In an experiment, a student places 10 mL vinegar in a cup. The student places a thermometer in the cup, and then adds 30g baking soda to the cup. The resulting reaction decreases the temperature of the vinegar/baking soda mixture by 7 degrees C. What type of chemical reaction has occurred?

If you want to create an electrical current, which situation would produce a solution capable of this

What is the relation between concentration of reactants and the rate of chemical reaction?

Americium-241 undergoes fission to produce three neutrons per fission event. if a neutron-absorbing material is mixed in with this sample so that the rate of neutron production drops down to 1.8 neutrons per fission event, which will be effective at achieving a critical mass? check all that apply. remove a deflective shield surrounding the sample. remove absorbent material mixed in with the sample. compress the sample of americium-241.
