"MASS BEFORE MUST EQUAL MASS AFTER" refers to the principle of conservation of mass, which states that in a closed system, the total mass remains constant over time, regardless of the processes occurring within the system. This means that during any chemical reaction or physical change, the mass of the reactants must equal the mass of the products. This fundamental concept is crucial in chemistry and physics, as it helps in understanding how substances interact and transform without any loss or gain of mass.

What does it mean when they say mass is conserved in a mixture?
When it is said that mass is conserved in a mixture, it means that the total mass of the components before mixing is equal to the total mass after they are combined. This principle is based on the law of conservation of mass, which states that mass cannot be created or destroyed in a closed system. Therefore, in a mixture, even though the individual substances may change in form or distribution, their total mass remains constant.
What is 1000 cemiliter equal to?
You must mean "centilitre". I believe it would be 10 litres, or 1 decalitre.
What does amu mean in the atomic mass of an element aside of it?
AMU stands for atomic mass unit. It is a unit of mass used to express atomic and molecular weights. One atomic mass unit is defined as a mass equal to one twelfth the mass of a carbon-12 atom.
In chemical reactions what does law of conservation of mass mean?
The law of conservation of mass states that in a closed system, the total mass of reactants must equal the total mass of products during a chemical reaction. This means that matter cannot be created or destroyed; it can only change forms. Therefore, the number of atoms and their mass remain constant throughout the reaction, ensuring that all reactants are accounted for in the products. This principle is fundamental to balancing chemical equations and understanding chemical processes.
What does MSun mean?
MSun typically refers to a solar mass unit, which is a unit of measurement used in astronomy to express the mass of a celestial body in terms of the mass of our Sun. It is equal to the mass of the Sun - approximately 2 x 10^30 kilograms.
What does E equal mc2 equation mean?
Energy is equal to Mass multiplied by the speed of light squared
What is mean by center of mass?
Center of mass is defined as the point about which the sum of mass moment vectors of all the points of the body is equal to zero.
What does equal parts by mass mean?
Equal parts by mass means that the quantities being compared have the same weight. For example, if two substances are combined in equal parts by mass, it means that they are mixed in a 1:1 ratio based on weight. This measurement ensures that each substance contributes equally to the overall mass of the mixture.
How does law of the conservation of mass apply to chemical reactions?
The Law of Conservation of Mass applies to chemical changes. When considering a chemical change this would mean that the total mass of all of the reactants in the chemical reaction is equal to the total mass of products in the chemical reaction.
What does gram mean in math?
a metric unit of mass equal to one thousandth of a kilogram.
What does law of conservation of mass mean?
The law of conservation of mass means that if you start out with 100 grams of reactants, you will end up with 100 grams of products. In addition, the number and types of atoms in the reactants and products will be the same.
Equal volumes always mean equal masses?
Not necessarily. Equal volumes do not always mean equal masses because different substances have different densities. Denser substances will have more mass in a given volume compared to less dense substances.
What do atomic number and atomic mass mean?
The atomic number is equal to either the number of electrons or the protons of a particular atom. The atomic mass in a.m.u. is equal to the sum of protons and neutrons in an atom.
Does equal sign proceeds a formula?
If you mean in Excel, yes: you must always start a formula with an equal sign.
What does it mean when they say mass is conserved in a mixture?
When it is said that mass is conserved in a mixture, it means that the total mass of the components before mixing is equal to the total mass after they are combined. This principle is based on the law of conservation of mass, which states that mass cannot be created or destroyed in a closed system. Therefore, in a mixture, even though the individual substances may change in form or distribution, their total mass remains constant.
Can an obtuse triangle have equal sides?
if you mean ALL sides equal then no, because for a triangle to have ALL equal sides all angles must be equal (60 degrees), and an obtuse triangle must have an angle with 91 or more degrees. but if you mean TWO sides equal then yes. for example, a triangle with angles 40, 40 & 100 degrees would have two equal sides.
What does the law of the conservation of mass mean?
The law of conservation of mass, also known as the principle of mass/matter conservation, states that the mass of an isolated system (closed to all transfers of matter and energy) will remain constant over time. The law implies that mass can neither be created nor destroyed, although it may be rearranged in space and changed into different types of particles; and that for any chemical process in an isolated system, the mass of the reactants must equal the mass of the products.
