What is the percentage composition of water?

Water makes up about 70 percent of the human body. The water content in the body of male is more than that in the body of female, and the water content in the body of young people is more than that in the elderly. The water content in the body of newborn is about 70%~75% shui. The amount of water in human tissues is also different: about 10 percent of the water in bone and cartilage; Water in fat accounts for about 20%~35% of total fat; The distribution of water in muscles has reached up to about 70% of the total muscle mass. In the blood plasma, except 6%~8% of plasma proteins, 0.1% of glucose and 0.9% of inorganic salts, the rest are all water, accounting for about 91%~92% of the total plasma.

Explanation:

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.

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.
