Calculate the volume in mL of a 1.420 M NaOH solution required to titrate the following
solutions:
a) 25.00 mL of a 2.430 M HCl solution
b) 25.00 mL of a 4.500 M H2SO4 solution
C) 25.00 mL of a 1.500 M H3PO4

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.

c. is the answer
