Answer:the initial composition of the reactants is
40cm^3 of CH4
40cm^3of H2
100cm^3 of H2O
Explanation:
Balanced reaction is
CH4 +H2+5/2O2______
CO2 +3H2O
Excess KOH at room temperature absorbs CO2 whose volume is given by 40cm^3 i.e the volume by which the solution decreases
So using Gay lussac combining ratio which states that gases combine in volumes that are in simple ratio to each other if gases.
Since CO2 in the equation is 1 mole
Means 1mole represent 40cm^3
So CH4:H2:O2 are in ratio of 1:1:5/2=(40:40:100)cm^3 respectively.
A lever is a machine made of fulcrum and rigid beam. Force is added to either side of them beam.
To understand what makes a material hard, it is necessary to look at the atomic structure of its crystals. ... In diamonds, however, the carbon atoms are bound together in a tetrahedral formation, a shape that is extremely rigid. Combined with the strong carbon to carbon bonds, it makes diamond extremely hard
Hope this helps
