b) If 40.0 grams of phosphorous acid were heated to reaction, what mass of phosphine, in grams, would be produced? Don't forget significant digits!
Added by Chad S.
Step 1
The reaction of phosphorous acid (H3PO3) with heat to produce phosphine (PH3) and water (H2O) can be represented as: \[ 4H_3PO_3 \rightarrow 3PH_3 + 6H_2O \] Show more…

7. (a) How many grams of phosphine (PH3) can form when 40 g of phosphorus and 38.0 L of hydrogen gas react at 18 °C? (b) If 21.3 g of PH3 forms, what is the percent yield? P4(s) + H2(g) → PH3(g) [unbalanced] a) 36.0 g PH3, 59.2% yield b) 43.8 g PH3, 48.6% yield c) 11.0 g PH3, 51.5% yield d) 54.1 g PH3, 39.4% yield e) 81.1 g PH3, 26.3% yield
