Answer:
Moles = Molecules / (6.0221415 x 10^23)
Explanation:
A is the answer
In an ozone molecule, the three atoms must be connected, so there must at least be a single bond between them. Place
dots in pairs around the oxygen atoms until each oxygen atom has eight valence electrons, starting with the atoms on the
outside and doing the central atom last if there are enough. Do not exceed the total number of valence electrons
identified in part A. Remember that the dashes between the oxygen atoms, which represent single bonds, each indicate
the presence of two valence electrons
Answer:
a) O²⁻ + H₂O <-----> OH⁻ + OH⁻
Acid = H₂O
Base = O²⁻
Conjugate Acid = OH⁻
Conjugate Base = OH⁻
b) HClO₄ + H₂SO₄ <-----> ClO₄⁻ + H₃SO₄⁺
Acid = HClO₄
Base = H₂SO₄
Conjugate Acid = H₃SO₄⁺
Conjugate Base = ClO₄⁻
c) NH₃ + HNO₃ <--> NH4⁺ + NO₃⁻
Acid = HNO₃
Base = NH₃
Conjugate Acid = NH4⁺
Conjugate Base = NO₃⁻
Explanation:
- Acids are molecules or ions capable of donating a proton (H⁺).
- Bases are molecules or ions that readily accept the H⁺ from acids.
- Conjugate Acids, according to the Brønsted–Lowry acid–base theory, are chemical compounds formed after the reception of a proton (H⁺) from an acid by a base.
- Conjugate Bases, Brønsted–Lowry acid–base theory, are the leftovers from when acids donate their proton (H⁺).

Explanation:
Hello,
The question above requires us to classify certain properties which may either fall into physical or chemical properties of that matter.
Physical properties are properties which are of intrinsic value and has no influence on the chemical nature of the substance while chemical properties are those that influence the chemical nature of the substance.
Physical properties can be measured or calculated while chemical properties of a substance is very difficult to measure.
a). Silver has a shiny luster is an example of "physical property" because the shiny nature of silver has no chemical importance.
b). Silver metal has a density of 10.49 g/cm³ is also a "physical property" because density is a physical property of a material.
Density is ratio between mass and volume which are both physical properties since they can be measured.
c). Silver metal and Chlorine gas produce Silver chloride (AgCl) is a "chemical property" since it involves combining of two elements and they both lose their original chemical identity after the reaction.
d). Silver metal has a melting point of 1235°C is a "physical property"
e). Silver metal conducts electricity is a "chemical property" since conduction of electricity are done by the availability of mobile electrons in its electron cloud.
f) silver metal gives no reaction to acid is also an example of "chemical property"
