Answer:
pH = 4.44
Explanation:
You take the negative logarithm of the hydronium ion concentration.
pH = -log[H₃O⁺] = -log(3.6 × 10⁻⁵) = 4.44

Mars is the inner planet with the most moons. Earth has one moon, Mars has two and Mercury and Venus have none.
Solution :
From the balanced chemical equation, we can say that 1 moles of KBr will produce 1 moles of KCl .
Moles of KBr in 102 g of potassium bromide.
n = 102/119.002
n = 0.86 mole.
So, number of miles of KCl produced are also 0.86 mole.
Mass of KCl produced :
Hence, this is the required solution.
Metalloids are all solid at room temperature<span>. Some metalloids, such as silicon and germanium, can act as </span>electrical<span> conductors under the right conditions, thus they are called semiconductors. Silicon, for example, appears lustrous but is not malleable or </span>ductile<span> (it is brittle - a characteristic of some nonmetals).
