Answer : The correct answer for mass of material = 26.6 Kg
Given : Q = 4720 KJ
Change in Temperature ( ΔT ) = 65 K
Specific heat capacity of material ( c) = 2730
The relation between Q , ΔT , c and m are related by following formula :
Q = m* c*ΔT ,
where Q = Heat or energy absorbed or released
m = mass , c = specific heat ,ΔT = change in Temperature
Plugging value in heat formula :
[[Converting
]]
Dividing both side by
m = 26.6 Kg
Answer:
Well, Aluminum Oxide has a very high melting point. Carbon dioxide has a very low boiling point.
Explanation:
They are both talking about different things, melting and boiling. Aluminum Oxide's melting point is much higher then carbon dioxide's melting point. Hope this help, and good luck on your assignment (if one)

Explanation:
some regions of a polypeptide may coil or fold back on themselves. this is called <u>secondary structure</u> , and the coils or folds are held in place by <u>hydrogen bonds</u>
<u></u>
After translation, primary structure is just the arrangement of amino acids. The interactions between the carbonyl, amino, and side groups of the amino acid polymer backbone inside the chain result in the secondary structure of proteins. These interactions are primarily fueled by hydrogen bonds, which result in the formation of alpha helices and beta sheets, which are the primary features of proteins' secondary structures.
To create a useful three-dimensional structure, tertiary structure requires more interactions within the protein chain. Disulfide bonds between cysteines, hydrophobic contacts, ionic bonding, and dipole-dipole interactions are a few of these interactions. To create a useful, three-dimensional protein structure, several protein chains interact in quaternary structure.
