By quantitative experiments he proved that when chalk is burnt it is changed into
lime and carbon dioxide ; and that when burnt lime is exposed to air , it slowly
combines with carbon dioxide and chalk is re - formed . 51 Lavoisier carried on

Accurate analyses of air have shewn that 100 parts by weight of dry air freed from
carbon dioxide ( v . infra , par . 113 ) are composed of 23 parts of oxygen and 77
parts of nitrogen , by weight . The simplest formula which will fairly accurately ...

But besides these gases , air contains small quantities of the compound gases ,
carbon dioxide , ammonia , and watervapour . The composition of air varies
within narrow limits . Thus air has not that fixity of composition which as we have

The air to be analysed is freed from carbon dioxide and ammonia , and is then
passed into the tube , and the volume is measured by reading off the level of the
mercury . A quantity of hydrogen equal in volume to nearly of the volume of air is
