Answer:
D
Explanation:
Both images have 4 protons (positive particles) and 4 electrons (negative particles) so in total they don't have a charge. (<em>you don't have to worry about neutrons in this case, because they don't have a charge.)</em>
An ion has a charge so neither image is an ion
Electrolytic conductivity is measure of ability of solution to conduct electricity. It is also as specific conductance. Electrolytic conductivity is different as compared to electrical conductivity. Electrolytic conductivity increase with temperature, while electrical conductivity decreases with increasing temperature. Further, electrolytic conductivity occurs because of presence of ions in solutions, while electrical conductivity occurs due to presence of valence electrons.
In current context, number of ions present in solutions depends on dissociation constant values. For molecules, which donot under dissociation in solvent, no electrolytic conductivity will be observed. Generally, ionic compounds undergo complete dissociation in solution, hence they will display maximum conductance. In case of acids, conductivity values will vary depends upon dissociation constant values. Weak acid are characterized by lower dissociation constant values, hence they have lower conductivity as compared to strong acids. <span />
Answer:
B. It will become more green and brown
Explanation:
Le Chateliers principle states that when a constraint such as change in concentration, volume, pressure or temperature is imposed on a reaction system at the equilibrium, the equilibrium position will shift in such a way as to annul the constraint. Let us see how this applies to the equation under consideration.
If the system is at equilibrium and more ICl3 is added to the system, the equilibrium will shift towards the left hand side (more reactants are formed). This implies that the colour of the system will become more green and brown since there are more reactants now in the system.
Answer:
1 mole of lithium is 7 grams. we know this from it's relative molecular mass.
if 1 mole is 7 grams then x moles is 0.56 grams
we can equate them by saying (1/x)=(7/0.56)
after cross multiplying, we get 7x=0.56, x will be equals to 0.56/7
x=0.08 grams
Calcium Chloride's chemical formula is CaCl2.
