Answer:
The correct option is: AgNO₃(aq) + KCl(aq) = AgCl(s) + KNO₃(aq)
Explanation:
Precipitation reaction is a chemical reaction that involves reaction between <em>two soluble salts to give an insoluble salt.</em> This <u>insoluble salt exists as a solid</u> and settles down.
Therefore, the solid formed in a precipitation reaction is known as the precipitate.
As the solid silver nitrate (AgNO₃) and solid potassium chloride (KCl) are <u>soluble in water</u>, therefore, their aqueous solutions are represented as AgNO₃(aq) and KCl(aq), respectively.
The precipitation reaction of AgNO₃(aq) and KCl(aq) gives an <u>insoluble salt, silver chloride (AgCl) and a soluble salt, potassium nitrate (KNO₃).</u>
The insoluble salt, <u>AgCl is called the precipitate</u> and is represented as AgCl(s). Whereas, the <u>soluble salt</u>, KNO₃ is represented as KNO₃ (aq).
<u>Therefore, the chemical equation for this precipitation reaction is:</u>
AgNO₃(aq) + KCl(aq) → AgCl(s) + KNO₃(aq)
Oxygen's atomic weight is 16.00 amu. 1 mole of oxygen is 6.02 x 1023 atoms of oxygen 1 amu = 1.661 x 10-24g What is the molar mass (g/mole) of oxygen? Molar mass (in grams) is always equal to the atomic weight of the atom! Molar mass (in grams) is always equal to the atomic weight of the atom!
I dont know sorry i wish i could help you
Answer:
Silver and copper
Explanation:
Siliver
Electrical conductivity=62000000(s/m)
Boiling point=2162
Melting point=961.78
Phase=solid
Copper
Electrical conductivity=59000000(s/m)
Boiling point =2927
Melting point=1084.62
Phase=soild
Metals like gold, silver and copper are drawn into thin wire and are used in an electric circuit because of their high electrical conductivity
Mostly Siliver and copper are used since using gold is much expensive.
A sample of material is found to have a mass if 33.03 grams (g), and a volume of 2.624 ml, hence the metal is Silver.
∴ Silver = 12.59 g/mL
The elements of group 11 (Cu, Ag, and Au) are called coinage metals because they are used in minting coins. These metals are malleable. They have the ability to get converted into sheets.
The coinage metal comprise, at a minimum, those metallic chemical elements which have historically been used as components in alloys used to mint coins.
The coinage metals have the highest electrical and thermal conductivities of all the metals, and they are also the most ductile and malleable.
