A 5.9 L sample of SIH4 gas at 356 mm Hg pressure and 25°C is allowed to react with O2 gas. What volume of Oz gas, in liters, is required for complete reactio if the oxygen has a
pressure of 407 mm Hg at 25°C?

why is cellular respiration important for homeostasis?

it changes food into energy that the organism can use.

which of the following is most likely to happen if a cell is not able to divide?

the cell will not be replaced when it is damaged.

explanation:

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
