- uric acid, important or dangerous to your health?arrow_forwardBlack Forest Biologicals, a biotech startup, has a promising Alzheimer's drug candidate Compound SLT-88 entering Phase I trials this year. SLT-88 is the only product formed by the reaction of two precursor compounds A and B, both of which are quite expensive. The chief medicinal chemist of Black Forest is trying out different reaction conditions to minimize the cost of manufacturing SLT-88. In the table below are listed the initial and final amounts of A and B used under two different trial conditions, and also the actual amount of SLT-88 recovered each case. Complete the table by calculating the theoretical yield of SLT-88 and the percent yield of SLT-88.

- Synthetic natural gas (SNG) is a methane-containing mixture produced from the gasification of coal or oil shale directly at the site of the mine or oil field. One reaction for the production of SNG is: 4 CO (g) + 8 H2 (g) → 3 CH4 (g) + CO2 (g) + 2 H2O (g)Use the following thermochemical equations to determine ΔHo for the reaction as written. C(graphite) + 2 H2 (g) → CH4 (g) H2 (g) + 1/2 O2 (g) → H2O (g) C(graphite) + 1/2 O2 (g) → CO (g) CO(g) + 1/2 O2 (g) → CO2 (g) ΔHo = -74.8 kJ ΔHo = -285.8 kJ ΔHo = -110.5 kJ ΔHo = -283.0 kJ 5b.
