Please help I have 15 min to respond this 1. Magnesium is the limiting reactant in this experiment. Calculate the theoretical yield of MgO for each trial.

2. Determine the percent yield of MgO for your experiment for each trial.

3. Determine the average percent yield of MgO for the two trials.

Which of the following observations indicates that an atom has neutrons? some uncharged particles are scattered by a beryllium atom when it hits a gold foil. some uncharged particles bounce back from a gold foil when it is bombarded with alpha particles. a radiation consisting of uncharged particles is emitted when alpha particles strike beryllium atoms. a radiation which attracts electrons is produced when a beryllium atom is bombarded with alpha particles.
