What else can I help you with?
A neuron starts to fire an impulse by the influx of what ions?
A neuron fires an impulse by the influx of sodium ions into the cell. This creates a temporary change in the neuron's membrane potential, leading to depolarization and the generation of an action potential.
What is the term for an atom with a change?
An ion. There are positive ions, called cations, and negative ions, called anions.
Can the total ionic equation shows the net change in the equation after spectator ions been removed?
Yes, the total ionic equation shows all the ions involved in the reaction, including the spectator ions. To find the net ionic equation, you can remove the spectator ions from the total ionic equation to emphasize the ions that participate in the actual chemical change.
What is momentum acquired by ions?
The momentum acquired by ions refers to the change in momentum experienced by ions as a result of interactions with other particles or fields. This change in momentum can occur due to collisions, accelerations, or other forces acting on the ions. The momentum acquired by ions is an important concept in the study of ion dynamics and is often used to analyze and understand the behavior of ions in various environments.
What kind of change can ions have?
positive or negative charge. A+
What are speactator ions?
Spectator ions are ions in a chemical reaction that do not participate in the actual reaction but remain in solution. They are present in both the reactants and products and do not change during the course of the reaction. Spectator ions help maintain charge balance in the solution but do not influence the overall outcome of the reaction. In net ionic equations, spectator ions are often omitted to focus on the ions and molecules that directly participate in the chemical change.
What does Na3PO4 change to when dissolved in H2O?
IT GIVES Na+(ion) and PO4-3 IONS WHEN DISSOVED IN WATER .
How can a gas change to a plasma?
gas can change to plasma when high energy state is no longer maintained and ions combine either with other ions or whit electrons to form stable molecules.
What ions cause an acid-base indicator to change?
Hydrogen ions (H+) and hydroxide ions (OH-) cause an acid-base indicator to change color. In an acidic solution, there are more H+ ions present, causing the indicator to appear a certain color. In a basic solution, there are more OH- ions present, resulting in a different color being displayed by the indicator.
How do you calculate protons and in ions?
The protons are always the same as their matching atomic number. This is also true of ions. Protons never change.
Why cant you change the charge of an ion to make formulas?
You can't change the charge because that is changing the very chemical nature of the ion/atom. To make formulas with ions, you use subscripts to change the NUMBER of ions in the formula without changing the CHARGE.
Is a fire a physical or chemical change?
A fire is a chemical change due to the irreversible changes that happen.
