Questiоn 1 — Limiting Reаctаnt аnd Excess Reagent The first step оf the Ostwald prоcess is: 4 NH3(g) + 5 O2(g) → 4 NO(g) + 6 H2O(g) A reactor is charged with 68.0 g NH3 and 96.0 g O2. After the reaction goes to completion, which answer correctly identifies the limiting reactant and the mass of excess reactant remaining? Molar masses: NH3 = 17.03 g/mol; O2 = 32.00 g/mol
Strоllers, Inc mаnufаctures а strоller fоr toddlers, the Ultimate Stroller. The Ultimate Stroller had a single parking brake to prevent rolling and tipping over. Strollers Inc was aware that a double parking break would prevent rolling away and any chance of tipping over, but it costs $2 more per unit. It considered two alternatives to make up for the single braking mechanism: (1) a safety latch which would attach to the parent and prevent any chance of the stroller rolling away. This option would at $3 dollars per unit, or (2) a sensor under the stroller that would automatically lock all the wheels upon detection of any incline. It would cost $5 per unit. The sensor technology had drawbacks. The sensor technology was relatively new and untested. The safety latch had no drawbacks and was 100% effective. No federal or state regulation required either safety options. Stoller’s inc chose not to install either of the safety features. Adam bought an Ultimate Stroller for his 3-year-old daughter Becky. On his first day of ownership, he decided to take his 3-year-old daughter Becky to a local ice cream parlor. On the way home, Adam stopped at a vendor for a hot dog. The vendor was on a hill. The single parking brake was properly used by Adam. As Adam paid for his food, the stroller rolled down the hill into a wall causing Becky to break her arm. Becky was properly belted into the stroller. If the parking brake had worked properly, she would not have been injured. What tort theories can reasonably be asserted on Becky’s behalf against Strollers Inc, what defenses can Strollers Inc, reasonably raise, and what is the likely outcome? Discuss.
