A. The mass is exactly 255.00 grams.
B The mass is slightly less than 255 grams.
C. The mass is slightly more than 255 grams
D. The mass is not exactly 255 grams, but it is impossible to tell whether the mass is greater than or less than 255 grams

The rate constant for the reaction below is 6.2 x 10−5 mol l−1 s −1. if the initial concentration of a is 0.0500 m, what is its concentration after 115 s?

What are the trends and exceptions to the trends in electron affinity?

The goal of this experiment was to answer the question "what is the effect of a gas' temperature on its volume? " you formulated the hypothesis below. hypothesis: if a fixed amount of gas is heated, then the volume will increase because the heat will cause the molecules of gas to move faster and further apart. to test this hypothesis, you changed the of the gas between 0 and 100°c (273 and 373 k) and calculated the resulting of the gas.
