Answer:
A. 1.585 x 10^-12 M.
B. 2.512 x 10^-12 M.
Explanation:
A.
citric acid: pH 2.20
pH + pOH = 14
pOH = 14 - 2.20
= 11.80
Remember, pOH = - log [OH]
[OH] = 10^-pOH
= 10^-11.8
= 1.585 x 10^-12 M
B.
Household vinegar: pH 2.40
pH + pOH = 14
pOH = 14 - 2.40
= 11.60
Remember, pOH = - log [OH]
[OH] = 10^-pOH
= 10^-11.6
= 2.512 x 10^-12 M
The parasite obtains food and shelter from the host. Parasitism mode of life ensures food lodging and meals. PREDATION (+/-) is a a relationship between a Predator and a Prey in which the predator is a free living organism which catches and kills another species for food. They do not get shelter from pre
There is 3 subatomic particles that form an atom 1.) Protons 2.) Neutrons 3.) Electrons and they are located in the Nucleus :)
1. Density is calculated by dividing the object's mass by the volume it occupies.
2. The volume may be determined by water displacement method.
3. D = m/v
Substituting the known values,
D = 10.0 g / 15.625 cm³ = 0.64 g/cm³
Answer:
The nucleus of an atom is made up of positively charged protons and neutrally charged neutrons. The nucleus determines which element an atom is, based on the number of protons. For example, only Oxygen has 8 protons, Carbon has 6 protons, etc. The nucleus is about 1/100,000 of the size if the whole atom.
