Answer:
KHP + NaOH ⟶ KNaP + H₂O
Explanation:
The H in KHP is the acidic hydrogen. The OH⁻ in NaOH neutralizes it and converts it to H₂O.
The balanced equation for the reaction is
KHP + NaOH ⟶ KNaP + H₂O
When we convert the given mass in grams and volume in liters to m/v percent, we recall that m/v percent is expressed as grams/100 milliliters. In this case the expression becomes (50 grams/ 2500 L)*(0.1L/100ml), that is equal to 0.002 grams/ 100 mL. Hence the the concentration is equal to 0.2 m/v percent.
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)
This dissociation occur because:
O had to bond with H due to the Hydrogen bonding rule, which will form OH~ (Hydroxide).
K is more attracted to Hydroxide than Cl, so it will depart Cl and bond with OH~.
that leaves a H and a Cl, which one has a positive charge and the other has a negative, so they will bond and form Hydrochloric Acid.
Just count the number C’s and H’s
