Answer:
300kg
Explanation: The question says about 30%, so I think it is 300kg
Answer:
Temperature is a common type of controlled variable. If a temperature is held constant during an experiment, it is controlled. Other examples of controlled variables could be an amount of light, using the same type of glassware, constant humidity, or duration of an experiment.
Explanation:
The mole ratio is 4 NO2 to 3 O2; 4:3
Number of proton K=19
so, 42 - 19 =23
then the answer in 19 protons and 23 neutrons
We are given the chemical reaction and the amount of reactant used for the process. We use these data together to obtain what is asked. We do as as follows:
0.882 mol H2O2 ( 1 mol O2 / 2 mol H2O2 ) = 0.441 mol O2 produced
Hope this answers the question.
