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 principle can be applied to all chemical reactions?
The principle of conservation of mass can be applied to all chemical reactions. It states that the total mass of the reactants must equal the total mass of the products, as no atoms are created or destroyed during a chemical reaction.
What chemical reaction is written to show that mass is conserved?
The chemical reaction that shows conservation of mass is the Law of Conservation of Mass, which states that the total mass of reactants must equal the total mass of products in a chemical reaction. This can be represented by the balanced chemical equation, where the number of atoms of each element on both sides of the equation must be equal.
How can you justify that a reaction between magnesium and oxygen is a redox reaction whioe the reaction shows only addition of oxygen?
In any redox reaction, at least one reactant is reduced and at least one reactant is oxidized. In the reaction between magnesium and oxygen, the magnesium atoms are oxidized because they lose electrons and the oxygen atoms are reduced because they gain electrons. Furthermore, the premise of the question is erroneous: The reaction does not as alleged show only addition of oxygen; instead it shows combination of magnesium and oxygen to form a new chemical entity, the compound magnesium oxide.
A substance that shows a decrease in oxidation number during chemical reaction?
A substance that shows a decrease in oxidation number during a chemical reaction is being reduced. Reduction involves a decrease in the oxidation number of an element. This indicates a gain of electrons by the substance.
What do the atoms do during a reaction that shows they obeyed the conservation of mass?
no the correct answer was 2.7 * 10^17 J of energy is produced. Apex-Answers
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.
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 equation shows conservation of atoms?
The equation that shows conservation of atoms is the balanced chemical equation, which states that the total number of atoms of each element in the reactants must equal the total number of atoms of each element in the products. This equation demonstrates that atoms are neither created nor destroyed in a chemical reaction, but are rearranged to form new substances.
What Balanced chemical equations demonstrate?
When you balance an equation, the coefficients you end up with represent the molar relationships between the substances. Like: N2 + 3H2--> 2NH3 shows that for every three moles of H there are 2 moles NH3 and 1 mole N
How does the diagram show that mass has been conserved in this reaction?
Because there are three groups in substance Q and substance R, and there are three atoms in substance P.
What information is presented in a chemical equation?
A chemical equation presents the chemical formulas of reactants and products involved in a chemical reaction, along with the symbols and coefficients representing the amounts of each substance. It also shows the conservation of atoms (mass) and charge before and after a reaction.
What is the environment that shows changes of matter?
The environment that shows changes in matter is known as a chemical reaction. During a chemical reaction, the atoms and molecules of substances interact and rearrange to form new substances with different properties. These changes can involve the breaking and formation of chemical bonds.
What is the completed balanced chemical reaction for H2S plus CuSO4?
The balanced chemical equation for the reaction between H2S (hydrogen sulfide) and CuSO4 (copper(II) sulfate) is: H2S + CuSO4 → CuS + H2SO4 This equation is balanced as it shows the conservation of atoms of each element on both sides of the reaction.
The coeficients in a chemical equation indicate?
The coefficients in a chemical equation indicate the relative number of moles of each reactant and product involved in the reaction. They are used to balance the equation so that the law of conservation of mass is upheld, ensuring that atoms are neither created nor destroyed during a chemical reaction.
What principle can be applied to all chemical reactions?
The principle of conservation of mass can be applied to all chemical reactions. It states that the total mass of the reactants must equal the total mass of the products, as no atoms are created or destroyed during a chemical reaction.
How does a correctly written chemical equation show that atoms are not lost in a chemical equation?
By having the same numbers of atoms of each kind of element present in the equation in the written numbers (coefficient multiplied by subscript) of each kind of element on both sides of the equation.
