Suppose you wanted to calculate the heat of reaction for the formation of ammonia gas and gaseous hydrochloric acid from solid ammonium chloride.
a. write a balanced equation for this reaction.

Consider this initial-rate data at a certain temperature for the reaction described by

Which sample at stp has the same number of atoms as 18 liters of ne at stp

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
