2.heating
3.adding some oppositely charged colloids
Answer:
five electrons
Bromine (Z=35), which has 35 electrons, can be found in Period 4, Group VII of the periodic table. Since bromine has 7 valence electrons, the 4s orbital will be completely filled with 2 electrons, and the remaining five electrons will occupy the 4p orbital
Answer:
- <u>Second choice: </u><em><u>How does the position of the Sun, moons, planets and stars affect a person's personality traits and daily behavior patterns?</u></em>
<u></u>
Explanation:
Science or scientific investigations deal with objective phenomena; this is phenomena which can be described by using objective measurements.
The effect of the position of the Sun, moons, planets and stars on a person's personality and daily behavior patterns is not a scientific question because none scientific field deals with that kind of questions.
Only, a pseudoscience, this is a set of beliefs that have not been scientifically proved, may deal with a question about the effect of the position of some heavenly objects can affect a person's personality traits and daily behavior of patterns.
On the other hand, the aspects deal with in the other questions (the mass of a toy car, the speed down a ramp, the heating from different type of pans, how different type of chemicals remove the cell wall of a plant cell) are measurable and testable (falsifiable), which make them objects of science (like physics, chemistry, and biology)
