Which is an accurate description of what occurs when a log burns? a. energy is created as the log burns b. the compounds that make up the log are converted into fire, heat, and energy. c. as the log burns, the nuclear binding energy of the molecules in the log is released. the nuclear binding energy is transformed into the light and heat of the fire. d. the molecules present in the log are transformed into molecules that contain less energy than the original molecules. the energy difference is the heat of the fire?

d. The molecules present in the log are transformed into molecules that contain less energy than the original molecules. The energy difference is the heat of the fire

Explanation:

When a log of wood burns, Oxygen must be present because it is a combustion reaction. A log of wood is composed of organic materials and the main organic material present is Carbon.

Due to the fact that Oxygen is present, Carbon reacts with Oxygen to form Carbon dioxide which contains lesser energy than Carbon.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.

explanation:

the correct answer is: d. the saltine and pretzel are made of flour, yeast, and baking soda, and salt. the pecan contains no flour but it does contain fats. the pecan is a nut that can be consumed as a healthy snack. first of all, pecans are a source of fat (monounsaturated fat), but they provide less fat than some other nuts. pecans are a rich source of dietary fiber, manganese magnesium, phosphorus, thiamin, vitamin e…
