I found a similar question online which will help me answer your incomplete question. To make it easier, show all the elements of the compound given. It is shown in the second picture attached.
a.) The formula for unsaturation number is shown in the 3rd picture attached. Following this,
n = 8
m = 2(8) + 2 + 0 + 0 - 0 = 18
Thus,
x = Unsaturation number = (18 - 8)/2 = 5
<em>The unsaturation number is 5.</em>b.) The molar mass of C is 12.01 g/mol; H is 1 g/mol; O is 16 g/mol. So, the molecular weight is:
Molecular weight = 12.01(8) + 8(1) + 2(16) = 136.08 g/mol
<em>The molecular weight of the ester is 136.08 g/mol.</em>
A mixture can be called as a solution when the mixture is homogeneous
Iron filings can be attracted by the magnet whereas salt can not. So the mixture can be separated by a magnet
Answer is: <span>the solubility of the new compound.
</span>Precipitates are insoluble ionic solid products, formed when certain cations and anions combine. Factors need for precipation reactions are: <span>temperature, buffers, solution concentration.</span>
Solubility rules determines if precipate will occur or not.
Answer:
Oxygen
Explanation:
Oxygen is more reactive because it has small atomic size which has high tendency to attract more electrons.
