The D H of a reaction depends upon the physical states of reactants and products. For example, when hydrogen and oxygen gases combine to give liquid water, the heat of reaction is different than when they combine to form gaseous wate..

The product of the slopes of two perpendicular lines is ___. => 0 or 1 or -1 or Not defined..

Haploids are organisms, whose cells contain haploid number of chromosomes - as against normal diploid number of chromosomes. Haploid cells are usually found in gametes of any organism. But when entire plant body contains haploid cells - it offers a great advantage as such plants are comparable to ..

The product of the slopes of two perpendicular lines is ___. => - 1 or 1 or 0 or Not defined..

The table gives information about the sugarcane production (in millions of tons) in five major states over the years. How many states produced more than 20% of the total sugarcane production in the year 1992? => 2 or 3 or 1 or 5..

Transition State Theory - According to this theory, the reactant molecules must come together to form an arrangement of atoms/molecules that facilitates the formation of products. This arrangement of the reacting species is called the transition state. A simple way of ..

Sulphur Production and Allotropes - Sulphur is the second member of the oxygen family, yet it differs from oxygen in many respects. For e.g., O 2 exists as molecule while S 2 molecule does not. The difference in the chemical behavior of S and O arises due to following reasons. (i) Oxygen ..

Ordered Pairs and Cartesian Product - In a Rectangular Cartesian System of coordinates the position of a point in a plane is determined by an ordered pair whose elements give the distances from the intersecting straight lines at right angles to each other. These lines ..

Introduction - One of the primary objectives of agriculture is to produce food. In the entire history of agriculture, food production has remained a prime objective. Human food needs have undergone many qualitative and quantitative modifications in the last 50 - 100 years. Mainly, the qua..

The line graph shows the variation in price of a product. Between which two years was there a maximum increase in the price of the product? => 1995 and 2000 or 1980 and 1985 or 1975 and 1980 or 1990 and 1995..
