Answer:
Baking soda
Explanation:
Due to its neutralizing properties, sodium bicarbonate can be used to counteract the acid corrosion of car batteries. To use baking soda, in this case, be sure to disconnect the battery terminals before cleaning. Make a paste of three parts baking soda to one part water and apply with a damp cloth to rub the corrosion of the battery terminal. After cleaning and reconnecting the terminals, clean them with petroleum jelly to prevent future corrosion.
Answer is: the partial pressure of the helium gas is 0.158 atm.
p(mixture) = 0.48 atm; total pressure.
m(H₂) = 1.0 g; mass of hydrogen gas.
n(H₂) = m(H₂) ÷ M(H₂).
n(H₂) = 1.0 g ÷ 2 g/mol.
n(H₂) = 0.5 mol; amount of hydrogen.
m(He) = 1.0 g; mass of helium.
n(He) = 1 g ÷ 4 g/mol.
n(He) = 0.25 mol; amount of helium.
χ(H₂) = 0.5 mol ÷ 0.75 mol.
χ(H₂) = 0.67; mole fraction of hydrogen.
χ(He) = 0.25 mol ÷ 0.75 mol.
χ(He) = 0.33; mole fraction of helium.
p(He) = 0.33 · 0.48 atm.
p(He) = 0.158 atm; the partial pressure of the helium gas.
