Since the force required to lift it is equal to its weight, it follows that the gravitational potential energy is equal to its weight times the height to which it is lifted. PE = kg x 9.8 m/s2x m = joules.PE = lbs x ft = ft lb. What is the formula to calculate potential energy?
with quantum chemical calculation, I would like to ask you how to calculate the potential energy ...

Example 1: Calculate the temperature change that results from adding 250 J of thermal energy to 0.50 moles of mercury. Visualize the diagram of the Heat System and Surroundings with the arrow direction going into the system. Use the formula: _q = nCmΔT_ Since you are asked for the change...
How to Calculate the Stoichiometric Ratio. Stoichiometry is a type of math associated with chemistry. In stoichiometry, you perform calculations pertaining to moles (the basic unit of weight in chemistry), masses and percentages. A stoichiometric ratio s

To calculate the amount of heat released in a chemical reaction, use the equation **_Q = mc ΔT_**, where **_Q_** is the heat energy transferred (in joules), **_m_** is the mass of the liquid being heated (in kilograms), **_c_** is the specific heat capacity of the liqu...
Take the negative log base 10 of the result from the previous step to finally calculate the alkalinity, or pOH, of the unknown solution. Example: Alkalinity of unknown solution = pOH = -log [OH-] = -log 0.004 = 2.4 Step 8 Convert to the more familiar term of pH by subtracting the ...
So, you'll want to plug the absorbance value for each unknown into the equation in place of y, then calculate x. You can use the spreadsheet program to do this calculation for you and make it quicker. You have now calculated the concentration of the chemical of interest in three of your...
