7. Some students heat a silver bar with a Blowtorch until it reaches a temperature of 250.6 °C. (Just as a random fun fact, the melting point of Silver is 961.8 °C). The silver bar has a mass of 300.05 grams. If they add the gold
bar to 342.6 grams of water in a calorimeter), and the temperature of the water/metal combo rises to 63.5 °C.
How many Joules of Heat Energy did the silver bar release as it cooled? Assuming that the water absorbed that
same amount of Energy, what must the initial temperature of the water been? Use the Specific Heat Capacities
in the Table below to solve.

What’s the question

Sorry i dont understand the question can you rephase it?

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f.
