Answer:

SO has about 0.52 moles, while NO has about 0.83 moles

Explanation:

To calculate the number of moles of a certain molecule, you first need to figure out that molecule's molar mass. For SO, the molar mass is the mass of sulfur combined with the mass of oxygen. 16 + 32=48. For NO, you do a similar thing but with nitrogen. 16+14=30. From here, you can simply divide. 25 grams divided by SO's molar mass of 48 yields about 0.52 moles, while for NO there is about 0.83 moles. Hope this helps!

Why are we pulled to the center of the Earth and not into the much larger sun?

katrin [286]

Answer:

The sun's gravity pulls on the earth, and the earth pulls back on the sun at the same time. This is why the center of the solar system is not the center of the sun. As one gravitational body gets bigger than the other, it circles closer to the center of the system (shown in red).

What volume of 0.140 HCl is needed to neutralize 2.58 of Mg(OH)2<br> ? ...?

elena-s [515]

To make a first step you have to know the balanced form for neutralization formula: $Mg(OH)2(aq)+2HCl(aq)--\ \textgreater \ 2H2O+Mg(aq)+Cl(aq)
$
According to this, you can <span>calculate what you are being asked :</span> $0.0442molMg(OH)2(x)(2molHCl)/(1molMg(OH)2)=0.0885molHCl$
Then we have : $0.140MHCl=0.140(mol/L)HCl$
Hope everything is clear, here is the exact answer you need : $V=(0.0885molHCl)/(0.140(mol/L)HCl)=0.632LHCl

In what beaker does the sugar dissolve the fastest? ( particle size, temp. of water, condition(stir/no stir), etc).

Vsevolod [243]

Temperature. In case you have ever baked, you can relate to this. For example, when you make caramel, you simply put the caramel on a boiling hot pan and sit back and watch it. It always goes fastest this way.
