This is a case of metric system of measurements. The scale of the metric system only differs by a factor of 10. The scale (from greatest to least) is kiloliter, hectoliter, dekaliter, liter, deciliter, centiliter and milliliter. If the unit is 150 dL, and you want to find the equivalent dkL measurement, just move the decimal point 2 decimals places to the left (just follow the scale). The same procedure is done for the other metric units.
150 dL = 1.5 dkL
150 dL = 15 L
150 dL = 1,500 cL
150 dL = 15,000 mL
From the choices, the answer is letter C.
C, the amount of oxygen produced is the dependent variable since that is what is being measured and it is dependent on which substance is being tested
Answer:
the answer is option D
Explanation:
exothermic reaction takes place when the energy required to break the bonds in the reactants is less than the energy released when new bonds are formed in the products.
