Classify each of the following reactions as their type such as synthesis reactions and else. 1- N2(g) + 3H2(g) ⎯→ 2NH3(g)

2- 2Li(s) + 2H2O(l ) ⎯→ 2LiOH(aq) + H2(g)

3- 2NaNO3(s) ⎯→ 2NaNO2(s) + O2(g)

4- 2C6H14(l ) + 19O2(g) ⎯→ 12CO2(g) + 14H2O(l )

5- 2HCI(aq) + FeS(aq)→ FeCI2(aq) + H2S(g)

6- 2Fe2O3 + 3C → 4Fe + 3CO2

Water (2510 g ) is heated until it just begins to boil. if the water absorbs 5.09×105 j of heat in the process, what was the initial temperature of the water?

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization.a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution.part bcalculate the percent ionization of ha in a 0.010 m solution
