b. F₂ have a polar covalent bond
Explanation:
The type of bond depends on the difference of the electronegativity of the two elements.
if the electronegativity difference is under 0.4 the bond is non-polar covalent
if the electronegativity difference is between 0.4 and 1.7 the bond is polar covalent
if the electronegativity difference is greater 1.7 the bond is ionic
a. HCl
electronegativity of Cl - electronegativity of H = 3 - 2.2 = 0.8, so the bond is polar covalent
b. F₂
electronegativity of F - electronegativity of F = 4 - 4 = 0 , so the bond is non-polar covalent
c. HF
electronegativity of F - electronegativity of H = 4 - 2.2 = 1.8, in this case because non-metals are involved in the bond we consider this to be a polar covalent bond.
d. ClF
electronegativity of F - electronegativity of Cl = 4 - 3 = 1, so the bond is polar covalent

Hey there!:
moles of NaOH = 10.1 / 40 = 0.2525
heat = ΔH x moles
= 44.4 x 0.2525
= 11.21 kJ
total mass = 10.1 + 250 = 260.1 g
Q = m Cp dT
11211 = 260.1 x 4.18 x dT
dT = 10.3
T2 = 10.3 + 23 = 33.3 °C
temperature = 33.3 ºC°
Hope this helps!
Answer:
Image result for What is the major cause of erosion and weathering that affects coastline features?
Coastal erosion, which is the wearing away of coastal land or beaches, is mainly caused by the impact of waves along the shoreline. This is accentuated during storms when waves are large and crash on shore with a lot of energy. ... As the sand and rocks crash into the coast, they grind away land and rock.

Answer:
Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells. The membrane also maintains the cell potential.
Explanation:
(see above)
The sulfur and nitrogen compounds in smog combine with water to form Acid Rain. Acid rain is harmful to the environment and infrastructure because of its aidic components.
