Circular motion question under Physics

The circular motion of a particle in the x-y is given by the equations:

r(t)= 7.23m

Theta(t)= (6.33rad/s)t

Where r is the distance from the origin and Theta is the polar angle measure counterclockwise from the positive x-axis. Calculate the x-coordinate of the particle at time t=2.50s

General question question under main group

When a 0.998g sample of CuSO4.xH20 was heated strongly,so that the waters of hydration were given off,the mass of the anhydrous salt remaining was found to be 0.638 g.What is the experimental value of the percent water of hydration?

General question question under main group

Subject: Heat of mixingnnnHi Therenn[Sigurd Skogestad, page 113, question 4.7b].I ve tried this question at it is on the textbook,but i get a different answer,where am I going wrong? nn For the following assume the same initial temperatures before mixing.(20Â°C) a. Calculate the adiabatic temperature rise when we mix 0.5kg sulphuric acid with 1kg water. nYou are given the following information: nHeat of mixing = -96kJ/mol H2SO4nMolecular weight for the acid = 98.1g/mol Specific heat capacity of water= 4.18 kJ/kg K nnnnn Solutionsna. 500g =500/98.1 = 5.09 mol H2SO4 nn1kg = 1000/18 = 55.5 mol H2OnEnthalpy mix = -96*5.09 = -489.3 kJ/kg solution (used -96kJ/mol because mol of water >10) Temperature change = -489.3/4.18=117 K.nnTextbook answer is 72 K
