the reaction must occur without energy. I.e. the rolling of a ball down a hill

If dissolving calcium chloride in water is spontaneous what is the sign?
If dissolving calcium chloride in water is spontaneous, the sign of ΔG (Gibbs free energy) is negative.
Oxygen in air causes iron to rust so iron and oxygen are what in this process?
a process called Oxidation
The burning of charcoal is a spontaneous process yet heat must first be applied to start a charcoal why?
Burning charcoal is spontaneous, but not at room temperature. To start the combustion energy must be added (in the form of heat). Once the temperature of the charcoal reaches a certain temperature it reacts exothermically and releases heat. This heat of reaction is sufficient to locally heat more charcoal so that it burns continuously.
What is the theory of Spontaneous Reproduction?
spontaneous reproduction is when out of no where, something is reproduced. many, many, years ago, people didn't have refrigerators to keep their food fresh. so their meat and other foods would spoil and so there would be magots and other insects crawling in their food. their explanation would be spontaneous reproduction.(they thought dead meat could reproduce living organisms)
Why LDAP is called lightweight?
the ldap is independent of other process & it self as a thread and not use OS memory so its called lightweight
Is it criteria are or criteria is if there is more than one criteria?
The correct term is "criteria are" when referring to multiple criteria. "Criteria" is the plural form of "criterion," so it should always be treated as a plural noun in a sentence.
If dissolving calcium chloride in water is spontaneous what is the sign?
If dissolving calcium chloride in water is spontaneous, the sign of ΔG (Gibbs free energy) is negative.
How If a reaction occurs at 293 K that has a change in enthalpy of plus 125 kJ and a change in entropy of plus 35 J K then is the reaction spontaneous If so why If not why not?
A process will be spontaneous when the change in Gibbs free energy is negative.The change in Gibbs free energy can be calculated from the equation:G2 - G1 = H2 - H1 - T(S2 - S1)whereG is Gibbs free energyH is EnthalpyT is absolute temperature (when T is given in Kelvin or Rankine it is an absolute temperature)S is EntropyIn this caseH2 - H1 = 125 kJT = 293 KS2 - S1 = 35 J/K = 0.035 kJ/Kso doing the math you getG2 - G1 = 125 - 293(0.35) = 22.45 > 0 so the process is not spontaneous in the direction where enthalpy change and entropy change are being measured. The reverse process would be spontaneous.
What does rehearsed improvisation mean in drama?
Rehearsed improvisation is when you've made something up from the spot but repeated it many times so that it is perfected. Basically you rehearse the spontaneous improvisation that you made up. But because you've rehearsed it many times, it is no longer called 'spontaneous' but 'rehearsed'.
What group process is this called?
It would be easy to answer your question if it was complete. What is this process called ? seems to be an incomplete question. Which process you are talking about? There are many processes in this world of Biology.
How does the water move into the atmosphere?
It does so by the process called evaporation.
What can be said about a reaction with H 620 kJmol and S -0.46 kJ molK?
it can never be spontanious
Oxygen in air causes iron to rust so iron and oxygen are what in this process?
a process called Oxidation
Is respiration spontaneous?
Yes, spontaneous basically means by itself or you do it without noticing, so respiration or breathing is something we do without knowing like when we're sleeping.
Single word of criteria?
I take it you mean 'What is the singular form of the word criteria?' If so, the answer is criterion.
What is the difference between product audit and process audit in automotive industry?
Product audit are audit for product itself. Criteria product, how to know the product, what is special identification an so on. Process audit are audit to the process to produce the part from incoming material to part become finish goods...
Can AND criteria determine fields selected for a query?
Criteria determine what records can be shown, not what fields can be shown, so the AND criteria cannot be used to determine what fields to select.
