The substance which undergo chemical change in areaction are called?
Reactants are the substances that undergo chemical changes in a reaction. They are the starting materials that are transformed into products during a chemical reaction.
A uranium235 sample starts with 200 atoms and 700 million years later there are 100 atoms What is the halflife of uranium235?
700 milliion years. The definition of half-life is the period of time during which one-half of the atoms of an element undergo decay into other elements.
What changes occur when a chemical reaction?
During a chemical reaction, bonds between atoms are broken and new bonds are formed, resulting in the rearrangement of atoms to form new molecules with different properties. Energy is either absorbed or released during the reaction, and the total mass of the reactants is conserved in the products.
When energy is absorbed during a chemical reaction the reaction is classified as what reaction?
Endothermic reaction.
What is true about the balance of mass in a fusion reaction?
In a fusion reaction, the total mass of the reaction products is less than the total mass of the initial reactants due to the conversion of mass into energy according to Einstein's famous equation E=mc^2. This difference in mass is known as the mass defect, and the lost mass is converted into energy during the fusion reaction.
What substances during chemical reactions are involved?
The initial substances in a chemical reaction are called reactants.
What is a particle released during the fission of uranium235?
One of the particles released during the fission of uranium-235 is a neutron. When uranium-235 undergoes fission, it splits into two smaller atoms along with several neutrons. These neutrons can then go on to initiate additional fission reactions in a chain reaction.
What are the steps to a chain reaction?
A chain reaction typically involves three steps: initiation, propagation, and termination. During initiation, the reaction is triggered by an initial event. In propagation, products from the initial reaction continue to react, creating more products. Termination occurs when the reaction eventually stops due to the depletion of reactants or other factors.
The reactant are the new materials produce during a chemical reaction?
No. The reactants are the initial materials that undergo chemical reaction; the new materials produced have the unsurprising name "products".
The substance which undergo chemical change in areaction are called?
Reactants are the substances that undergo chemical changes in a reaction. They are the starting materials that are transformed into products during a chemical reaction.
After the reaction how much octane is left?
To determine how much octane is left after a reaction, you would need to know the initial amount of octane, the stoichiometry of the reaction, and the amount of other reagents/reactants consumed during the reaction. Without this information, it is impossible to provide an exact answer.
A uranium235 sample starts with 200 atoms and 700 million years later there are 100 atoms What is the halflife of uranium235?
700 milliion years. The definition of half-life is the period of time during which one-half of the atoms of an element undergo decay into other elements.
What molecule is the reactant in the first reaction of glycolysis?
The reactant in the first reaction of glycolysis is glucose. Glucose is converted into glucose-6-phosphate by the enzyme hexokinase during the initial step of glycolysis.
What happens when an atom is not oxidized or reduced during a reaction?
When an atom is not oxidized or reduced during a reaction, it means that its oxidation state remains unchanged. This implies that the atom neither gained nor lost electrons during the reaction, maintaining its initial valence state.
What happens to the temperature when the mass is increased in a chemical reaction involving magnesium and hydrochloric acid?
Increasing the mass of magnesium in a reaction with hydrochloric acid will not directly affect the temperature of the reaction. The temperature will be determined by the amount of heat released or absorbed during the reaction, which depends on the specific reaction and the initial conditions.
What changes occur when a chemical reaction?
During a chemical reaction, bonds between atoms are broken and new bonds are formed, resulting in the rearrangement of atoms to form new molecules with different properties. Energy is either absorbed or released during the reaction, and the total mass of the reactants is conserved in the products.
