Answer:
Grinidng chalk into a fine powder
Explanation:
Answer:
Option B. Sodium
Explanation:
In the formation of NaCl, sodium loses and electron while chlorine receives the electron as illustrated below:
Na —> Na+ + e- ....... (1)
Cl + e- —> Cl- ......... (2)
Now, combining equation 1 and 2 we have:
Na + Cl + e- —> Na+ + Cl- + e-
Cancelling the electron from both side, we obtained:
Na + Cl —> Na+Cl-
From the above illustration, we see clearly that sodium loses electron
Answer:
Na+
Explanation:
The equation would be:
HCl (aq) + NaOH (aq) --> HOH (l) + NaCl (aq)
The equation is already balanced and the NaCl will disassociate in Na+ and Cl- and HCl will disassociate into H+ and Cl- and NaOH will disassociate into Na+ and OH-. Na+ is on both sides of the equation and stays the same, so Na+ will be the spectator ion.
Answer: No
Explanation: It's not balanced because four oxygen atoms in H2SO4, whereas there are 5 oxygen atoms in the reactants side. Also, there's more hydrogen atoms on the reactants side.
I hope this helps!
Answer: Weak acids are poor conductors of electricity.
Explanation:
Weak acids are defined as the acids which dissociate weakly or partially when dissolved in water (polar solvent).
For example, 
Due to less dissociation there will be less number of ions present in a solution of weak acid. As a result, a weak acid will be poor conductor of electricity.
As electricity is the flow of ions.
Thus, we can conclude that weak acids are poor conductors of electricity.
