How old is a rock that in which 75% of the potassium-40 has turned into argon-40?
How old is a rock that in which 75% of the potassium-40 has turned into argon-40? According to modern scientific dating techniques, approximately how old is the solar system? A rock sample from the moon includes a mineral that contains small amounts of the radioactive isotope Potassium-40 and its daughter element Argon-40 (half-life of 1.3 […]
Which of the following has the largest effective nuclear charge?
Which of the following has the largest effective nuclear charge? sodium cation What happens to the effective nuclear charge down a group? In general, ionization energy increases across a period and decreases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant. Down a group, the number of energy levels […]
Which describes the formation of a precipitate?
Which describes the formation of a precipitate? Precipitate: In chemistry, a solid formed by a change in a solution, often due to a chemical reaction or change in temperature that decreases solubility of a solid. In meteorology a precipitate is liquid or solid water (rain, snow, etc.) falling from the sky. What other name can […]
What is the dimensional formula of radiation energy?
What is the dimensional formula of radiation energy? Or, E = [M] × [L1 T-1]2 = M1 L2 T-2. Therefore, energy is dimensionally represented as M1 L2 T-2. Does light have a pressure? While most experiments have found that light exerts a pulling pressure, in a new paper physicists have, for the first time, found […]

What are examples of exergonic and endergonic reactions?
What are examples of exergonic and endergonic reactions? Often, one chemical reaction feeds the next and endergonic reactions are coupled to exergonic reactions to give them enough energy to proceed. For example, firefly bioluminescence results from endergonic luminescence by luciferin, coupled with exergonic ATP release. What causes a reaction to be spontaneous? A spontaneous reaction […]
