Im taking my finals! worth 34 pointsthe table shows the rate of reaction for two unknown time intervals during the course of a reaction. reaction ratestime intervals (s) rate (m/s)t1 3.2 × 10−3t2 3.9 × 10−3which of the following is true for the two time intervals? t1 is longer than t2, and the concentration of reactants at the end of t1 is higher than that of t2. t1 is longer than t2, and the concentration of products at the end of t1 is higher than that of t2. t1 is shorter than t2, and the concentration of reactants at the end of t1 is lower than that of t2. t1 is shorter than t2, and the concentration of products at the end of t1 is lower than that of t2.

What’s the scientific notation for the number 6,840,000,000

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.

When 225mg of anthracene, c14h10(s), was burned in a bomb calorimeter the temperature rose by 1.75k. calculate the calorimeter constant. by how much will the temperature rise when 125mg of phenol, c6h5oh(s), is burned in the calorimeter under the same conditions? (δch< (c14h10,s)=–7061 kj mol−1.)
