3. Jax designs an experiment to determine how the amount of sodium chloride affects the boiling point of water. He adds 19,5 g, and 10 g of sodium chloride to three different beakers, each containing 100 mL of water. There is a fourth beaker that contains 100 ml water without any sodium chloride. He heats each of the samples on a Bunsen burner and measures the boiling point
with the same thermometer. Which of the following is the dependent/responsive variable in the experiment?
O The thermometer
O The amount of sodium chloride.
O The temperature at which the water boils.
O The amount of water,

What is the volume of the fluid in the graduated cylinder with accuracy and measured to the correct degree of precision? 41.2 ml 42.0 ml 41.23 ml 41.89 ml

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.
