Answer:
Xenon is less reactive.
Explanation:
Xenon is a noble gas with 8 valence electrons whereas bromine is a halogen with 7 and is very reactive.
Answer:
165 ml
Explanation:
We are given;
Initial volume; V_a = 55 ml
Initial molarity; M_a = 3 M
Molarity of desired solution; M_b = 0.75 M
Volume of desired solution; V_b = (55 + x) ml
Where x is the volume of water to be added.
To solve for V_b, we will use the equation ;
M_a•V_a = M_b•V_b
V_b = (M_a•V_a)/M_b
V_b = (3 × 55)/0.75
V_b = 220 mL
Thus;
(55 + x) = 220
x = 220 - 55
x = 165 mL
I believe when the wave encounters a large gapless barrier, the barrier will absorb some of the wave's energy.
A wave is a periodic disturbance that propagates itself through a medium or space. When a wave encounters a barrier that is the boundary of the medium in which the wave is travelling, the wave is reflected, and the barrier may absorb some energy of the wave.
Answer:
3
Explanation:
The plates are moving away from each other
Answer:
If the object was already moving, then it will just keep moving. So, yes, the object can be moving when there is no force applied to it. Note: "force" in this discussion is to be interpreted as net force. Net force is the vector sum of all forces acting on the object.
