A 5.00-g sample of one of the substances listed in Table 6.1 was heated from 25.2C to 55.1C, requiring 133 J to do so. What substance was it? With this knowledge, It takes 585 J of energy to raise the temperature of 125.6 g mercury from 20.0C to 53.5C. Calculate the specific heat capacity and the molar heat capacity of mercury.

Develop forecasts for the PET-PX margin based on contract pricing using data from (a) Jan. 2000-Oct. 2010, (b) Jan. 2006-Oct. 2010, and (c) Oct. 2009-Oct. 2010. In each case, predict the PET-PX margin in Jan. 2020. Which forecast appears to be mos..
Assuming that there are no other significant side reactions, calculate masses of alcohol and ether produced, per 1000 kg of allyl chloride fed to the reactor.
In Uniformly varying load in simply supported beam, when we are calculating reaction at support we say centorid of triangle will be at 2x/3 from a to b. but, when calculating moment we say centroid will lies at x/3 from a to b, why?
