Neutral water<span> has the same concentration of Hydrogen ions which are also called the H+ and the Hydroxide ions, which also could be referred to as OH-. A neutral water is considered to have a pH level of 7 wherein it stands between the acid level and the base level which makes it suitable for human consumption.</span>
Answer:
The analogy that best describes is "The planets go around the sun."
Explanation:
The best analogy that suggests that electrons moves round the nucleus in an atom is the Bohr model. According to Neil Bohr, Based on Rutherford's model, he suggested that the extra nuclear part consists of electrons.
These electrons are in the spherical orbits called shells or energy levels around the nucleus.
The nucleus is the tiny massive center of the atom.
Transition of electrons takes place from one level to another.
Answer:
0.034 M
Explanation:
1/[A] = kt + 1/[A]o
[A] = ?
k= 0.04556
t= 10.0 minutes or 600 seconds
[A]o = 0.50 M
1/[A] = (0.04556 × 600) + 1/0.50
[A] = 0.034 M
Answer:
Independent variable: AMOUNT OF SUNLIGHT
Dependent variable: HEIGHT OF PLANTS
Experimental group: PLANTS KEPT UNDER BRIGHT SUN LAMPS ALL NIGHT
Control group: PLANTS THAT RECEIVED NORMAL AMOUNT OF SUNLIGHT
Explanation:
Independent variable refers to the variable that is manipulated or changed in an experiment in order to effect a measurable response. In this case, the independent variable is the VARYING AMOUNT OF SUNLIGHT.
Dependent variable is the variable that the experimenter measures or the variable that responds to changes made to independent variable. The dependent variable in this case is the HEIGHT OF PLANTS measured.
Experimental group is the group in an experiment that receives the experimental treatment. In this case, the PLANTS KEPT UNDER BRIGHT SUN LAMPS ALL NIGHT is the experimental group.
Control group is the group that does not receive any experimental treatment/independent variable. In this case, the PLANTS THAT RECEIVED NORMAL AMOUNT OF SUNLIGHT is the control group.
