The solvent for the mixture is water
<em><u>Explanation</u></em>
- <em><u> </u></em>Solvent is substance that dissolves the solute in a solution.
- solvent must be present at a higher percentage as compared to solute.
- water is the solvent in a homogeneous mixture that consists 12% ethanol, 28% methanol and 60% water, since it contain more % than ethanol and methanol.
Explanation:
The condensed formula of a molecule is the formula where the symbols of atoms are listed in order as they appear in the molecule's structure with bond dashes omitted or limited.
The structural formular however, showed how the atoms are connected.
The condensed formular is given as; HOCH2COCH2OH
The condensed formular was gotten by writting out the elemnts in the order that they appear in.
The stuctural formular is shown in the attachement.
Answer:
0.31g KCl
Explanation:
Before we can start, we have to wonder, how many moles of KCl is formed from KClO3? To figure that out we have to make a balanced equation.
KClO3 -> KCl + O2
How do I know it makes O2? Looking back at the problem they're asking for KCl, which has less ions than KClO3 so it must have been broken down. So we can say it's a decomposition type of reaction. We can't just slap on O3, we know oxygen is one of our diatomic elements that usually exists as O2 so we'll put it down as O2 and balance our equation.
2KClO3 -> 2KCl + 3O2
Now that we know every 2 moles of KClO3 makes 2 moles of KCl, this is our mole to mole ratio. Knowing the ratio between the 2 compounds in our problem is the stepping stone from converting from grams KClO3 -> moles KClO3 -> moles KCl -> grams KCl.
1. Let's first convert grams KClO3 -> moles KClO3
2. Convert moles KClO3 -> moles of KCl using our mole to mole ratio
3. Convert moles KCl -> grams KCl
Correct answer is C
Na2O + H2O ----> 2 NaOH

Earthquakes generate three types of seismic waves<span>: P (primary) </span>waves<span>, S (secondary) </span>waves<span> and surface </span>waves<span>, which arrive at </span>seismic<span> recording stations one after another. Both P and S </span>waves<span>penetrate the interior of the Earth while surface </span>waves<span> do not. Due to this, P and S </span>waves<span> are known as "body </span>waves<span>".
hope that helped</span>
