Olivia wanted to conduct research at the zoo. She observed the lions, giraffes, zebra, baboons, and the elephants. She observed each species for 90 minutes and wrote down everything she saw them do. When she went home, she summarized what she observed in a chart. The next day, Olivia told her best friend that she had completed a full scientific experiment at the zoo. Why is this statement of Olivia’s incorrect?

To find the enthalpy of a reaction in the lab, you measured the of the reactants and the change during the reaction.

The equation picture below shows which type of nuclear reaction u 235 + n x e 134 + sr 100 + 2n

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.
