What is the density of this problem

Chemistry
1 answer:
Luda [366]3 years ago
4 0

Answer:

Density of copper = 8.9 g/cm³

The density of liquid mercury is 13.6 g/cm³ which means mercury is denser than copper so copper will float on liquid mercury.

Explanation:

Given data:

weight of copper metal = 1896 g

Dimensions of block = 8.4 cm, 5.5 cm, 4.6 cm

Density of copper = ?

Will it float to the liquid mercury = ?

Solution:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

volume of coper metal =  8.4 cm × 5.5 cm × 4.6 cm

volume of coper metal =212.52 cm³

d = 1896 g/ 212.52 cm³

d = 8.9 g/cm³

The density of liquid mercury is 13.6 g/cm³ which means mercury is denser than copper so copper will float on liquid mercury.

In the apparatus of the electrochemical cell, the seawater is an example of an electrolyte.

<h3>What is an electrolyte?</h3>

An electrolyte is a component of the electrochemical cell that is a solution of solvent or water that contains dissolved ions.

The salts of sodium, chloride, and potassium are the main components of seawater and a great electrolyte.

Therefore seawater is an example of an electrolyte.

Why is carbon ideal for making different compounds?
In-s [12.5K]

Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules.

Batteries work by letting charged ions flow through an electrolyte solution.
Semmy [17]

Answer:

Batteries work by letting charged ions flow through an electrolyte solution.

A battery is a device that consists of one or more electrochemical cells that can convert stored chemical energy into electrical current. Each cell consists of a positive electrode, or anode, a negative electrode, or cathode, and electrolytes that allow ions to move between the electrodes, allowing current to flow out of the battery to carry out its function.

Explanation:

Its operation is essentially based on a reversible chemical process called reduction-oxidation, in which one of the components is oxidized and the other is reduced; that is, a process whose components are neither consumed nor lost, but merely change their oxidation state, and which in turn can return to their original state under the right circumstances.
