How would you know if a reaction was endothermic or exothermic?
An endothermic reaction is one in which thermal energy, or heat, is absorbed. If heat is absorbed in the reaction process, it is endothermic. By monitoring the temperature of the reactants in a reaction, an observer could identify an endothermic reaction through observation of a decrease in the temperature.
If you multiply the following reaction by 2 to be an intermediate reaction in a Hess's law problem what would be the final value for the enthalpy of reaction you use for this intermediate reaction?
When you multiply a reaction by a factor, you also multiply the enthalpy change by the same factor. Therefore, if you multiply the reaction by 2, the final value for the enthalpy of reaction for the intermediate reaction will also be multiplied by 2.
What kind of reaction is bacl2 na2s04---baso4 2nacl?
The reaction between BaCl2 and Na2SO4 is a double displacement reaction, also known as a precipitation reaction. In this reaction, BaSO4 and 2NaCl are formed as products when BaCl2 and Na2SO4 react. This reaction involves the exchange of ions between the reactants to form new compounds.
A dehydration reaction can also be called?
A dehydration reaction can be (and often is) called dehydration synthesis, as the process involves synthesizing large compounds from smaller ones by removing the water from them (hence the dehydra- )
A dehydration reaction can also be called a?
An "elimination" reaction or "condensation" reaction.
What is sytemic?
it's complex system which are transforming external stimuli , like : Hot Cold -Pressure - sound - light
Is it possible for a composition reaction to also be a combustion reaction?
A composition reaction (sometimes also called a combination reaction.
Protein molecule that can speed up a chemical reaction?
That would be an enzyme. Also know as a biological Catalyst
What are the five ways to know that chemical reaction happened?
don't know
If a chemical reaction forms a single product from more than one reactant the reaction is?
a synthesis reaction, also called a combination reaction.
Is oxidation reaction a single replacement reaction?
It can be, but it can also be other types of reaction. An example of an oxidation reaction that is also a single replacement would be Zn(s) + 2HCl ==> ZnCl2 + H2. In this reaction Zn is oxidized and H is reduced.
What were medieval reaction to crucdifiction?
I dont know

What is the dark reaction of photosynthesis also nown as?
The light independent reaction.
What is a chemical change also referred to as?
Chemical reaction
What must you know about a nuclear reaction to calculate the amount of energy it will produce answers apex?
To calculate the amount of energy produced in a nuclear reaction, you need to know the type of reaction (fission or fusion) and the mass difference between the reactants and products. This mass difference can be used in Einstein's famous equation, E=mc^2, to determine the energy released during the reaction. Additionally, the binding energy per nucleon of the nuclei involved is also crucial in estimating the energy output of a nuclear reaction.
When magnesium ribbon is ignited it gives off a white fume of magnesium oxide. What is this type of reaction?
The reaction is 2Mg + O2 ----> 2MgO Mainly it is a Composition reaction (also called as combination or syntesis reaction). But also catogrised in redox reaction & combution reaction.
