<span>The best property for ionic bonds is its conductivity of electricity when molten. An experiment that can be recalled on this is the NaCl in water that is used to light up a bulb. Ionic compounds are highly soluble in water when dissociates. They also have high boiling points because of the ions integrated. </span>
The reaction for magnesium iodide when put into water is as below
MgI2(s) → Mg^2+(aq) + 2I^-(aq)
when magnesium iodide but into water it dissociate/ ionize completely into Mg^2+ and 2l^- ions. Magnesium iodide dissociate/ionize completely because magnesium iodide is a strong electrolyte which dissociate/ ionize completely into their ions when it is put into water .
Answer :
(a) The energy is,
(b) The wavelength (in nm) is,
Explanation :
The general formula for the wavelength of spectral line emitted by a hydrogen atom, when it makes a transition from shell to shell is,
where,
= wavelength
Rydberg's Constant =
In this, and
conversion used :
Now we have to calculate the energy.
Formula used :
= Wavelength =
E = energy = ?
c = speed of light =
h = Planck's constant =
Now put all the given values in the above formula, we get:
Therefore, the energy is
1 is A 2 is B
Primary Consumers are Herbivores (vegetarians) and Secondary Consumers are Carnivores (meat eaters)
Answer:
Mario uses a hot plate to heat a beaker of 50mL of water. He used a thermometer to measure the
temperature of the water. The water in the beaker began to boil when it reached the temperature of
100'C. If Mario completes the same experiment with 25mL of water, what would happen to the boiling
point?
a) The water will not reach a boil.
b) The boiling point of water will increase.
c) The boiling point of water will decrease.
d) The boiling point of water will stay the same.
