How did Rutherford interpret the following observations made during his a-particle scattering experiments? (a) Most a particles were not appreciably deflected as they passed through the gold foil.
(b) A few a particles were deflected at very large angles.
(c) What differences would you expect if beryllium foil were used instead of gold foil in the a-particle scattering experiment?

Only one reactant yields 2 or more products. meaning you will only have 1 product and it will break down into 2 or more products. eg. h2o -> h2 + o2

Answer : option c) heat is released during the process.explanation :

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

257 grams h2o i think

Idont really know sorry
