Answer:
I think it's lead (pb). Hope this helps.
Answer:
Simply identify what elements are in a compound
Explanation:
For example in NaCl we have sodium (Na) and Chlorine (Cl)
In order to do this you would need to recognise the symbols for a certain element: O for oxygen; N for nitrogen; H for hydrogen etc.
Yeah, it's diffferen than a solution.
What would it be if it were all the same element?
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:
It does not contain free mobile ions
Explanation:
Solid sodium chloride does not conduct electricity because it does not contain free mobile ions.
- Although sodium chloride is an ionic compound, in solid state, there is absence of free mobile ions.
- In aqueous solutions or in molten form, ionic compounds can conduct an electric current using free mobile ions as carriers.
- Therefore, they are electrolytes.
In solid state ions are arranged into crystal lattice and will not conduct a current of electricity.
