In the choices above, the correct letter of the question is letter a, scintillation counter. It is because it uses a phosphor-coated surface in order to use its function in detecting radiation. Its component could produce bright flashes where it will be sufficient in detecting the radiation.
Answer & Explanation:
- The neutralization of H₂SO₄ with NaOH is occurred according to the balanced equation:
<em>H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O,</em>
It is clear that every 1.0 mol of H₂SO₄ needs 2 mol of NaOH to be neutralized completely.
<em>So, when you mix one mole of sulfuric acid with 1 mole of sodium hydroxide, there will be an excess of sulfuric acid.</em>
<em>Thus, the pH of the solution remain below 7.</em>
Answer:
it is probably acrylic or latex
Explanation:
Answer:
the number of neutrons in above isotope = A - Z = 27 - 13 = 14. Note: The molar mass of aluminium, which is average of atomic masses of all isotopes = 26.981538 g/mol, since 13Al27 is the major isotope.
