Answer:
Increasing the concentration of a substance will increase the rate of reaction because in a conc substance the particles are more clustered together and this causes more effective collisions thus increasing the rate of reaction and when the substance isn't concentrated the particles aren't really close and this reduces the rate of reaction because alot of collisions can't be made compared to that of the concentrated substance
Answer:
Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one equalizing the concentrations on each side of the membrane.
Explanation:
We know that
Speed of light = wavelength X frequency
Energy of light = h X frequency
Where
h = planck's constant = 6.626 x 10–34 j·s
frequency = speed of light / wavelength = 2.998 x 10^8 m/s / 656.3 X 10^-9
frequency = 4.57 X 10^14 / s
Energy = 6.626 x 10–34 j·s X 4.57 X 10^14 / s = 3.028 X 10^-19 Joules

Answer: magnesium sulfide</h2>
<h3>
Explanation:</h3>
MgS → Mg²⁺ + S²⁻
S²⁻ is known as the sulfide ion. That makes MgS Magnesium Sulfide.
For consideration:
magnesium sulfide MgS
magnesium sulfite MgSO₃
magnesium sulfate MgSO₄
magnesium sulfur Mg & S
