually perpendicular directions, if the forefinger points in the direction of magnetic field and middle finger points in direction of current, then the thumb would point in the direction of force.

Chemistry is interesting and creative: Our world is made out of atoms, molecules and ions. Their behavior determines the properties of the substances we encounter in our daily lives: their structure, color, smell, and the way they interact with each other. Chemists use this knowledge in a creative way.
