The production of water proceeds according to the following equation. 2H2(g) + O2(g) → 2H2O(g). Which describes a way to speed up the collisions between hydrogen and oxygen molecules to produce more water?
Answer: Out of all the options shown above the one that best describes a way to speed up the collisions between hydrogen and oxygen molecules to produce water is answer choice C) Place the reactants in a smaller container.
I hope it helps, Regards.
A. is right because the waves are at the top and as u get deper of course the energy will decrease
Well since covalent bonds are strong and diamonds contains a lot of covalent bonds, it makes the diamond's melting point and boiling point very high.
Now to solve this problem, we are given the number of atoms
therefore we must first convert this into number of moles. We can do this by
using the Avogadro’s number. Calculating for number of moles of Carbon:
number of moles Carbon = 21 atoms of carbon (1 mole / 6.022
x 10^23 atoms C)
number of moles Carbon = 3.49 x 10^-23 mol C
Converting this to mass by multiplying the molar mass of
C:
mass Carbon = 3.49 x 10^-23 mol C (12 g / mol)
mass Carbon = 4.18 x 10^-22 g
Therefore the mass of one molecule of Cortisone is:
mass of 1 molecule Cortisone = 4.18 x 10^-22 g / 0.6998
mass of 1 molecule Cortisone = 5.98 x 10^-22 g per molecule
Converting this to mass per 1 mol of Cortisone, by using
again the Avogadro’s number:
mass of 1 mol Cortisone = (5.98 x 10^-22 g / molecule) (<span>6.022
x 10^23 molecules / mol)</span>
mass of 1 mol Cortisone = 360.10 g / mol = molar mass of
cortisone
Answer:
360.10 g / mol
An example of a monatomic cation would be Cs+. As this is the only cation that consists of a single atom.
