Sedaia [141]
<span>1.18 x 3 = 3.55 </span>
find  ratio of F to F in each compound
.   according to law of multiple proportions  that the masses of one element which combine with a fixed mass of the second element are in a ratio of whole numbers.
now  F is  "one element" and S has  "fixed mass",
the ratio of F6 to Fx = 3:1 
<span>thats why  x= 2
there is less F in SFx
  the ratio is 3:1.
 dividing 6 by 3 and you get 2</span>

Look up and record the boiling point of acetic acid, and explain why only some of it evaporates from the reaction mixture.
REY [17]

Answer:

Heating the mixture to a temperature above the boiling point of acetic acid, but below 100°C (the boiling point of water). The vapours from the acetic acid rise, and go into a tube. They are then condensed within the tube, and run off into a separate storage area. Because water can exist as a gas at pretty much any temperature above 0°C, it will result in an impure mixture, but repeatedly doing this will get the acetic acid to the desired purity.

Type in the correct values to correctly represent the valence electron configuration of magnesium: AsB
dezoksy [38]

Magnesium (Mg) has atomic number 12 with electronic configuration :

1s^{2},2s^{2},2p^{6},3s^{2}

The valence shell of Mg is 3s which has 2 electrons as shown in above electronic configuration.

Therefore, A = 3  and B =2

What is the volume of the granite piece in cubic centimeters
Ghella [55]
Hi there!

Your correct answer will be 12.2 cm³.

This is how you get there:

1 mL = 1 cm³

With this one conversion factor, you can extrapolate the final answer. When you add the granite to the water, which is filled to 25.0 mL, the water level then moves to 37.2 mL. If you subtract the before volume from the volume after, you will get an answer of 12.2 mL. Then use the conversion factor and, voila! 12.2 cm³

I hope this helps!
