When two substances react chemically to produce a new substance what is TRUE of the mass of the two substances compared to the mass of the new substance?
Same. Mass is not changed.
What is a compound in chemistry?
A compound is a pure substance consisting of two or more chemically combined elementsDo you mean compound if so a compound is 2 elements chemically bonded together
Definition of a chemical reaction?
A combination, or synthesis, reaction, is one in which two simpler substances chemically combine to form a more complex substance. For example, the reaction between hydrogen and oxygen to form water is a combination (synthesis) reaction. 2H2 + O2 --> 2H2O
How do group II elements differ in vigor as they react with water?
The alkaline earth metals shown in column 2 of a wide form periodic table react more vigorously with water the greater their atomic mass.
Is calcium carbonate a compound or a mixture?
Calcium Carbonate is a compound as it contains 3 different elements (calcium, carbon and oxygen) that are chemically combined.
When two element chemically react the mass of the product is?
After the law of mass conservation the mass of reactants is equal to the mass of products.This is a extremely important law in chemistry.The Russian chemist Mikhail Lomonosov described this principle in 1748.
When two substances react chemically to produce a new substance what is TRUE of the mass of the two substances compared to the mass of the new substance?
Same. Mass is not changed.
How would a synthesis reaction cause the mass of a product to be higher than the metal in a crucible?
Heating a metal in a crucible can cause the metal to react with the surrounding gases. thus, when weighing the metal after heating, the mass increases because of the addition of the gaseous elements

What was Lavoisier's discovery about mass not being able to be made or destroyed?
Law of Conservation of Mass. The the number of the compound or elements in the reactant is equal to the product.
What substance that contains 2 or more elements chemically combined in a fixed proportion?
A substance made of two or more elements chemically combined in a specific proportion is called a compound. A substance composed of two or more elements combined chemically in a fixed proportion by mass is called a compound. A chemical compound can be held together by a covalent bond or an ionic bond.
When 53.6 grams of calcium carbonate react with plenty of aluminum fluoride how many grams of each product can be produced?
mass of CaF3 = 61.96g mass of Al2CO3 =61.104 g

What is the body of the sun made of?
Chemically, about 75% of the Sun's mass consists of hydrogen, 23,3% - helium. The remainder (1.7%, which nonetheless equals 5,7 mass of Earth) consists of heavier elements, including oxygen, carbon, neon and iron, among others.
