ETEA 2022 Full Course Test October 27, 2022 by ilmkidunya [ad_1] Today we are going to Upload ETEA 2022 Full Course Test Don’t focus on how you’ll fail: focus on how you’ll win “Forget all the reasons it won’t work and believe the one reason that it will.” ― Unknown 10 / 200 10. Approximately 80% of the total RNA contents of a cell are? Explanation: There are three types of RNA found in the cell Transfer RNA : Does translation Messesnger RNA : Does transcription Ribosomoal RNA : Is found in the ribosome The most abundant of these three is the ribosomal RNA. Ribosomal RNA also has the largest size among RNA 29 / 200 29. An immersion heater of 400 watts kept on for 5 hours will consume electrical power of __________________? EXPLANATION: as from the given condition P=400watt t=5hours power in terms of KWh will be KWh=400×5 KWh= 2000(by moving decimal from right to left) =2×103 =2KWh 142 / 200 142. Which is the correct order of decreasing acidity of lewis acids? EXPLANATION: It is because of pi back bonding. All the halides having lone pairs donate one lone pair to boron by overlapping with the p orbital of boron. Due to large size of p orbital of halides the effective overlap between orbital’s decreases. So the electron deficiency of boron atom in its halides follow the trend–BI3>, BBr3,>BCl3>BF3. A species which is more electron deficient will pull electron easily and hence will be more acidic 154 / 200 154. If 1 ampere current flows through 2m long conductor the charge flow through it in 1 hour will be_______________? EXPLANATION: as we know that Q=It I=1A and t=1hour=3600seconds Q= 1A×3600seconds Q=3600C 165 / 200 165. The volume occupied by 22.4 g of a gas ( vap. density =11.2) at NTP is: Explanation: We know that, Molecular mass=2× vapour density =2×11.2 =22.4 gm At NTP, Number of moles =22.4/22.4=1 mole Volume occupied by 22.4 g gas =1×22.4 =22.4 L 189 / 200 189. The complex [CO(NH3)3 (NO2)3] is named as EXPLANATION: Option 1 is correct Option 2 is wrong because nutral ligand is named 1st than negative ligand which is wrong Option 3 is also wrong because nutral ligand is named 1st than negative In option 4 the Oxidation state of Cobalt is given II which is wrong. Your score is The average score is 5% [ad_2]
