How many grams of hydrogen (H2) can be produced from 98 of H2SO4? (MM 98 g/mol)?

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.

According to le chatelier’s principle, a system in chemical equilibrium responds to stress by shifting the equilibrium in a direction that reduces the stress. normalizes the stress. increases the stress. changes the stress.

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
