First, calculate the number of moles. Moles = grams/molecular mass = 180g 180 g mol → grams cancel out = 1 mol There are 12 hydrogen atoms in glucose, and to find the number of atoms you need to …

To calculate standard cell potential, you use the formula: E_ (cell)^@=E_ (red)^@+E_ (o x)^@, where E_ (cell)^@ is the cell potential, E_ (red)^@ is the reduction potential and E_ (o x)^@ is the oxidation …

The integral is convergent and converges to 1 To calculate this improper integral, first calculate I=int_1^a (lnxdx)/x^2 Perform this integral by parts u'=1/x^2, =>, u=-1/x v=lnx, =>, v'=1/x intu'v=uv …

DeltaH=+2034 kJ mol^-1 or DeltaH=+726 kJ mol^-1 If the reaction in question is exactly as you have written the answer should be +2034 kj per mol. But when hydrogenating ethene generally the …

May 1, 2017 · Explanation: The formula to calculate the heat change of a reaction is ΔH = -mcΔT (where m is the mass of the fluid whose temperature changes which in this case is water, c is the specific …

Use a calculator: cos^-1(-.94)=160.052^@ Make sure that you are in the correct units for the question. My calculator was set in degrees, but your instructor may ask that you answer in radians. The …

Step 3) Substitute #1# for #y# in the solution to the first equation at the end of Step 1 and calculate #x#: #x = 3 - y# becomes:

To solve a problem like this, first determine the limiting reagent, then calculate the number of moles of product, and finally convert to grams of product. 1) Write the balanced reaction so you'll know the …
