the mole concept :
a mole (mol) is defined as the amount of substance that contains as many atoms, molecules, icons, electrons or any other elementary entities as there are carbon atoms in exactly 12 gm of. the number of atoms in 12gm of is called Avogadro's number.
I'm not sure about muscular mass sorryyyy
Answer: In chemistry, reactivity is the impetus for which a chemical substance undergoes a chemical reaction, either by itself or with other materials, with an overall release of energy.
Explanation:
Answer:
About 366 joules
Explanation:
PEg = mgh
PEg = 4.24(8.81) * 9.81
PEg = 37.3544 * 9.81
PEg = 366.446664, which rounds to 366 joules.
On the left (reactant) side you have 6 N-H bonds and 1 Cl-Cl bond
<span>On the right (product) side you have 4 N-H bonds, 1 N-N bond and 2 H-Cl bonds </span>
<span>Add up the bond energies for each side (multiplying by the number of bonds) and calculate the difference for your ΔHº</span>
It has bent geometry, which is similar to H2O, with the same angle of 109.5 degrees between 2 single H-S bonds.
