Give the ΔH value for the decomposition of phosphorus pentachloride as shown in the reaction PCl5(g)+67 kJ→PCl3(g)+Cl2(g)

Since heat is added to the reactant it's an endothermic reaction, so the sign on ΔH is positive so:ΔH = +67 kJ

Enter a balanced chemical equation for the reaction of solid rubidium with liquid water. Express your answer as a chemical equation. Identify all of the phases in your answer.

Rubidium is an alkali metal in the same group (Group I) as sodium and as one goes down the group the ionization energy decreases.Hence Rb also reacts with water leading...

4moles of an equimolar mixture of cl2and N2 are added to a vessel containing 1 mole of PCl5,2moles of PCl3,and 3 moles of Cl2 at equilibrium,the mole fraction of PCl5 at equilibrium will be?

Cl2 + PCl3 = PCl52 mol Cl2 + 2 mol PCl3 = 2 mol PCl5So, finalCl2 = 3 mol;N2 = 2 mol;PCl3 = 0 mol;PCl5 = 3 molTotal = 8...

2Na+Cl2→2NaCl When 10.0 g of Cl2 is used, the reaction produced 12.5 grams NaCl. What is the % yield of the reaction? Use the following molar masses: Cl2=70g/mol and NaCl=58g/mol.

2Na + Cl2 → 2NaClThe theoretical yield of the reaction:m(NaCl) = m(Cl2) × 2 Mr(NaCl) / Mr(Cl2) = 10.0 g × 2 × 58 g/mol / 70 g/mol = 16.6...

Metal: 1s22s22p63s23p64s2; nonmetal: 1s22s22p63s23p3 Express your answers as a cation, an anion, and a chemical formula separated by commas.

The metal is Calcium, and the nonmetal is Phosphorus. Normally, the electron shell should be complete to stabilize the atom: Ca2+, P3-, Ca3P2
