A
A is incorrect. It depends very much on which gas it is. O2 has vastly different properties than F2
B
Yes it can. The molar mass of oxygen is 2 * 16 = 32
The molar mass of F2 = 2*9 = 18
C
The molar mass is independent of temperature So C is false
D
is True
B and D are both true.
This is due to water pressure
<span>(symbol K)</span><span> Energy that an object possesses because it is in motion. It is the energy given to an object to set it in motion; it depends on the mass (</span>m) of the object and its velocity (v<span>), according to the equation K = 1/2 </span>mv2<span>. On impact, it is converted into other forms of energy such as heat, sound and light.</span>
Low pH means a the solution is acidic, which means the answer is C. it has a high hydrogen-ion concentration
