One of the most common causes of inaccurate melting points is heating of the melting-point apparatus too rapidly. under these circumstances, how will the observed melting point compare with the true melting point?

If 90.0 grams of ethane reacted with excess chlorine,how many grams of dicarbon hexachloride would form

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.

Which of these is not an example of chemical weathering? a. iron-rich mineral rusting b. feldspar turning into clay c. limestone reacting with acid d. granite breaking up into sand
