Answer:
0.22 atm
Explanation:
The total pressure is the sum of the partial pressures.
P = P₁ + P₂ + P₃
1.25 atm = 0.68 atm + 0.35 atm + P
P = 0.22 atm
<span>In the electron cloud model, the denser areas represent that there is a great probability that a good number of electrons are ganged up or crowded in that area. The electrons affect the density of some parts of the electron cloud when they condense in those locations.</span>
Not quite sure what you mean by matter ? Yes air is matter and yes it does matter ! Air is various gasses that support life and other things ! We use air for so many things, it's very important c:
Absolutely false. If it all have the same average kinetic energy, the substance will not change in state. Hence, it is absolutely false. Go to Google and search for heating curve. When you analyse the curve, the line which is horizontally straight is where the average kinetic energy remains constant. The other lines represent the increase in kinetic energy. So as heat is continued supplying, the substance at some point will increase kinetic energy.
The answer is A. Melting snow because it is a physical change because you can then trun around and make it snow again
Physical change you can turn it back to the original
Chemical you can not
