quentin06:What truth .....Mr man go & read what u wrote up there ,and judge urself,if u made an atom of senses in relationship to the discussion on ground ...and also, stop barking like a malnourished African dog ! It will go a long way in helping u in life ,my candid advice.Abi na woman self...... |

Wow !! We celebrate u dear..... |
Good morning nairalanders...... Pls,I will appreciate if someone can solve these empirical problems 4 me in chemistry.................. .....giving me tough time #- 20cm^3 of a gaseous hydrocarbon were mixed with 90cm^3 oxygen,& the mixture exploded. At room temperature,60cm^3 of gas were left.40cm^3 of the gas (carbon (iv) oxide ) were absorbed by sodium hydroxide,leaving 20cm^3 of oxygen.. Find the empirical formula of the hydrocarbon. #- 10cm^3 of a gaseous hydrocarbon were mixed with excess oxygen & ignited... The total gas volume was measured at room temperature & pressure before & after combustion,& it was found that it contracted by 20cm^3. On shaking,the remaining gases with excess potassium hydroxide solution,the gas contracted by a further 40cm^3. What's the molecular formula of the hydrocarbon. And lastly, #- 6.10g of boron reacted completely with 22.9g of chlorine to give 29.0g of the metallic chloride. Calculate the empirical formula of the chloride.. Thanks in anticipation.... Working & simplicity is the principle aspect,thanks... |
