Hydrogen Cyanide gas is produced industrially by this reaction: 2 CH4(g) + 3 O2(g) + 2 NH3(g) --> 2 HCN(g) + 6 H2O(g)

What volumes of O2(g) and NH3(g) are needed to react with 8.0 L of CH4(g) at STP?

Compare and contrast physical changes with chemical changes.

Predict whether the changes in enthalpy, entropy, and free energy will be positive or negative for the boiling of water, and explain your predictions. how does temperature affect the spontaneity of this process?

Which statement explains why the bonds between non metals tend to be covalent? the bonds are found to be nondirectional they have large differences in electronegativity they have small differences in electronegativity they have ions that produce an electrostatic pull
