No. The mass is released into the air.
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)
Answer:
<h3>The answer is 2.0 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 4 g
volume = 2 cm³
We have
We have the final answer as
<h3>2.0 g/cm³</h3>
Hope this helps you
(191.0 x 37.39) +(193.0 x62.42)
———————————————-
37.39+62.42
= 192.25 (2dp)
The density of the sphere is 0.0713 g/cm^3.
<h3>What is density? </h3><h3> </h3>
The density of a substance indicates how dense it is in a particular area. Mass per unit volume is the definition of a material's density. In essence, density is a measurement of how closely stuff is packed. It is a special physical characteristic of a certain thing.
The Greek scientist Archimedes made the discovery of the density principle. If you are familiar with the formula and the relevant units, calculating density is simple. The letter D can also be used to signify density instead of the symbol.
The circumference of the sphere = 32.5 mm
2 (pi) r
2 × 22/7 × r = 32.5
44/7 × r = 32.5
44 × r = 32.5 × 7
44 × r = 227.5
r = 227.5/44
r = 5.2
Now, V = (4/3) (pi) r^3
V = 4/3 × 22/7 × (5.2)^3
V = 4/3 × 22/7 × 140. 608
V = 589. 21 mm
V = 58.921 cm^3
Density = 4.20/58.92
D = 0.0713 g/cm^3
Therefore, the density is 0.0713 g/cm^3.
