A scientific law<span> is a statement based on repeated experimental observations that describes some aspects of the universe. A </span>scientific law<span> always applies under the same conditions, and implies that there is a causal relationship involving its elements.</span>A scientific theory<span> is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported </span>theories are not "guesses" but reliable accounts of the real world.
Hey thee fella!
Based on my broad information, the systems that help human to support there-selves would actually be the ( skeletal systems).
To determine the pH of the solution. All you would have to do is use the equation:
pH = -log(H3O^+)
pH = - log(0.0007)
pH = 3.15.
Note that H+ and H3O+ are the same, it is more accurate to say H3O+ because of how the H2O molecules become after receiving the additional proton.

net ionic equation
B) SO₄²⁻ (aq) + Ba²⁺ (aq) → BaSO₄ (s)
Explanation:
We have the following chemical equation:
2 Na⁺ (aq) + SO₄²⁻ (aq) + Ba²⁺ (aq) + 2 Cl⁻ (aq) → 2 Na⁺ (aq) + 2 Cl⁻ (aq) + BaSO₄ (s)
To get the net ionic equation we remove the spectator ions and we get:
SO₄²⁻ (aq) + Ba²⁺ (aq) → BaSO₄ (s)
were:
(aq) - aqueous
(s) - solid
