What else can I help you with?
Is hydrogen lost when a chemical reaction is a reduction?
No, hydrogen is gained during a reduction reaction, not lost. Reduction involves the gain of electrons and hydrogen atoms.
What states that the reactants mass equals products mass?
The law of conservation of mass states that the total mass of the reactants in a chemical reaction is equal to the total mass of the products. This means that no mass is gained or lost during a chemical reaction, only rearranged.
Are valence electrons lost gained or shared during a chemical reaction?
Valence electrons can be both lost and gained during a chemical reaction, depending on the types of elements involved. For example, in ionic bonding, valence electrons are typically lost or gained to achieve a full outer shell. In covalent bonding, valence electrons are shared between atoms to complete their outer shells.
What subatomic particles is lost or gained during a chemical reaction?
During a chemical reaction, electrons are the subatomic particles that are lost or gained. When an atom loses electrons, it becomes positively charged and when it gains electrons, it becomes negatively charged. This process is responsible for the formation of chemical bonds and the creation of new compounds.
What chemical equation shows that no atoms are lost during a chemical reaction?
The law of conservation of mass states that no atoms are lost during a chemical reaction. This can be represented by a balanced chemical equation, where the number of atoms of each element remains the same on both sides of the reaction. For example, the equation for the reaction between hydrogen gas and oxygen gas to form water is: 2H2 + O2 -> 2H2O.
What is gained in a chemical reaction?
Electrons are the ones gained or lost in a chemical reaction. Electrons are gained in oxidation and lost through the chemical reaction known as reduction.
Why do reactions have to he balanced?
atoms are not lost or gained in a chemical reaction
How does one recognize redox reaction?
if oxidation states change, it is a redox reaction
The idea that atoms are gained nor lost during a chemical reaction is called the law of?
The idea that atoms are neither gained nor lost during a chemical reaction is called the law of conservation of mass. This principle states that the total mass of the reactants must equal the total mass of the products in a chemical reaction.
Does a chemical equation show the number of atoms lost during a chemical reaction?
Yes, a chemical equation shows the number of atoms of each element involved in a chemical reaction, including those gained, lost, or rearranged. The Law of Conservation of Mass states that mass is conserved in a chemical reaction, so the total number of atoms before and after the reaction must be the same.
What is matter in a chemical process its not lost nor gained?
In a chemical process, matter is not lost nor gained; it is simply rearranged into new combinations. This is known as the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction, only converted into different forms.
What is the law of indestructibility of matter?
No weight is ever gained or lost in a chemical reaction.
Elements can be lost or gain in chemical reaction?
Elements cannot be lost/gained: this is the law of mass conservation.
Is hydrogen lost when a chemical reaction is a reduction?
No, hydrogen is gained during a reduction reaction, not lost. Reduction involves the gain of electrons and hydrogen atoms.
How many electrons are lost or gained in a chemical reaction?
There is zero NET loss or gain of electrons
What states that the reactants mass equals products mass?
The law of conservation of mass states that the total mass of the reactants in a chemical reaction is equal to the total mass of the products. This means that no mass is gained or lost during a chemical reaction, only rearranged.
Are valence electrons lost gained or shared during a chemical reaction?
