Write a balanced chemical equation based on the following description:
kupik [55]

The balanced chemical equation for the reaction is

<h3>6Cs(s) + 2CsNO₂(s) —> 4Cs₂O(s) +  N₂(g) </h3>

From the question given above, we were told that:

solid cesium reacts with solid cesium nitrite to form solid cesium oxide and nitrogen gas.

The equation for the reaction can be written as follow:

Caesium => Cs

Caesium nitrite => CsNO₂

cesium oxide => Cs₂O

nitrogen gas => N₂

Caesium + Caesium nitrite —> Caesium oxide + Nitrogen gas

<h3>Cs + CsNO₂ —> Cs₂O +  N₂</h3>

The above equation can be balance as follow:

Cs + CsNO₂ —> Cs₂O +  N₂

There are 2 atoms of N on the right side and 1 atom on the left side. It can be balance by writing 2 before CsNO₂ as shown below:

Cs + 2CsNO₂ —> Cs₂O +  N₂

There are 2 atoms of Cs on the right side and a total 3 atoms on the left side. It can be balance by writing 6 before Cs and 4 before Cs₂O as shown below:

6Cs(s) + 2CsNO₂(s) —> 4Cs₂O(s) +  N₂(g)

Now the equation is balanced

If a gas’s [kelvin] temperature doubles and it’s volume then remains the same, then what happens to it’s pressure?
Tamiku [17]

Answer:

The final pressure will double i.e it will be twice the initial pressure

Explanation:

T1 = T

T2 = 2T ( twice the original T)

P1 = P

P2 =?

Since the volume is constant,

P1/ T1 = P2 /T2

P/ T = P2 / 2T

Cross multiply

T x P2 = 2T x P

Divide both side by T

P2 = (2T x P) / T

P2 = 2P

Therefore, the final pressure will double i.e it will be twice the initial pressure
