A, Homogenous | b, heterogenous | c, homogenous
Answer:
Neptunium, Protactinium, plutonium and more
Explanation:
[ H₃O⁺] = 10 ^- pH
[ H₃O⁺] = 10 ^ (- 5.75 )
[H₃O⁺] = 1.778x10⁻⁶ M
Kw = [ H₃O⁺] x [ OH⁻]
1x10⁻¹⁴ = 1.778x10⁻⁶ x [OH⁻]
[OH⁻] = 1x10⁻¹⁴ / 1.778x10⁻⁶
[OH⁻] = 5.62x10⁻⁹ M

Answer:
The answer is
<h2>55.56 cm³</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula

From the question
mass of aluminum = 150 g
density = 2.7 g/cm³
The volume is

We have the final answer as
<h3>55.56 cm³</h3>
Hope this helps you
