Answer:- A) glucose has covalent bonds.
Explanations:- Glucose is a molecule that has carbons, oxygen and hydrogen. All these are non metals and do sharing of electrons to gain their nearest noble gas configurations and so glucose has covalent bonds.
Table salt is NaCl. Na is a metal and Cl is a non metal so the bond formed between them is ionic.
Steel alloy has Iron and carbon and so it would have ionic and metallic bonding.
Iron oxide also has a Iron(metal) and oxygen(non metal) and so it has ionic bond.
So, the only and only correct choice is A) Glucose.
<u>Answer:</u> The solubility of nitrogen gas in the sample is 
<u>Explanation:</u>
We are given:
Volume percent of nitrogen gas = 80 %
To calculate the molar solubility, we use the equation given by Henry's law, which is:
where,
= Henry's constant = 
= partial pressure of nitrogen gas = 1.0 atm
Putting values in above equation, we get:
Solubility of nitrogen gas in the sample = 
Hence, the solubility of nitrogen gas in the sample is
