l. Given the balanced equation representing a reaction:What occurs during this reaction?1) Energy is absorbed as bonds are broken.2) Energy is absorbed as bonds are formed.3) Energy is released as bonds are broken4) Energy is released as bonds are formed.

Answers

1) energy is absorbed and bonds are broken

This is due to two reasons
1. The breaking of bonds requires and input energy. The formation of bonds is a release on energy. As bond breaking requires energy, it is only natural that once of the answers would involve the absorption of energy.
2. O2 is the covalent bond between two oxygen molecules. When these molecules are separated the bond is broken. As such the answer must be 1

. SE7.12D Which of the following statements accurately represents the differences inplant and animal cells?
Only plant cells have a cell wall, chloroplasts, and a large vacuole.
Only animal cells have a cell wall, chloroplasts, and a large vacuole.
Only plant cells have a cell membrane, mitochondria, and cytoplasm.
Only animal cells have a cell membrane, mitochondria, and
cytoplasm.
CLEAR ALL

Answers

Features which are found in plant cellsonly are the chloroplast, large vacuole and cell wall.

Plants and animal cells consists of the following parts ; Mitochondria, cell membrane, vacuole, cytoplasm and so on.

The vacuole present in animal cells are much smaller than those found in plant Cells. Hence, vacuole in animal cells are called small vacuole

Plant cells also consists of cell wall, chloroplast and a large vacuole. All these are missing in animal cells.

Therefore, Only plant cells have "acellwall,chloroplastsandalargevacuole."

In the "Méthode Champenoise," grape juice is fermented in a wine bottle to produce sparkling wine. The reaction is the following. C6H12O6(aq) → 2 C2H5OH(aq) + 2 CO2(g) Fermentation of 754 mL of grape juice (density = 1.0 g/cm3) is allowed to take place in a bottle with a total volume of 840. mL until 13% by volume is ethanol (C2H5OH). Assuming that the CO2 is insoluble in H2O (actually a wrong assumption), what would be the pressure of CO2 inside the wine bottle at 21°C? (The density of ethanol is 0.79 g/cm3.)
