it’s how’s how dens the ball is
The theory of infinite universe and the theory of vacuum as a substance. First was disproved by the discovery of the big bang and the later by some experiments with light which have shown that vacuum is not a substance but empty space.

Answer:
Energy levels 4-7
Explanation:
The energy levels in an atom are shown by the principal quantum number (n). Typically, the d orbitals begins to occur from the third energy level through the seventh energy level.
Most second and third row d-block elements are found between energy level n=4 and energy level n= 7 in the periodic table. Hence the answer
Answer:
The answer to your question is 242 ml
Explanation:
Data
HI 0.211 M Volume = x
KMnO₄ 0.354 M Volume = 24 ml
Balanced Chemical reaction
12HI + 2KMnO₄ + 2H₂SO₄ → 6I₂ + Mn₂SO₄ + K₂SO₄ + 8H₂O
Process
1.- Calculate the moles of KMnO₄ 0.354 M in 24 ml
Molarity = moles / volume (L)
moles = Molarity x volume (L)
moles = 0.354 x 0.024
moles = 0.0085
2.- From the balanced chemical reaction we know that HI and KMnO₄ react in the proportion 12 to 2. Then,
12 moles of HI --------------- 2 moles of KMnO₄
x --------------- 0.0085 moles of KMnO₄
x = (0.0085 x 12)/2
x = 0.051 moles of HI
3.- Calculate the milliliters of HI 0.211 M
Molarity = moles/volume
Volume = moles/molarity
Volume = 0.051/0.211
Volume = 0.242 L or Volume = 242 ml
