Explain how wood burning in a fire place undergoes a chemical change?
Burning is an oxydation reaction so a chemical change.
Explain How evaporative cooling leads to a reduction in body temperature?
Evaporative cooling in mammals is essentially done by through, using body heat to heat up the sweat (moisture to gas) and once the sweat evaporates, the heat taken away with it.
It is possible to explain the ion any given atom is likely to form If so explain?
Look at periodic table (see link). Left side gives up electrons (positive ions) Right side collects electrons (negative ions) (Except far right - no reaction, no ions)
What effects does water have on the body?
The list of the bodies uses for water is to long to explain. It is used in energy production. Cell growth. Transfer of electrical signals. Almost all chemical processes in the body at somepoint have a reaction with water.
How do you use the word explain in a sentence?
Give me a chance to explain what happened.If you're confused, I'll explain the directions again.When he took the stand, the defendant tried to explain the reason for his actions.
What is the difference between an exothermic and an endothermic chemical reaction?
Nothing to explain; that is the way EXO- and ENDOthemic reactions are called by definition
Is breathing an endothermic or exothermic reaction?
Breathing is an exothermic reaction. To explain clearly, during digestion food particles break down into smaller particles. These turn into glucose, this glucose combines with the oxygen present in the cell and provides energy. The special name of this reaction is respiration. It releases heat so it is an exothermic reaction.
Is the process of celular respiration exothemic or endothermic explain your answer?
exothermic
Explain Why a reaction is exothermic or endothermic because of bond energies?
the reaction is OH ç CH3 CH = CH CH2 CH3 + 2 H2O ® CH3 CH CH CH2 CH3 ç OH
In an endothermic reaction are the products more or less stable than the reactants and explain your answer?
The products of an endothermic reaction are less chemically stable. They required an input of energy to create so naturally they are at a higher energy state.
Is evaporation an exothermic or endothermic process explain?
It will be an endothermic process because the beaker becomes cool after evaporation.
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 energy from the system. In an endothermic reaction a thermometer measuring the reactants and products would register a decrease in temperature.
What do understand by glass transition temperature. Explain whether it is exothermic or endothermic?
glass transition is a change in state. when the state changes from crystalline or rather glassy to a rubbery like state. it should be noted that it is not melting. it is a state change and not a phase change. it is endothermic phenomena because heat is given to a system so that glass transition occurs. because no heat is released during the process it can not be considered to be endothermic.
You may normally expect a slow reaction if a low activation energy is required?
Explain why a high energy of activation causes a reaction to be slow?
Chemistry model questions of plus one?
What is the atomic number and mass number of an atom with 12 protons and 14 neutrons? Explain the difference between an element and a compound. How many valence electrons are there in an atom of chlorine? What is the difference between an exothermic and endothermic reaction? Define the terms solute and solvent and give an example of a solute-solvent mixture in everyday life.
Can combination reaction be oxidation reaction Explain?
No
Explain why the theoretical lattice energies become less exothermic from AgF to AgI?
YES
