What best describes the result is a mixture
Answer:
The youngest rock layers are at the top and the oldest are at the bottom, which is described by the law of superposition.
Explanation:
Answer:
Hydrogen ion concentration is more conveniently expressed as pH, which is the logarithm of the reciprocal of the hydrogen ion concentration in gram moles per liter.
Explanation:
Thus, in a neutral solution the hydrogen ion (H+) and the hydroxyl ion (OH−) concentrations are equal, and each is equal to 10−7. A pH of 7 is neutral.
Answer:
PbSO₃(s)⟶PbO(s)+SO₂(g)
Explanation:
In order for an equation to be balanced, both <em>the charges</em> and <em>the masses </em>need to be the same in both sides of the equation.
In the case of the reaction PbSO₃(s)⟶PbO(s) +SO₂(g), there are no charges in either side, so it is already electronically balanced.
Regarding masses, let's see each element one by one:
Pb ⇒ There's 1 Pb in both sides already.
S ⇒ There's 1 S in both sides already.
O ⇒ There're 3 O in both sides already.
So the equation is balanced as is.
