Hydrogen peroxide breaks down into water and oxygen explain why this is a chemical reaction what are the reactants and products in the reaction?
The breakdown of hydrogen peroxide into water and oxygen is a chemical reaction because it involves the breaking of chemical bonds and the formation of new substances. The reactants in the reaction are hydrogen peroxide (H2O2), and the products are water (H2O) and oxygen gas (O2). This reaction is catalyzed by enzymes in living organisms like catalase.
When ammonium chloride dissolves in a beaker of water the beaker becomes cold to the touch explain this phenomenon?
When the ammonium chloride dissolves in the water, it is an endothermic reaction. The energy for the reaction comes from the water. Since the water is losing energy, the temperature of the solution decreases, which in turn decreases the temperature of the beaker because of heat transfer.
Explain why nitration are usually carried out at comparatively low temperatures?
In most of the nitration processes heat is require but relatively (as compare to sulphonation) low temperature is due to volatile nature of nitrating agent which is usually nitric acid, at higher temperature nitric acid may decompose or may escape from the reaction vessel.
Why does a chemical equation have to be balanced?
Balancing Chemical Equations is absolutely essential if you want to determine quantities of reactants or products. An unbalanced chemical equation gives only the identify of the beginning reactants and the final products using the appropriate formulas as well as the conditions of temperature, physical state, and pressure conditions under which the reaction is to operate under. However an unbalanced equation can say nothing about the quantities involved until the equation has been balanced. A balanced equation assures that the conservation law of matter is obeyed. The total mass of reactants must equal the total mass of products. A balanced equation tells you the proportional quantities of each substance involved.
Nitrogen Oxide and ozone sometimes react to produce nitrogen dioxide and oxygen The collision between the two molecules does not always lead to a reaction Explain why?
Not all collisions between nitrogen oxide and ozone molecules result in a reaction because the molecules need to have sufficient energy and correct orientation for successful reaction. If the molecules collide with insufficient energy or in the wrong orientation, they will simply bounce off each other without forming any new products. This is known as the collision theory.
Explain what it means for a reaction to be endothermic and what would happen to the temperature recorded by a thermometer in an endothermic reaction?
An endothermic reaction absorbs heat from its surroundings to proceed, resulting in a decrease in temperature of the surroundings. This decrease in temperature would be observed on a thermometer, as the heat is being taken in by the reaction rather than being released into the environment.
How do you explain reactant and product?
Reactants are substances that are consumed in a chemical reaction to produce new substances called products. Reactants are present at the beginning of a reaction, while products are formed as a result of the reaction. The reactants undergo chemical changes to form the products during the reaction process.
What does a word equation or a chemical reaction tell you?
I think that a chemical equation tells a chemist that substances you start with and substances you end with
Explain which type of reaction exothermic or endothermic would be required to make a cold and a cold pack or hot pack?
You would have to have an Eacthomatdid reaction of chemcal chance to change a cold pack to a hot pack.

Why do scientist use chemical equations to explain chemical reactions?
Scientists use chemical equations to show the starting materials (reactants) and resulting products in a chemical reaction in a clear and concise manner. It allows them to understand the balance of atoms before and after the reaction, and to calculate the amounts of reactants and products involved. This helps in predicting the outcome of reactions and designing new processes.
What Specializes in rationalizing reactions?
A reaction mechanism is specialized in rationalizing reactions by proposing step-by-step sequences of molecular events that explain how reactants are transformed into products. This approach helps to understand the role of each species involved in the reaction and the factors influencing the reaction's outcome.
What does the law of conservation of explain?
law of coservation states that mass can neither be created nor be destroyed in a chemical reaction. Morover, it tells that the total mass of reactants is equal to the total mass of products....
Did lowering the temperature (step 2) affect the equilibrium Explain your answer?
Yes, lowering the temperature typically affects the equilibrium of a reaction, especially if it is exothermic. According to Le Chatelier's principle, decreasing the temperature shifts the equilibrium position to favor the exothermic direction, producing more products if the forward reaction releases heat. Conversely, for endothermic reactions, lowering the temperature would shift the equilibrium towards the reactants. Therefore, the specific impact on equilibrium depends on the nature of the reaction involved.
How did the discovery of atoms explain the observation that the mass of the products always equals the mass of the reactants in a reaction?
The discovery of atoms provided a fundamental understanding of matter, showing that chemical reactions involve the rearrangement of these indivisible particles. According to the law of conservation of mass, atoms are neither created nor destroyed in a chemical reaction; they are simply transformed from reactants to products. This principle explains why the total mass of the reactants before a reaction equals the total mass of the products afterward, as the same atoms are present, just in different combinations. Thus, the atomic theory supports the observation of mass balance in chemical reactions.
What is term used for the height of the energy barrier the reactants must overcome in order to form products in a reaction?
The term used for the height of the energy barrier that reactants must overcome to form products in a reaction is called the "activation energy." This energy barrier determines the rate at which a reaction proceeds; higher activation energy typically results in a slower reaction rate. Activation energy is a crucial concept in chemical kinetics and helps explain why some reactions occur more readily than others.
What is the difference between an exothermic and an endothermic chemical reaction?
In an exothermic reaction, energy is released in the form of heat, making the surroundings warmer. In contrast, an endothermic reaction requires energy input from the surroundings to proceed, making the surroundings cooler as it absorbs heat.
