Alpha radiation is another type of radiation. alpha particles consist of two protons and two neutrons bound together into a particle identical to a helium nucleus. they have much less energy than either beta particles of gamma waves. suppose a geiger counter was placed 10 cm from an alpha emitter, and clicks were recorded for three minutes. based on the recorded data, predict the number of clicks you would detect on the far side of the aluminum shield.
a) 0 clicks
b) 2 clicks
c) 5 clicks
d) 10 clicks

While studying chemical reactions and conservation of matter, sarah's class conducted a variety of experiments. sarah and her lab partner found the mass of a wax candle and placed the candle in a flask. the students lit the candle and let it burn to completion. all that was left was wax and charred candle wick. per their teacher's instructions, the students found the mass of the products. their data can be seen in the data table. formulate a hypothesis the students could test to explain why the experiment did not support the law of conservation of matter. a) the students could repeat the experiment using different candles; there might have been a flaw in the candle. b) the experiment should be repeatable. the students should run several trials and then take an average of the after mass in each trial. c) the students should have someone in the class check their measurement skills as they repeat the experiment. they may have made an error using the balance. d) the students should burn the candle in a container that has some type of lid so that any gas that is a product of the reaction can be contained and massed. submit
