Based on the formulas, select the compounds below that are covalent: KBr SiF4 Al2O3 CO2 NaCO3 S7O2 PCl3 Fe3N2 H2O S2F10

Which statement correctly describes a physical change? involves breaking and creating chemical bonds but not changing a phase may involve a change in phase but does not involve a change in the molecular structure may involve converting two or more

Observe the reaction between N2 and H2 to make NH3. N2 (g) + H2 (g) → NH3 (g) If 2 molecules of N2 react with 3 molecules of H2, determine the number of molecules of NH3 that could form from each starting material.

How will increasing the pressure on the system affect this equilibrium reaction? 2H2 (g) + O2 (g) - > 2H2O (g)
