Write and balance the equation for the burning of an unknown hydrocarbon, C4H9 in air.
For an electron if the uncertainty in velocity is Δ v , the uncertainty in its position( Δ x ) is given by: (1) hm/ 4 Π Δ b (2) 4 Π / hm Π v
For cations build from metals in early groups in the periodic table the complexing strength with halide ions follows the sequence whereas with many post-transitio
Q. Describe the Half -Life property of radioactive decay? Ans. The decay of a nucleus is a random event. It is impossible to predict which nucleus will decay and when.
The effects that temperature has on the equilibrium position of a reaction can also be explained by using Le Chtelier's Principle. Recall that in an exothermic reaction, heat i
