Weegy: Sir/Madam, The mass of the original sample is "55.00 grams" (More)

Weegy: aprox 97 g (More)

Weegy: 2Na + Cl2 - - -> 2NaCl Mass of Cl2: 96.6 g * 71 / 2 * 23 = 149 g (More)

Weegy: Initial sample 960g after 1 half life 480g after 2 half-lives 240g after 3 half-lives 120g after 4 half-lives 60g after 5 half-lives 30g The sample went through 5 half-life cycles in 15 minutes, so 1 half-life is 3 minutes. [ The official half-life is 3.10m. ] User: Explain the difference between a physical equilibrium and a chemical equilibrium. Weegy: chemical equilibrium: A condition in which a chemical reaction is occurring at equal rates in its forward and reverse directions, so that the concentrations of the reacting substances do not change with time. [ Also known as equilibrium. Physical equilibrium: -the changes that occur are physical processes. H2O (l) H2O (g) Water molecules continue to evaporate from the liquid, but an equal number condense during the same time interval (i.e., the rates are equal) ] (More)

Weegy: Please tell us why you think our answer was wrong. Thank you. (More)
