A spontaneous reaction is one that favors the creation of products under the reaction's current conditions.
What is spontaneous reaction?
A spontaneous reaction is exergonic and has a negative delta G. The system's enthalpy, or total energy, must decrease and its entropy, or disorder, must rise for a chemical reaction to occur with a net release of free energy (- delta G). The energy needed for cellular function comes from spontaneous reactions.
What is importance of spontaneous reactions in the metabolism of a cell?
- Chemical reactions take place in steps to produce and break down complex molecules as part of cellular activities.
- While some of these chemical processes take energy to complete, others happen spontaneously and release energy.
- Cells must continuously produce additional energy to replace the energy spent by the numerous energy-intensive chemical reactions that take place all the time, just as living beings must continuously consume food to replenish their energy stores.
- The term "cell metabolism" refers to all of the chemical processes that occur within of cells, including those that use or produce energy.

Answer:
Plasma
Explanation:
Plasma carries water, salts, and enzymes. The main role of plasma is to take nutrients, hormones, and proteins to the parts of the body that need it. Cells also put their waste products into the plasma. The plasma then helps remove this waste from the body.

Answer:
Which of the following equations are balanced correctly?
2Ag2O → 4Ag + O2
Zn + HCl → ZnCl2 + H2
Cu + H2O → CuO + H2
2C4H10 + 13O2 → 8CO2 + 10H2O
Explanation:
It practically means that the air in the city has less than a third of water vapor it could contain under the same circumstances.
Relative humidity is the ratio of water vapor that the air contains to the maximum amount it could carry at the same temperature.
When the humidity is high, the water vapor in the air is a variety more, and vice versa.
