Explanation:
Hydrochloric acid is a strong acid, that is, an acid that dissociates completely, according to the following reaction.
HCl(aq) → H⁺(aq) + Cl⁻(aq)
Then, the concentration of H⁺ will be equal to the initial concentration of the acid, i.e., 0.10 M.
We can calculate the pH using the following expression.
pH = -log [H⁺] = -log 0.10 = 1.0
Answer:
Uranium-238 undergoes alpha decay to form Thorium-234 as daughter product.

Answer:
Kapilari lebih kecil dan paling banyak saluran darah, mereka membentuk sambungan antara vesel yang membawa darah dari pendengaran (arteri) dan vesel yang mengembalikan darah ke jantung (urat)
Fungsi utama kapilari ialah pertukaran bahan antara sel darah dan tisu.
Veins membawa darah ke arah jantung; selepas ia melewati kapilari dan masuk melalui urat terkecil (venules).
Arteri membawa darah dari jantung; arteri sistemik mengangkut darah oksigen dari ventrikel kiri ke tisu badan.

Why blood capillary walls differ from veins and arteries
Capillaries are smaller and the most numerous of the blood vessels, they form the connection between the vessels that carry blood away from the hear (arteries) and the vessels that return the blood to the heart (veins)
The primary function of the capillaries is the exchange of materials between the blood and tissue cells.
Veins carries the blood towards the heart; after it passes through the capillaries and enters through the smallest veins (venules).
Arteries carries blood away from the heart; systemic arteries transport oxygenated blood from the left ventricle to the body tissues.
