Individual organisms live together in an ecosystem and depend on one another. Other organisms have to get their food by eating other organisms.
Answer:
a) 0.2118 mol of I₂ is produced.
b) 49.93 g of I₂ is produced.
Explanation:
a) The balanced equation shows that to produce 1 mol of I₂ we need 2 mol of CuCl₂ . Therefore, the amount of I₂ produced will always be half the amount of CuCl₂ given.
b) In order to calculate the mass of I₂ produced we need to know its molar mass:
Each mole of I₂ weighs 253.8 g, therefore MM = 253.8 g/mol.
Answer:
The possible source of errors as regard the Procedure are:
- The final temperature was measured before the temperature stopped changing
- The cap of the calorimeter was not closed immediately after mixing
- temperatures where not measured right before mixing
Explanation:
The procedure referred to should a experiment with regards heat

Answer:
B. primary; secondary
Explanation:
Small changes in primary structure can result in large changes in protein shape and function. Secondary structure describes regions where the polypeptide is folded into localized shapes. There are two types of secondary structure (alpha helix and Beta pleated sheet).
