weeeeeb [17]
<span>A bond between two atoms in which the shared electron or electrons are equally likely to be found near each atom is called a non Polar Covalent Bond.

Explanation:
                   As we know atoms react in order to gain stability. Now, the bonding is done by several ways. Among these ways one is the mutual sharing of electrons between two atoms. Neither one completely accepts nor donate the electron instead they share it equally. If this sharing is purely equal then the bond formed is non polar in nature (like bonds between similar atoms), on the other hand if this sharing is not equal then one atom will get partial positive (less electron density) and other will get partial negative (more electron density) charge like in HCl.</span>

If a solution containing 126.27 g of mercury(ii) nitrate is allowed to react completely with a solution containing 17.796 g of s
Sphinxa [80]

The number of solid precipitate that will be formed is  37.08 g

calculation

write the equation for reaction

=Hg(NO3)2 +Na2SO4 = HgSO4(s) +2NaNO3(aq)

find the moles of each reactant

moles ofHg(NO3)2=126.27/324.6= 0.389 moles

moles of Na2SO4=17.796/142=0.125 moles

NaSO4 is the limiting reagent and by use of mole ratio of NaSO4:HgSO4 which is 1:1 therefore the moles of H2SO4 is also= 0.125 moles

mass HgSO4=moles x molar mass

=0.125 x296.65= 37.08g

2 Na + Cl2 --&gt; 2 NaCl<br> What is the mole ratio of sodium to sodium chloride?
Irina18 [472]

Answer: The mole ratio of sodium to sodium chloride 2:2.

Explanation:

As the given reaction equation is as follows.

2Na + Cl_{2} \rightarrow 2NaCl

Here, 2 moles of sodium reacts with 1 mole of Cl_{2} and leads to the formation of 2 moles of NaCl.

This means that 2 moles of sodium gives 2 moles of NaCl on reaction with chlorine.

Hence, the ratio of moles of sodium to sodium chloride is 2:2.

Thus, we can conclude that the mole ratio of sodium to sodium chloride 2:2.

Explain why non ionic compounds are soluble in water ?
leonid [27]
Water also dissolves non-ionic substances.This is because C2H5OH has a polar Oh and the bond that the water molecules like to hang around. Many substances do not dissolve in water and that is because they are non-polar and do not interact well with water molecules. A common example is oil and water.
