Answer: i'm pretty sure it's b if i remember correctly.
Explanation:
i learned this a while ago so i'm not completely sure.
Solid's molecules have very high attraction forces, so the particles stay together and vibrate rather than any strong motion. Liquids have pretty strong attraction forces, but because they are weaker than solids, particles can move more freely, so they can slide against each other rather than vibrate. Gases have the least strong attraction forces compared to the two, so they can move everywhere, and as you know, gas is not constricted and it is everywhere, so gas is the answer.
The higher the degree of ionization, the stronger the conductivity
I will solve this question assuming the reaction equation look like this:
<span>MnO2 + 4 HCl ---> MnCl2 + Cl2 + 2 H2O.
</span>
For every one molecule of MnO2 used, there will be one molecule of Cl2 formed. If the molecular mass of MnO2 is 87g/mol and molecular mass of Cl2 is <span> 73.0 g/mol, the mass of MnO2 needed would be:
Cl mass/Cl molecular mass * MnO2 molecular mass=
25g/ (73g/mol) * (87g/mol) * 1/1= 29.8 grams</span>
Answer:
butanal
Explanation:
It's not 1-propanone because otherwise you have OH bonded to C not O and H bonded to C separately. 2-butanol means that the O and H would be bonded to a different C atom, and it's not propyl hydrogen ether because the O would be in the chain of bonded Cs.
Hope this helps :)
