Answer:
tetrahedral
Explanation:
it sounds like a tetrahedral shape, which is when there are four bonds and no lone pairs around the central atom in the molecule.
Answer:
in H2So4 splits in 2 H+ and a
so42 -particle=3particle per mole.So2
moles H2So4 will result in 3*2=6moles
of molecules.
The answer is d because in both sides there are 1 magnesiums 1 oxygens 2 lithiums and 2 chlorines
Answer:
a. True
Explanation:
Methyl red is an indicator widely used in quality control of oxides as Zinc oxide in the titration with sulfuric acid.
As is used in titrations of acid-base reactions the indicator change in colour. Is red when the pH < 4.4 (Acidic Solutions) and is yellow when pH > 6.2 (Neutral-Basic solutions).
A change in colour means the structure of the indicator is changing with pH. Thus, the answer is:
<h3>a. True
