We know that molarity = mol/L, so:
1.5 M = x mol/0.345 L
1.5 M * 0.345 L = x mol => 0.5175 mol
0.5175 mol/0.250 L = 2.07 M
Your new molarity of the solution will be 2.07 M.
is the Calcium
because the calcium in group two which group two has 2 electron and also calcium and Potassium 4s sub level group potassium has 1 electron. :)
Answer:
A <u><em>reducing agent </em></u>is an element or compound that loses (or "donates") an electron to an electron recipient (oxidizing agent) in a redox chemical reaction.
Explanation:
Redox reaction is defined as the reaction in which oxidation and reduction reaction occur simultaneously.
Oxidation reaction is defined as the chemical reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.
Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.
Electrons are transferred from one atom to another in this type of reaction.
Reducing agent is defined as those substance which reduces other chemical compound and oxidizes itself by donating electrons.
Oxidizing agent is defined as those substance which oxidizes other chemical compound and reduces itself by accepting electrons.
If the magnetic lines of force intersected each other, then that would violate the laws of physics.
If the lines intersected, then at the point of
intersections there would be two directions of magnetic field force, and this cannot defy the laws of physics, so therefore it does not happen.
A good example of this would be if you had a
compass and you tried to use it to view the field direction. If you had two lines of force
intersecting, then the compass would have to
point in both directions, and that can't happen both theoretically and through observation.
An event like that would generate a monopole, which is an impossible, theoretical magnetic event.
Answer:
Yah, it's true.
because protons are represented as helium (²4He) which are positive.
electrons are represented as 0-1e which is negative
