Answer:
1 g/cm3
Explanation:
The formula for density is mass/volume
The mass is 100 g and the volume is 100 cm3
100 g/100 cm3=1 g/cm3
<u>Answer:</u> The pH of the cleaning compound is 10.44
<u>Explanation:</u>
pH is defined as the negative logarithm of hydrogen or hydronium ion concentration that are present in a solution.
The equation representing pH of the solution follows:
We are given:
Putting values in above equation, we get:
Hence, the pH of the cleaning compound is 10.44
To perform nuclear fusion reactions, the following requirements must be present: Get a very high temperature to separate the electron from the nucleus, approaching this another beating electrostatic repulsion forces. The gaseous mass consisting in the electrons and free atoms is called highly ionised plasma.
So, it’s chemical plasma.
Hope this helps:)
At s.t.p, the volume of a gas =22.4dm³
Talking the problem,
At 1atm, 273K the volume =7 moles *22.4dm³/mol
At 323K, 2.90atm, volume =?
The combined gas equation
P1v1/T1=P2v2/T2
P1=1atm
P2=2.9atm
T1=273K
T2=323K
V1=156.8dm³
Therefore,
1*156.8dm³/273=2.9atm*V2/323
V2=(156.8dm³*323K)/(273K*2.9atm)
= 64dm³
