What substance in body fluids determines most of their chemical and physical reaction?
The concentration of hydrogen ions (pH) is a crucial factor that determines the chemical and physical reactions in body fluids. Maintaining a stable pH level is essential for various enzymatic reactions and overall physiological functioning.
Does smell change with a physical change?
Smell is a physical property. It it caused by small amounts of the airborne substance undergoing chemical reactions with receptors in your nose.The smell of perfume is a physical not a chemical
What physical factors control the rate of chemical reactions?
Physical factors that control the rate of chemical reactions include temperature, pressure, concentration of reactants, and surface area of the reactants. Temperature influences the kinetic energy of particles, pressure affects the collision frequency of molecules, concentration determines the number of reactive collisions, and surface area determines the contact area between reactants.
How are physical and chemical reactions different?
Physical reactions mean that the substance hasn't been altered in terms of its composition. For example, liquid water turning into an ice cube is a physical change. It is still H2O - just different form. However, burning paper is chemical change, since ash + H2O + CO2 is not paper.
Is texture a chemical property of a plastic spatula?
No, texture is a physical property of a plastic spatula. Chemical properties describe the behavior of a substance in reactions and interactions with other substances.
What substance in the body fluids determines most of their chemical and physical reactions?
Electrolytes!
Substance in body fluids that determines most of their chemical and physical reactions?
According to Marieb, 8th edition, "Electrolytes are the most abundant solutes in body fluids and determine most of their chemical and physical reactions"

What is the significance of the variable "m" in chemistry and how does it relate to chemical reactions or properties?
In chemistry, the variable "m" often represents the mass of a substance. It is significant because mass plays a crucial role in chemical reactions and properties. The mass of reactants determines the amount of products formed in a reaction, and the mass of a substance can affect its physical and chemical properties.
What are reversibile reactions?
Reversible reactions usually involve a reaction that changes the physical state of the substance, not the chemical properties
Is reactions a chemical or physical?
Reactions can be both chemical and physical. Chemical reactions involve breaking and forming chemical bonds leading to the formation of new substances. Physical reactions involve changes in state, shape, or form of a substance without changing its chemical composition.
Is a solid at 98 degrees a physical or chemical property?
It is purely a Physical Property. Fusing (melting) involves no chemical reactions. The melting point of a substance is hard wired in the physical properties of a substance.
Is viscosity physical property or chemical property?
Viscosity is a physical property of a substance, which describes its resistance to flow or deformation. It is determined by the intermolecular forces within the substance and is not a result of any chemical changes or reactions.
What has the author K Gierschner written?
K. Gierschner has written: 'Training in food science and technology as a specialisation of an education in physical, chemicaland biological sciences'
What is a change that alters the form or appearance of a substance but does not make it into other substance?
It is considered a physical change. A chemical change involves chemical reactions that change the substance into another substance. A physical change typically only modifies the form or phase.
How does movement of atoms affect the behaviour of the substance?
The movement of atoms determines the physical state of a substance (solid, liquid, gas) and influences its properties such as density, viscosity, and conductivity. The speed and direction of atomic movement also impact chemical reactions by determining the likelihood of collisions and interactions between atoms.
What are the chemical reactions involves in sublimation?
Sublimation, per se, does not involve any chemical reactions. It is simply a physical change of a substance going from a solid to a gas without passing through the liquid phase.
