The mixture of carbon monoxide and hydrogen produced by a synthetic gas is known as water gas. This is from the water gas shift reaction, which was created by a physicist from Italy. Water gas is made by blowing steam through white-hot coke.

At 773 Kelvin in the presence of ferric oxide and chromium oxide, the water gas (carbon monoxide and hydrogen) along with steam is transformed into carbon dioxide and hydrogen. This is also known as bosch process.

When zinc is reacted with sodium hydroxide in the presence of heat Sodium zincate and hydrogen are formed the chemical formula of sodium zincate is Na₂ZnO₂. Therefore Sodium Zincate is made of sodium, zinc, and oxygen.

This type of motion can be called circular motion with increasing radius. As the radius increases, the tangential velocity increases (v = rw). Now, as there is only one velocity present, the speed will be equal to the magnitude of the tangential velocity.

The instantaneous velocity will increase with time. If the motion is accelerated, no matter if the acceleration is constant, or variable, the instantaneous velocity will increase. Variation of acceleration describes how to change in velocity is changing.

The function for velocity can be derived by differentiating the equation with respect to t. v = 2(t-4) is the required function. When t = 5, v = 2(5-4) = 2.

Frogs can live both on land and in freshwater and belong to class Amphibia of phylum Chordata. The most common species of frog found in India is Rana tigrina.

The body of a frog is divisible into 2 parts which are head and trunk. A neck and a tail are absent. Above the mouth, a pair of nostrils is present.

Eyes of frog are bulged out and are covered by a nictitating membrane that protects them while in water. On either side of the eyes, a membranous tympanum receives sound signals.

Food is captured by the bilobed tongue of the frog. Digestion of food takes place by the action of HCl and gastric juices secreted from the walls of the stomach.
