We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What else can I help you with?
In a correctly written nuclear equation what is true about the total mass number on the reactant side as compared to the total mass number on the product side?
the total mass number should be equal on both sides. conservation of mass law.
What is mass number made of?
The mass number of an atom is made up of the total number of protons and neutrons in its nucleus. The mass number represents the total mass of an atom and is typically written as a superscript before the chemical symbol of an element in a chemical equation or notation.
As the equation is written which element is not in balance Explain?
An equation written may or may not be balanced. It is balanced if the number of elements on both sides of the arrow, that is before and after the reaction, is equal. Sometimes the number of elements is not the same on both sides of the arrow, then we need to balance the equation. This is done in accordance to the law of conservation of mass which states that the mass of a substance does not get destroyed or created due to a chemical reaction.
What equation tells you how to calculate the number of neutrons in an atoms?
This equation is:Mass number - number of protons = number of neutronsMass number is the sum of protons and neutrons and has a value near the Atomic Mass of an isotope.
What is meant by an unbalanced equation?
An unbalanced equation is a chemical equation that does not have an equal number of atoms of each element on both sides of the equation. This means that the law of conservation of mass is not satisfied, as the total mass of the reactants does not equal the total mass of the products.
What equation do you use to find the number of neutrons in an element?
Number of neutrons = mass number - number of protons
Explain how the balancing of chemical equation shows that mass is conserved?
Balancing a chemical equation ensures that the number of atoms of each element on the reactant side is equal to the number on the product side. This conservation of atoms implies the conservation of mass. When the equation is balanced, the total mass of the reactants is equal to the total mass of the products, demonstrating the law of conservation of mass.
What is mass Stoichiometry?
The number of moles in the equation of B DIVIDED BY the number of moles in the equation of A ANSWER TIMES the molar mass of B OVER 1. A is the the known compound, B is the one your trying to find out.
How does chemical equations show a conservation of mass?
A properly written chemical equation will always show the same number of atoms of each elemental on each side, showing that no atoms are created or destroyed in the chemical reaction.
When balancing a nuclear equation what two quantities are conserved when balancing a nuclear equation?
In a nuclear equation, the total number of protons and neutrons is conserved. This means that the sum of the mass numbers and the sum of the atomic numbers must be the same on both sides of the equation before and after the reaction.
What is the sum of twice a number and 5 is 17 written as an equation?
The phrase "the sum of twice a number and 5 is 17" can be translated into an equation. Let the unknown number be represented by ( x ). The equation can be written as ( 2x + 5 = 17 ).
How can use the law of conservation of mass to help you balance a chemical equation?
The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction, so the number of atoms of each element must be the same on both sides of the equation. By balancing a chemical equation, you ensure that the total number of atoms of each element in the reactants is equal to the total number of atoms in the products, thus preserving mass.
