The factor that affects how easily an electron can be removed from an atom is D. the structure of the atom.
Hope this helped! :)
Faster than the hurricane at least 250 feet
Answer:
Reaction will move rightwards.
Explanation:
Hello there!
In this case, according to the proposed question, it turns out possible for us to figure out the effect of the addition of silver nitrate, by using the following representative equation for the formation of the silver chloride precipitate:
Now, due to the addition of silver nitrate, we will be actually adding silver ions to the solution, which means that, in terms of the Le Ch atelier's principle, the reaction will shift to the right towards the formation of more silver chloride precipitate.
Best regards!
Epsom salt is MgSO4.
We assume x water of hydration in the crystalline form.
Molecular mass of MgSO4 = 24+32+4*16=120
Molecular mass of MgSO4.xH2O = 120+18x
By proportion,
2.000/0.977 = (120+18x)/120
Cross multiply
0.977(120+18x) = 120*2.000
from which we solve for x
17.586x+117.24 = 240
x=122.78/17.586
=6.980
Answer: there are 7 water of hydration in Epsom salt, according to the experiment.
Note: more accurate (proper) results may be obtained by using exact values (3-4 significant figures) in the molecular masses. However, since water of hydration is the nearest integer, using approximate values (to at least two significant figures) suffice.
