Why +ve P.F. gives nuclear instability where as -ve PF gives nuclear stability? Explain
Calculate the vapor pressure of water above a solution prepared by adding 23.5 g of lactose (C12H22O11)to 200.0g of water at 338K . (Vapor-pressure of water at 338K 187.5 torr.)
How does an increase in pressure effect the solubility of a gas in a liquid. A. As pressure increases, gas solubility increases. B. As pressure increases, gas solubility remains the same.
Excess Ag2CO3 is added to an 0.2 M K2CO3solution. Calculate the equilibrium concentration of Ag+ under these conditions.Ksp for Ag2CO3 is 8.1 x 10-12.
The atomic weight of Sm is 150.36 and that of Nd is 144.24. The isotopic percentage abundance of 147Sm is 15.0 and that of 144Nd is 23.954.
Examination of the product mixture revealed that only about half of the starting material had been consumed and practically no PhCOCHBrCH3 was present. Explain these observations and draw the product that did form in the reaction.
What mass of calcium can be produced by this process if a current of 5900 A is applied for 55 h? Assume that the electrolytic cell is 60 % efficient.
A typical automobile gets 30 miles per gallon of gas and drives 12,000 miles every year. Assuming that octane (C8H18, density 0.7025 g cm-3) is a principal component of gasoline
What is the voltage of a voltaic cell composed of Li(s) l Li+ (aq) ll Cu+2 (aq) l Cu(s) at 298 K under standard state conditions. What is ?G° for this reaction
How much would the beaker and its content weigh if it was completely filled with mercury? The density of mercury is d = 13.5 g/mL ? = g
Why is high pressure needed in Hplc? And what is a bonded phase in liquid chromatography
Question- We considered mixing a strong base with a weak acid, but we did not consider mixing a strong acid with a weak acid. Consider mixing 0.1M HNO3and 0.1M HNO2. Predict the pH of the solution and the percent ionization of the nitrous acid. Ra..
Question- The hydrogen atom is not actually electronegative enough to form bonds to xenon. Were the xenon-hydrogen bond to exist, what would be the structure of XeH4? Double-click any atom and type Xe to change the label. Draw the molecule by plac..
