Even though lipids and carbohydrates are made from the same elements, why is it easy to tell them apart when viewing a model of each?

Carbohydrates have a hexagon shaped chain which is easy for digestion and breaking down. The lipids are a long straight chain that does not break down easily (typically stored as fatty tissue, and slowly broken down).

I’d have to say no because without oxygen in the water the fish would all be dead. so if you want to fish for dead fish, pick the ponds with the lowest oxygen concentrations.

Answer : option c) heat is released during the process.explanation :

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
