Answer: covalent bond
Explanation: Yeah that's the answer
7.66g of ethyl butyrate is produced.
The reaction is
CH₃CH₂CH₂COOH + CH₃CH₂OH ----> CH₃CH₂CH₂COOCH₂CH₃
- The molar mass of butanoic acid is 88.11g/mol
- We have 7.45g of butanoic acid
- The moles of butanoic acid we have is 7.45/88.11 = 0.0845 mol
- If the yield is 100%, 1 mole of butanoic acid gives 1 mole of ethyl butyrate
- But the reaction yield is 78%
- 1 mole of butanoic acid gives 0.78 mole of ethyl butyrate
From 0.0845 mol of butanoic acid we get 0.78 x 0.0845 = 0.66 mol of ethyl butyrate.
The molar mass of ethyl butyrate is 116.16g/mol
So 0.66 x 116.16 = 7.66g
7.66g of ethyl butyrate is produced.

Answer:
E) Silver, mass = 420 g, d = 10.5 g/cm.
Explanation:
Hello,
In this case, since the density is defined by:
Given the mass and density, we compute the volume via:
Thus, for each vase we have:
A) 
B) 
C) 
D) 
E) 
In such a way, the largest volume corresponds to E) Silver, mass = 420 g, d = 10.5 g/cm.
Best regards.
