24 g of carbon reacts with some oxygen to make 88grams of carbon dioxide . Find out how much oxygen must have been used ,

64g of an organic compound contains 24 g of carbon, 8gm of hydrogen and the rest oxygen. The empirical formula of the compound is

complete the paragraph by choosing the appropriate words given in the brackets : (external, inhalation, alveolar, breathing, resptration, exhalation) Release of energy from the assimilated food is called .......... Inhalation and exhalation is called ................. When.............. is done, air enters the lungs. The oxygen from this air enters the blood while carbon dioxide from the blood exits from the blood, Through .................. CO_2 is given out. This gaseous exchange occurs through ......... membrane. This is called................ respiration. The RBCs carry oxygen to every cell.

Find the odd one out: Carbon dioxide, oxygen, sulphur dioxide, nitrogen dioxide.

A welding fuel gas contains carbon and hydrogen only. Burning a small sample of it in oxygen gives 3.38 g carbon dioxide, 0.690g of water and no other products. A volume of 10.0L (measured at STP) of this welding gas is found to weigh 11.6 g. Calculate empiracle formula
