If you have 0.752 L of C2H60, and it has a density of 0.789 g/cm3, how many moles of ethanol do you have? [Select] III. What are the oxidation numbers for each atom in C2H60? C - [Select] 4:H - (Select) [Select) IV. Is CzH.O an ionic compound, a covalent compound or an acid? [Select VI. Looking at the number of moles of C2H60 you calculated in the first question, how many total moles of gas will be produced? [Select)

Answer 1

Given reaction is GH Goes + O2 (g) CO2(g) + H₂O(g) SHE-13070.7 volume of Ca HGO =>52 L- ης28/ ML = 752 cm3 (1m (m) Denning of Calgo = 0.789 g/cm² wt of C2H60 = 752 X 0.789 593.3289 Number moles Given mars न Molar mans of CatGo = 2x12 +6+1+ 16 = 46 593.328 : Number of moles of C2H60 46 = 2.898 3 stoneline of C₂ M60 il C H5OH is H H -&-o-H H H Now in case of covalent bond oxidation number represents hypothetical charge In Cansoh ,o is more election than CEH io negative & atract shared election pairs tourand itself.
