Below is a chemical equation along with a verbal description of the reaction Verbal description: Gaseous sulfur trioxide is added to liquid water to produce aqueous sulfuric acid. Equation: SO3(g) + H20 (l) > H2S04(aq) Questions: 1.) Was matter lost or gained during this reaction? Explain how you could prove this be taking measurements. 2.) The left side of the equation shows one atom of S, two atoms of H, and four atoms of O. How many atoms of each element are on the right side of the equation? How does this provide evidence for the law of conservation of mass?

What happens when an acid dissolves?

In a heat of an engine, if 700 j enters the system, and the piston does 400 j of work what is the final internal (thermal) energy of the system if the initial energy is 1,500 j
