Hydrogenation of double and triple bonds is an important industrial process. calculate (in kj/mole) the standard enthalpy change \delta δ h° for the hydrogenation of ethyne (acetylene) to ethane. just enter a number (no units). h–clatex: \equiv ≡ c–h(g) + 2h2(g) \longrightarrow ⟶ h3c–ch3(g)

Agas can holds 2.0 gal of gasoline. what is this quantity in cubic centimeters?

Asolution contains 180 g of glucose (c6h12o6) and 162 g of water. what is the mole fraction of glucose?

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
