hi i needed solutions in the following questions. please also show the steps of solving them.
Q1.A mixture of 10cm3 of methane and 10cm3 of ethane was sparked with an excess of oxygen. After cooling to room temp, the residual gas was passed through aqueous potassium hydroxide. what vol. of gas was absorbed my the alkali?
Q2. An aqueous solution contains 1 mol of S2O3 ions and this reduces 4 mol Cl2 molecules. What is the sulphur-containing product of reaction?
Q3.when 20cm3 of gaseous hydrocarbon were completely burnt in an excess of oxygen, 60cm3 of CO2 and 40cm3 of water vapour were formed. what is the formula of hydrocarbon?
Q4. A mixture of 10cm3 of oxygen and 50cm3 of hydrogen is sparked. what is the maximum theoretical decrease in volume.(all gas volume are at 298K)
Q5. how many atoms of carbon are present in 18g of glucose.
Q6. A 0.20g sample of monobasic acid requires 8.0 cm3 of 0.40 mom dm-3 sodium hydroxide for complete reaction. what is relative molecular mass of the acid?
