(Oh) 2.4.2 Mol Of Ca3p2
Assessment:
Answer the following item with the appropriate response. 1. What is a mole ratio? 2. What piece of information is needed to convert grams of a compound to moles of the same compound? 3. Phosphine (PH3) can be prepared by the hydrolysis of calcium phosphide, Ca3P2:
Ca3P2 + 6 H2O 3 Ca (OH)2 + 2 PH3 a) One mole of Ca3P2 produces 2 mol of PH3. b) One gram of Ca3P2 produces 2 g of PH3. c) 3 moles of Ca(OH)2 are produced for each 2 mol of PH3 produced. d) The mole ratio between phosphine and calcium phosphide is
2 mol PH31 mol Ca3P2 e) When 2.0 mol of Ca3P2 and 3.0 mol H2O react, 4.0 mol of PH3 can be formed.
Generalization:Activity: * Let the students work on a group of 3-4 members.
