I'm not quite sure what you are saying. here is an answer to what I think you are saying. in science there are protons (positive) electrons (negative) and neutrons (neutral) I believe the answer is neutron
Answer:
M=0.380 M.
Explanation:
Hello there!
In this case, given those two solutions of aluminum bromide and zinc bromide, it is firstly necessary to compute the moles of bromide ions in each solution as shown below:
Now, we compute the total moles of bromide:
Then, the total volume in liters:
Therefore, the concentration of total bromide is:
Best regards!
I forgot this one, but I learned this in physics class. It had something to do with there being more or less electrons for how ever many photons there is in an atom.
Example: Hydrogen has 1 photon which usually means there is one electron, but when there is more electrons than photons, that is a negative ion. When there's less electrons than photons, that is a positive ion.
hope this helps
Answer:
Explanation:
The formula for the change in freezing point ΔT_f caused by an electrolyte is
1. Calculate i
Na₂SO₄(aq) ⟶ 2Na⁺(aq) + SO₄²⁻(aq)
1 mol Na₂SO₄ gives 3 mol ions.
i = 3
2. Calculate the freezing point
(a) Change in freezing point
(b) Freezing point
A semiconductor is a substance, usually a solid chemical element or compound, that can conduct electricity under some conditions but not others, making it a good medium for the control of electrical current. Silicon is a very common element -- for example, it is the main element in sand and quartz.
