If 10.45 g of aluminum are reacted with 66.55 g of copper (II) sulphate, aluminum sulphate and copper are formed.
a.Which reactant is in excess?
b. Calculate the mass of copper formed.

Predict the shape of brf4^-1 using VSEPR theory

3. Given the following thermochemical equations,
C2H2(g) + 5/2 O2(g) → 2CO2(g) + H2O(l) ∆H = -1299.5 KJ
C(s) + O2(g) → CO2(g) ∆H = -393.5 KJ
H2(g) + ½ O2(g) → H2O(l) ∆H = -285.8 KJ
Calculate ∆H for the decomposition of one mole of acetylene, C2H2(g), to its elements in their stable state at 25oC and 1 atm.

4. Calculate
a. q when a system does 54J of work and its energy decreases by 72 J
b. ∆E for a gas that releases 38J of heat and has 102J of work done on it.

a) Calculate the energy required to excite a particle in a cubic box of edge length 1A^° from its ground state to its first excited state. b) what us the reason for the increase in the spectral frequency as be increases?

a) draw the boron-haber cycle of NaCl
b) draw the mo energy level diagram of NO and calculate it's bond order.

a) Predict the shape of brf4^-1 using caper theory.
b) write the postulates of bohr's atomic theory

A closed system initially containing 1.000 × 10-3 M H2 and 2.000 × 10-3 M I2 at 448℃ is allowed to reach equilibrium. At equilibrium, the HI concentration is 1.87 × 10-3 M. Given that the reaction equation is H2(g) + I2(g) ↔ 2 HI(g), find:
a. Equilibrium concentrations of the two reactants
b. Kc of the reaction taking place.

For N2(g) + 3 H2(g) ↔ 2 NH3(g), Kp = 4.34 × 10-3 at 300℃. What is Kp or the reverse reaction?
