the standard solution of sodium carbonate into a conical flask. Add two or three drops of methyl orange indicator and titre this solution with KA1. Readings are recorded in the table. The titration is repeated three times to achieve accurate results. Results: Titration number | Rough | Accurate | | | 1 | 2 | 3 | Final reading/cm3 | | | | | Initial reading/cm3 | | | | | Volume of KA1/cm3 | | | | | Mass of beaker + sodium carbonate= _________________ Mass of empty beaker

conducted on attactiveness scores of chosen mate. Mauchly’s test indicated that the assumption of sphericity had been assumed for the main effect of alcohol amount‚ χ²(5) = 4.70‚ p > .05 and alcohol amount and lighting type interaction effect‚ χ²(5) = 2.58‚ p > .05. There was a significant main effect of type of lighting on attractiveness of chosen mate‚ F (1‚ 25) = 23.42‚ p <.001‚ partial η² = .48 (See table 1). Results showed that attractiveness score of the chosen mate was significantly

Ionic Reactions Results B - Do your results agree with your expectations from the solubility rules/table? Our results seemed to largely agree with the established solubility rules/table; however‚ a few reactions with the commonality of being mixed with Co(NO3)2 (cobalt nitrate) [reference Row A‚ Columns 2‚ 3‚ and 4] seemed to have such a pale pink tone that it was difficult to decide whether that could have been a precipitate or the lighting in the area where the experiment took place.

deterioration in macroeconomic indicators and a marked deceleration in the investment momentum aggravated bearish sentiments in the capital markets. Infrastructure sectors have been hampered by resource constraints and other issues. Investment decisions‚ as a result‚ have seen prolonged deferment‚ with only a few projects being awarded. It is heartening‚ however‚ that the intrinsic strengths and embedded characteristics of the Indian economy still remain positive. GDP growth‚ at 6.5%‚ though sharply down from
