Which describes fat? a: a carbohydrate that produces energy b: a nucleic acid that directs cell function c: a lipid that stores energy d: a protein that speeds up a chemical reaction

Freezing and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

Using the thermodynamic information in the aleks data tab, calculate the standard reaction free energy of the following chemical reaction: →+p4o10s6h2ol4h3po4s round your answer to zero decimal places.
