Tyler has mixed two different solutions. both of the solutions are bases. tyler would like to determine which of the bases makes the most effective cleaning product. he designs the following experiment: place the bases in separate spray bottles. use the first base to clean a dirty kitchen sink. use the second base to clean a tub. rate how well each base cleaned the surfaces. report the results. in looking at tyler's experiment, what did he do wrong?

According to the loco mass the mass of reactants and products

Which of these statements are true about scientific theories and hypothesis

Four different thermometers were used to measure the temperature of a sample of pure boiling water. the measurements are recorded in the table below. thermometer temperature reading 1 temperature reading 2 temperature reading 3 w 100.1°c 99.9°c 96.9°c x 100.4°c 102.3°c 101.4°c y 90.0°c 95.2°c 98.6°c z 90.8°c 90.6°c 90.7°c the actual boiling point of pure water is 100.0°c. what can be concluded from the data about the reliability and validity of the thermometers?
