A chemist cаrries оut this reаctiоn in the lаbоratory, using 4.31 grams of zinc and an excess of sulfur: Zn + S --> ZnS From the balanced equation, she calculates that she should obtain 6.41 grams of zinc sulfide. However, she isolates only 5.85 g of product. What is her percent yield for this reaction?
Rоbert is а 72 yr оld mаn аdmitted tо the hospital diagnosed with Congestive Heart Failure presenting with increased SOB, productive cough, 10# weight gain in past 2 weeks, 3+ pitting edema in LEs, fatigue and weakness. PMH includes: L LE transtibial amputation, obesity, HTN, hyperlipidemia, MI x 2 (2008, 2011), PTCA with stent 2011. Home meds include: metoprolol (Beta Blocker), lisinopril (ACE inhibitor), Lasix (diuretic), and aspirin (antiplatelet/anticoagulant). SH: Married, lives in 2 story home with 2 STE without railing, bed/bath up 14 steps with railing on R side as you go up. Has half bath on first floor. Pt is retired. Pt is independent with his prosthesis. Hobbies include golf, computer, reading, and going to grandchildren’s’ sporting events. He wears glasses all the time and wears hearing aids bilaterally PT Evaluation: UE/LE ROM WNL in available joints. Strength = 4+/5 in available musculature except bilateral hip extension= 4-/5. Pt presents with 3+ pitting edema in B LEs. Sensation—pt with increased sensitivity to light touch and pressure in bilateral LE’s. Functional Mobility: Supine to sit with minimal assist, sit to stand with rolling walker with min assist, NWB L LE. Pt is unable to wear his prosthesis due to edema. Gait training with RW x 10’ with min A, NWB L LE. Pt had 2 standing rest breaks x 20 seconds each due to fatigue and SOB. Stairs not assessed due to SOB and fatigue. Vital signs: Pre-activity (sitting) BP 136/80 mmHg HR 90 bpm SpO2 on 2L 99% During activity (gait) BP 120/75 mmHg HR 105 bpm SpO2 on 2L 91% RPE 5/10 Post-activity (sitting) BP 125/76 mmHg HR 100 bpm SpO2 on 2L 95% Line management: Foley catheter, oxygen 2 L per nasal cannula, IV R forearm The primary reason Robert takes an aspirin (antithrombotic) is:

He is NWB L UE. The assistive device that is best for Robert is:
