Metals are usually givers of electrons.
Answer:
1.95mol
Explanation:
First let us generate the equation for the reaction:
2H2 + O2 —> 2H2O
From the equation,
1mole of O2 reacted to produce 2moles of H2O.
Therefore, Xmol of O2 will react to produce 3.9 mol of H2O i.e
Xmol of O2 = 3.9/2 = 1.95mol
Answer:
It won't change.
-26F=3.33C
Explanation:
The pressure won't change since the system is closed and its volume is the exact same, the only way to change the tanks pressure is to open or pump more gas into or changing the temperature.
- To convert Fahrenheit to Celsius, you need to subtract 32 and divide by 1.8, in the next equation will substitute 26 F.
C=(F-32)\1.8
C=(26-32)\1.8
C=-3.33

This is an incomplete question, the image for the given question is attached below.
Answer : The wavelength of photon would be absorbed, 
Explanation :
From the given diagram of energy we conclude that,
Energy at ground state, A = 400 zJ
Energy of 2nd excited state, C = 1050 zJ
Now we have to calculate the energy of the photon.
Now we have to calculate the wavelength of the photon.
Formula used :
As, 
So, 
where,
E = energy of photon = 
= frequency of photon
h = Planck's constant = 
= wavelength of photon = ?
c = speed of light = 
Now put all the given values in the above formula, we get:
Therefore, the wavelength of photon would be absorbed,
C, 6. hope this message helps! <3
