I think the answer would be trenches but I’m sorry if I’m wrong
Answer:
H-Cl is a polar bond.
Explanation:
a polar bond is when 2 different elements share the same electrons except one is negative charge and the other is positive.
Cl is a negative charge while H gives off a positive charge, these are also the only one that have 2 different elements.
D. Metals
Elements that are shiny, solid, conducts electricity, has atomic mass of 108 is metal.
Use PV =nRT. Rearrange it to n = PV/RT.
P = 202.6 kPa
V = 4.0L
R = 8.314 kPa*L/mol*K
T = 127 °C + 273 = 400 K
Plug it in and solve. I got 0.24 moles of H2.
