Is photosynthesis an exothermic or endothermic reaction?
Yes photosynthesis is a endergonic process i.e. energy-requiring process.
What is endothermic use in a sentence?
Endothermic means a temperature under a surface and is used in a number of instances, most notably medicine where it is used to describe a temperature under the skin, and geology where it can be used to describe the temperature under the suface of a planet, therefore a use of endothermic in a sentence could be;"The endothermic temperature of the planet was greater than that of it's surface."
Are endothermic reactions always nonspontaneous?
No, many exothermic reactions need the heat of activation to start the reaction. Paper, for instance, does not spontaneously burst into flame... you need to raise its temperature to the kindling point for it to burn.
Is boiling of water am endothermic or exothermic?
Yes boiling water is endothermic because you are supplying the energy to the water molecules. (Or in most instances the kettle is supplying the energy to the water, still endothermic), the water doesn't just spontaneously boil at 25C and release heat energy, it takes you putting in massive energy to get it to boil.
Is the melting of candle wax and exothermic or endothermic change?
The answer is endothermic. The wax is absorbing heat energy, not producing it, and changing from a solid state to a liquid state. If the reactants require more energy than than they are putting out during the reaction, it is said to be endothermic (absorbing of heat). If the reactants give off heat of their own (self sustaining), then it is an exothermic reaction. There are components in some types of wax that will burn, in which case that is an example of an exothermic reaction, but most wax will stop once the heat source is removed.
Is photosynthesis an exothermic or endothermic reaction?
Yes photosynthesis is a endergonic process i.e. energy-requiring process.
What is the type of chemical reaction in which heat energy is absorbed?
Endothermic reactions.Endo- means 'inside' which is where the energy ends up.Exothermic reactions give off energy. Exo- means 'outside'. Think that a spider sheds an 'exo'skeleton, or a skin on the outside.
Is the reaction between x which forms X2 exothermic or endothermic?
Most normally this 2X --> X2 reaction is exothermicbut it is not a general rule.
A chemical reaction that gives off heat is most likely to be what?
An endothermic reaction is one that consumes heat.
What is the worlds most important mammal?
a person
When your body metabolizes food is it endothermic?
No, in most cases it isn't endothermic. Metabolism, based on the Krebs Cycle, is a biochemical reaction which creates Adenosine Triphosphate, also known as ATP and Energy. Energy is in fact exothermic.
When ammonium chloride mixes with water the solution formed feels cold what type of reaction is this endothermic or exothermic?
When ammonium chloride dissolves in water, it is not a reaction at all, but only a dissolution. Since the solution formed feels cold, the dissolution is endothermic, absorbing heat from its surroundings.
Are all thermal decomposition reactions endothermic in nature?
Yes, but rather: 'most of all' combination reactions are exothermic. This is mostly true for spontaneous, common reactions.Examples of the contrary endothermic reactions, though rare, are:The formation reaction (= combination 'pur sang') of ethene, propene, acetylene, and even benzene is endothermic, when combined out of elements (that's why they are called endothermic compounds). Further a lot of metal hydride's, chlorous oxide: ClO2 are endothermic.The most Exceptional Endothermic Compound is:Dicyanoacetylene, IUPAC-name: but-2-ynedinitrile, C4N2 (or more structural: NC-CC-CN)Standard heat of formation Ho298 ( 4C + N2 --> ) is 500.4 kJ/molBecause of its high endothermic heat of formation, it can explode to carbon powder and nitrogen gas (reversed formation reaction, exo. 500.4 kJ/mol).It burns in oxygen with a bright blue-white flame at a temperature of 5260 K, which is probably the hottest flame of any chemical.
Why was Pope John Paul II important?
Because he was recognised as the worlds most religious leader
A chemical reaction that transfers energy from the reactants to the surroundings is reffered to as?
A chemical reaction that transfers energy from the reactants to the surroundings is referred to as an exothermic reaction. A reaction that takes energy in is endothermic.
What is an endothermic reaction in fireworks?
An endothermic reaction in fireworks occurs when certain chemical processes absorb heat from their surroundings, leading to a drop in temperature. While most fireworks produce exothermic reactions that release energy and heat, some components can undergo endothermic processes, such as the dissolution of certain salts or reactions that require energy input. These endothermic reactions can contribute to the overall effect and behavior of the firework, affecting its color and performance. However, they are less common compared to the predominant exothermic reactions that create the explosive effects and bright displays.
Can you name another compound whose dissolution will be endothermic?
Dissolution for most substances is endothermic.
