How do chemical reaction change substances?
After a chemical reaction, some of the bonds have been broken, and some new bonds have been formed. So, that's how a substance is changed after the reaction.
What goes into a reaction and what comes out of a reaction?
Reactantd go into a reaction and the products come out of a reaction. For want of a better expression the atoms in the reactants play 'musical chairs' to form the products. e.g. Hydrochloric Acid and potassium hydroxide are the reactants and potassium chloride and water are the products. HCl(aq) + KOH(aq) = KCl(aq) + H2O(l) Notice how the atoms all move place.
When the heat shifts the direction of the reaction there has been a change in concentration and equilibrium will then be affected?
Yes, a change in temperature can shift the equilibrium of a reaction by changing the concentrations of reactants and products. The direction of the shift depends on whether the reaction is endothermic or exothermic. An increase in temperature will favor the endothermic reaction, while a decrease will favor the exothermic reaction.
How do the energy diagrams show that energy is conserved in chemical reactions?
Energy diagrams illustrate the energy changes during chemical reactions, depicting the energy of reactants and products along with the activation energy required for the reaction. In an exothermic reaction, the energy of the products is lower than that of the reactants, indicating that energy has been released. Conversely, in an endothermic reaction, the products have higher energy than the reactants, reflecting energy absorption. Overall, the total energy remains constant throughout the reaction, demonstrating the principle of energy conservation.
What type of change was the magnesium reaction?
The magnesium reaction is a type of chemical change. In this reaction, magnesium reacts with oxygen to form magnesium oxide, resulting in a transformation of the original substances into new products with different chemical properties. This change is characterized by the breaking and forming of chemical bonds, indicating that a new substance has been created.
In an exothermic reaction is the energy of the products higher or lower than that of the reactants?
In an exothermic reaction the energy of the products is less than that of the reactants.
When does a chemical reaction go to completion?
A chemical reaction goes to completion when all the reactants have been fully converted into products, with no remaining reactants left.

What observations would you make when checking a delivery?
Make sure it's in date and nothing been opened or bumbled
What is an hypothetical reaction?
A hypothetical reaction refers to a chemical reaction that is proposed or imagined based on theoretical considerations. It may not have been observed or documented experimentally, but is used to predict the products or outcomes of a given set of reactants under certain conditions.
How can you tell from a graph when a reaction is finished?
In a graph of reaction progress versus time or concentration, a finished reaction typically shows a plateau where the values remain constant. This indicates that the reactants have been fully consumed and the products have reached equilibrium. The reaction rate becomes zero at this point.
What does it mean to say a reaction proceeds to 10 percent completion?
It means 10% of reactants have been converted into products and 90% are still there as reactants.
When the heat shifts the direction of the reaction there has been a change in concentration and equilibrium will then be affected?
Yes, a change in temperature can shift the equilibrium of a reaction by changing the concentrations of reactants and products. The direction of the shift depends on whether the reaction is endothermic or exothermic. An increase in temperature will favor the endothermic reaction, while a decrease will favor the exothermic reaction.
What type of reaction is H2O plus CO2?
It is synthesis since your adding them together other wise decomposition is breaking them apart
What is catailysis?
It is an enzyme that allows for a reaction to accur sooner then normal. The catalysis makes the activation energy needed by the reaction less then what would have been normally. Allowing for a reaction to happen faster.
