Answer:
The substance formed is KCl aqueous
Explanation:
When a salt is added water to it it changes from a solid to be aqueous

Answer: = 3.11 x 10^14 s^-1
Explanation:
Use the formula E = hv
This formula uses the assumption that the unit for energy is in Joules/photon.
124 kJ = 124000J
To get 124000J/mol into a unit of J/photons, we need to divide by the number of photons in a mole, which is 6.022 x 10^23.
And thus, we need
124000/6.022 x 10^23 = 2.06 x 10^-19J/photon
We can plug it in to E = hv by
2.06 x 10^-19J = (6.63 x 10^-34 J s)(v) Isolate v by
v = (2.06 x 10^-19J)/(6.63 x 10^-34 J s)
= 3.11 x 10^14 s^-1
Answer:
Organelles that use energy from sunlight to produce food are called mitochondria.
False
Hey there! :
Mass = 156 g
Volume = 20.0 mL
Therefore:
Density = mass / volume
Density = 156 / 20.0
Density = 7.8 g/mL
