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
Becuse the earth rotates the opisate way on the other side of the equator forgive me if im wrong.
Answer:
[H⁺] = 1.0 x 10⁻¹² M.
Explanation:
<em>∵ [H⁺][OH⁻] = 10⁻¹⁴.
</em>
[OH⁻] = 1 x 10⁻² mol/L.
∴ [H⁺] = 10⁻¹⁴/[OH⁻] = (10⁻¹⁴)/(1 x 10⁻² mol/L) = 1.0 x 10⁻¹² M.
∵ pH = - log[H⁺] = - log(1.0 x 10⁻¹² M) = 12.0.
∴ The solution is basic, since pH id higher than 7 and also the [OH⁻] > [H⁺].

Explanation:
Answer:
C) They all have single covalent bonds.
Explanation:
The given hydrocarbons Butane,Ethane,Methane,Propane belongs to alkane group.
In alkane group consists of hydrogen and carbon in which carbon_carbon bonds are single and carbon_hydrogen bond is also single.
The elements of this group makes bond by sharing of electrons that means they form single covalent bond.
Butane have 4 , Ethane has 2, Methane has 1, and Propane has 3 carbon atoms.
Since they have different number of carbon atoms so their structural formula also differs.
