Explanation:
Li will have + charge and Cl with - charge.. Positive and negative attract each other forming ionic bond
I don’t really understand but the symbols of these elements on the periodic table are
MgAgN
and 9.8 m/s^2 is the acceleration of gravity, commonly abbreviated as ‘g’
If you take out the ‘g’s from the periodic table equation(bc the question says 9.8m/s^2 is silent) it spells MAN
So the question could be “Will you be my man?”
Answer:
Explanation:
The Ideal Gas Law states that PV=nRT.
Rearrange that into P/n=RT/V.
In this case, the cylinder is rigid so the volume, V, does not change.
Temperature does not change either.
Out of 450 grams of gas, 150 grams leak out. So only 450-150 = 300 grams is left.
n is number of moles which is dependent on mass:
n1/n2 = 450/300 = 3/2
P1/n1 = RT/V = P2/n2
P2 = P1/n1*n2
= 7.2/3*2
= 4.8 atmosphere
