4 0

Answer:

D, E, A, B, C

Explanation:

The weakest base would be Cl- because HCl is a stronger acid than that of H3O+ from which the water is formed.

Also, for NH3 is a stronger acid than +NH4. Reason is that oxygen is more electronegative than nitrogen and thus NH3 is a stronger acid than NH4+.

The stronger, the acid, the weaker its conjugate base. Thus, NH3 is a weaker base than NH4.

NH2- has the highest basicity because nitrogen is less of an electronegative element than is oxygen. Therefore, it will not want a negative charge.

Hence, the final order in terms of increasing basicity is;

Cl-, H20, NH3, NH4, NH2-

1. Use your knowledge of valence electrons and how they affect bonds to figure out how carbon (Group 14) and oxygen (Group 16) w
erik [133]

From the fact that oxygen is in group 16 and carbon is in group 14, the structure of CO2 must be O=C=O. In methane, there is no bond between any of the hydrogen atoms. The structure of H2O2 is H–O–O–H.

Carbon is in group 14 hence it has four valence electrons and oxygen is in group 16 hence it has six valence electrons. This implies that each oxygen atom will share four electrons with carbon in a covalent bond to form the structure O=C=O.

In CH4, we know that carbon is tetravalent so it forms for bonds. Therefore, there is no bond between hydrogen atoms so it bonds with each hydrogen atom; hydrogen only forms one bond.

In H2O2, there is the peroxide ion that has the structure O-O. Hence, the correct structure of H2O2 is H–O–O–H.

What volume of 0.100 M HCl will react completely with 50.00 mL of 0.200 M NaOH?
skelet666 [1.2K]
Equation of reaction
Hcl+NaoH-->Nacl+H2O
1:1
Using the formula CaVa/CbVb=na/nb
Ca(Concentation of acid)= 0.100M
Cb(Concentration of base)=0.200M
Va=?
VB=50.00ml
na=1
nb=1
from the formula
Va= CbVbna/Canb
Va= 0.2*50*1/0.1*1
=10/0.1=100ml
Therefore volume of acid = 100ml
