Time and concentration data were collected for the reaction A⟶products t (s) [A] (M) 0 0.52 20 0.43 40 0.35 60 0.29 80 0.23 100 0.19 The blue curve is the plot of the data. The straight orange line is tangent to the blue curve at t=40 s. A plot has the concentration of A in molar on the y axis and time in seconds on the x axis. A curve contains the points (0, 0.52), (20, 0.43), (40, 0.35), (60, 0.29), (80, 0.24), and (100, 0.20). A line touches the curve at (40, 0.35) and has a y intercept of (0, 0.48). Approximate the instantaneous rate of this reaction at time t=40 s.

Aside from human impact, which of the following causes less water vapor production over a small area? (2 pderivartin

Ase your answer to this question on the information below. hydrocarbons and fissionable nuclei are among the sources used for the production of energy in the united states. a chemical reaction produces much less energy than a nuclear reaction per mole of reactant. the balanced chemical equation below represents the reaction of one molecule of a hydrocarbon with two molecules of oxygen. chemical equation: ch4 + 2o2 → co2 + 2h2o + 1.48 × 10−18 jthe nuclear equation below represents one of the many possible reactions for one fissionable nucleus. in this equation, x represents a missing product. nuclear equation: write an isotopic notation for the missing product represented by x in the nuclear equation.

Imagine that you push on a large rock. at what point does your effort change the rock’s mechanical energy?
