For this, you need to know 1) the mass of the hydrate and 2) the mass of the anhydrous salt. Once you have both of these, you will subtract 1) from 2) to find the mass of the water lost.
From the problem, you know that 1) = 2.000 g.
Now you need to find 2). You know that your crucible+anhydrous salt is 5.022 g. To find just the anhydrous salt, subtract the mass of the crucible (3.715 g).
1) = 5.022 g - 3.715 g = 1.307 g
Now you can complete our original task.
Mass H2O = 2) - 1) = 2.000 g - 1.307 g = 0.693 g.
Answer:
C: the repulsion of electrons and electrons.
Explanation:
According to the VSEPR theory, molecular shapes adjust so that the electrons can be as far apart as possible due to electrons repelling each other, which would mean the only possible answer is C.
Sin 32 = height/3.3 m
height = sin 32 (3.3 m)
height = 1.75 m
Answer:
B im so sorry if its wrong im sure it right
Explanation:
see it has the lowest specific heat so it wouldnt cool because of the bionestint particles
