A device that uses energy of chemical reactions to separate positive and negative charges?
An electrolytic cell utilizes chemical reactions to generate an electric current that separates positive and negative charges at the electrodes. This separation occurs due to the movement of ions in the solution. The cell typically consists of two electrodes immersed in an electrolyte solution where oxidation and reduction reactions take place.
What is the negative color of silver nitrate?
The silver nitrate is originally clear and transparent. Without any chemical reactions or negative ions the color does not change. However, the color of the negative silver nitrate is cloudy and has a whitish, silver, color to it.
Why negative catalyst called inhibitors?
Negative catalysts (inhibitors) are those substances (or factors) which slow down the chemical reactions by decreasing the required activation energy for the reaction, for example the decomposition of Hydrogen peroxide may be slow down by adding a small amount of Glycerin in it.
What is the unique chemical component of a Gram Negative cell wall?
The unique chemical component of a Gram-negative cell wall is lipopolysaccharide (LPS), which consists of lipid A, core polysaccharide, and O antigen. LPS is responsible for the endotoxic properties of Gram-negative bacteria.
What is a small particle that moves outside the nucleus and carry a negative charge?
Electrons are small particles that move outside the nucleus of an atom and carry a negative charge. They play a key role in chemical reactions and the behavior of atoms.
Are chemical reactions always spontaneous when H is negative and S is negative?
No, when H and S are both negative, the reaction will only be spontaneous below a certain temperature
Reduction reactions are?
a chemical reaction in which a reactant gains one or more electrons more negative in charge!!
What orbits nucleus negative charge?
Electrons orbit the nucleus of an atom and carry a negative charge. The number and arrangement of electrons determine an atom's chemical properties.
What would it mean if the change in mass is negative?
A negative change in mass means that the object has lost mass. It could be due to factors such as evaporation, chemical reactions, or loss of particles.
How is endothermic reactions differ from exothermic reactions?
Endothermic reactions absorb heat from the surroundings, causing a decrease in temperature. In contrast, exothermic reactions release heat into the surroundings, leading to an increase in temperature. Endothermic reactions have a positive enthalpy change, while exothermic reactions have a negative enthalpy change.
Which feedback mechanisms maintain equilibrium of systems like turgor pressure temperature and chemical reactions?
both negative and positive feedback
A device that uses energy of chemical reactions to separate positive and negative charges?

The cell typically consists of two electrodes immersed in an electrolyte solution where oxidation and reduction reactions take place.
What are slowed reactions?
Chemical reactions that have high activation energy, with multiple intermediates and transitions states that have higher activation energy than the initial requirement, but which still have a negative Gibbs free energy change.
What is the negative color of silver nitrate?
The silver nitrate is originally clear and transparent. Without any chemical reactions or negative ions the color does not change. However, the color of the negative silver nitrate is cloudy and has a whitish, silver, color to it.
Is silica magnetic?
No, silica is not magnetic. It is a chemical compound composed of silicon and oxygen and does not possess magnetic properties.
Which of an electrons are involved in chemical reactions?
Valence electrons, which are the electrons in the outermost energy level of an atom, are the ones involved in chemical reactions. These electrons determine the atom's ability to form bonds with other atoms.
Why negative catalyst called inhibitors?
Negative catalysts (inhibitors) are those substances (or factors) which slow down the chemical reactions by decreasing the required activation energy for the reaction, for example the decomposition of Hydrogen peroxide may be slow down by adding a small amount of Glycerin in it.
