Explanation:
Objects or substances with their density greater than that of water will sink in it whiles those less than water will float on it.
From the question the object has a density of 3.4 g/mL.
Since it's density is greater than that of water the object will sink.
Hope this helps you
False. Metals such as gold/ silver even aluminium are shiny because they reflect light.
Answer:
The atom that is oxidized is Zn.
Explanation:
Reducing agents reduce other atoms or species by being oxidized themselves. Oxidation is a loss of electrons. In the equation, the Zn atom originally has an oxidation state of zero (neutral). On the right side of the equation, Zn is part of the ionic compound zinc sulfate, which is composed of the Zn(2+) cation and the SO4(2-) anion. The Zn(2+) ion is positive, which means it must have lost electrons (which have a negative charge), and was therefore oxidized from the neutral atom Zn(s).
The answer to this question is that <span>the strong base will require less HCl to bring the pH to 7 than the weak base.
The string base ionizes completely so the [OH-] will be neutralized faster. The weak base has an equilibrium that will constantly shift</span> to compensate for any [OH-] loss, meaning more HCl will be needed to titrate it to lower pH.
