Use the discriminant of the given function to predict how many solutions it has. Also check if the solutions are real or imaginary. 9 x 2 + 17 x - 9 = 0 => 2 imagin..

The compound has -COOH group as the functional group. Therefore, the main chain should be with this group in it, and -COOH group should be numbered as 1. The numbered C-chain then is, Thus, the compound should be named after propane (a 3-carbon alkane). The presence of -COOH group thus..

The energy of a photon is given by E = h n where the frequency of light = 3.0 x 10 1 5 s - 1 Planck's constant, h = 6.63 x 10 - 3 4 J s E = (6.63 x 10 - 3 4 J s) x (3.0 x 10 1 5 s - 1 ) = 6.63 x 3 x 10 1 9 J = 1..

The problem is done in steps: Calculation of the percentage of chlorine: We know that, Cl = AgCl 35.5g (108 +35.5)= 143.5? 5 mg Then, Percentage of chlorine in the sample = Empirical formula = C 3 H 2 Cl Empirical formula mass = (3 x 12 amu + 1 amu + ..

Since the tangent to the given curve is parallel to the line 4x - 2y + 5 = 0 Slope of the tangent = Slope of the given line ..

The volume of H 2 SO 4 neutralised by N/10 NaOH can be obtained as follows: N a c i d x V a c i d = N a l k a l i x V a l k a l i Therefore, Volume of N/5 H 2 SO 4 used for neutralizing NH 3 = (100 - 77) mL = 23 mL Then, Percentag..
