Given the equation representing a system at equilibrium:
N204(g) = 2NO2(g)
Which statement describes the concentration of the two gases in this system.
1) The concentration of N2O4(g) must be less than the concentration of NO2(g)
2) The concentration of N2O4(g) must be greater than the concentration of NO2(g)
3) The concentration of N2O4(g) and the concentration of NO2(g) must be equal
4) The concentration of N2O4(g) and the concentration of NO2(g) must be constant

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.

Ahydrogen atom has 1 electron. how many bonds can hydrogen form? a) 1 b) 2 c) 3 d) 4 e) 5

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
