the subscript 2 after the H indicates that the hydrogen molecule contains two (2) atoms of hydrogen
he told that science is science and sciance cannot be science if sceince if science is not science and if science did not come from science the science will not be science
12.01 g NH3 = 0.667 mol NH3 = 1 mol H2 = 2.0 g H2
By Pythagoras theorem ,we can say that h2=b2+p2 h2= 12 ^2 +14 ^2=340 h= sqrt (340)=18.4 cm
science is science!!
dour science is science obviously
H2+ has a stronger bond than H2. The addition of a positive charge to the H2 molecule increases the attraction between the two hydrogen atoms, resulting in a stronger bond.
The product of H2 is hydrogen gas (H2) composed of diatomic molecules.
Its H2
Some cool experiments like k +H2O, bringing a balloon full of h2 near a flame, etc.
"h" typically represents enthalpy, which is a measure of the total heat content in a system. "H2" represents a molecule of hydrogen gas, which consists of two hydrogen atoms bound together. So "h h H2" could refer to the enthalpy change associated with the reaction involving hydrogen gas.
H2 is the elemental form of hydrogen.
1 mole H2 = 2.016g H2 = 6.022 x 1023 molecules H210g H2 x 1mol H2/2.016g H2 x 6.022 x 1023 molecules H2/1mol H2 = 3 x 1024 molecules H2 (rounded to 1 significant figure)
Given/Known:1mole of H2 = 2.01588g H21mole of H2 = 6.022 x 1023 molecules H21) Convert molecules of H2 to moles of H2 by doing the following calculation.9.4 x 1025 molecules H2 x (1mol H2/6.022 x 1023 molecules H2) = 156mol H22) Convert the moles of H2 to mass in grams of H2.156mol H2 x (2.01588g H2/1mol H2) = 314g H2
NaCl + H2.
