Answer:
Yes, but it must be kept at that value and do not let it to decrease more.
Explanation:
Hello.
In this case, in order to substantiate whether the cabin meet the federal standards, we need to convert the 500 mmHg to atm and compare the result with 0.72 atm by knowing that 1 atm equals 760 mmHg:
Thus, since 0.66 atm is 0.06 atm away from the federal standard we can infer that it may meet the federal standard, however, it would not be recommended to let the pressure decrease more than that.
He could dry them with a towel.
In the reaction,
Cr3+(aq) + 6H2O -------> [Cr(H2O)6]3+(aq)
Cr3+ IS THE LEWIS ACID H2O is the Lewis base.
A Lewis acid is a compound or chemical that accepts a lone pair of electrons. In the above equation, Cr3+ is accepting the lone pair of electrons.
Answer:
A. The gas molecules possess kinetic energy.
Explanation:
The characteristics of the Ideal gases are given by the Kinetic Theory of gases which are as follows:-
Gases consist of particles in constant, random motion. They continue in a straight line until they collide with something—usually each other or the walls of their container.
Particles are point masses with no volume. The particles are so small compared to the space between them, that we do not consider their size in ideal gases.
No molecular forces are at work. This means that there is no attraction or repulsion between the particles.
Gas pressure is due to the molecules colliding with the walls
