What is aqueous sodium sulfide reacts with aqueous copper(ii) nitrate to form aqueous sodium nitrate and solid copper(ii) sulfide?

In a chemical reaction one or more reactants combine or react to form one or more product(s) with different chemical and physical properties.

When aqueous sodium sulfide reacts with aqueous copper(II) nitrate results in the formation of aqueous sodium nitrate and solid copper(ll) sulfide.

First, identify the chemical symbols for the elements in the compounds.

Sodium sulphide =

Copper(II) nitrate =

Sodium nitrate =

Copper(II) sulfide =

The chemical reaction is given as:

Now, balance the chemical equation:

For balance the equation, multiply by 2.

Thus,

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.
