Answer:
The mass of formed sodium sulphate solution is 14.2 g.
Explanation:
From the given,
Mass of copper sulphate = 15.9 g
Mass of sodium sulphide = 7.8 g
Total mass of reactant = Mass of copper sulphate + Mass of sodium sulphide
= 15.9 + 7.8g = 23.7g
Mass of copper sulphide formed = 9.5 g
Mass of sodium sulphate = Total mass - Mass of copper sulphide
= 23.7 g - 9.5 g = 14.2 g
Therefore, The mass of formed sodium sulphate solution is 14.2 g.
If you're including protons that are bound as part of an atomic nucleus, then, yes, under certain conditions.
The half life, this is how long it takes for half of the atoms to decay
Answer:
Square planar.
Explanation:
Hello,
In this case, it can be demonstrated that the central atom Xenon in XeF₄ has a sp³d² hybridization which means that its geometry is likely to be octahedral. Nevertheless Applying by applying the valence shell electron pair repulsion (VSEPR) model to in order to minimize the repulsion among lone pairs, bond pairs and lone pair-bond pairs, we we realize repulsion is actually minimized when lone pairs are anti to one another and the fluorine atoms are in equatorial position, for that reason, the corrected and properly exhibited geometry or molecular arrangement of the compound turns out square planar. You can verify it on the attached picture.

Number of millimoles of NaOH consumed in present titration =<span>33.23 X 0.09892
= 3.287
Thus, number of millimoles of vinegar present in sample = 3.287
Now, Molarity of vinegar solution = </span>

<span> = </span>

<span> = 0.1222 mol/dm3
Molar concentration of vinegar present in sample solution is 0.1222 M </span>
