Can delta s be negative Entropy?
yes
When a number is positive?
A positive number is any number above zero. A negative number is any number below zero. Zero is not a positive or a negative number. A number's opposite is just the negative. For example: 8's opposite is -8 (negative 8). Hope this helped!
How can you have a negative headwind?
In athletics a headwind is expressed in negative terms eg - 5 m/s a wind in your face of 5 metres per second. A tailwind is expressed in positive terms eg + 5 m/s. The positive & negative seem superfluous as a headwind and tailwind are self explanatory
What is the difference of positive and negative?
Postib=ve i s biger and negative are they same but there a postive n a negetive side and th neg are sometimes biger
What is your acceleration if you travel 50 meters in 30 seconds at a constant speed?
Meed velocity first. V = delta X/delta t V = 50 m/30 s = 1.666 m/s now, acceleration A = delta V/delta t A = 1.666 m/s/30 s = 0.056 m/s2 ============
What conditions make delta G always positive?
G is always positive when enthalpy increases and entropy decreases.
Is the process of KNO3 dissolving in water spontaneous at all temperatures studied?
yes delta s is positive, delta h is negative making delta g negative at all temps
How will temperature affect the spontaneity of a reaction positive delta h and delta s?
∆G = ∆H - T∆S and for it to be spontaneous, ∆G should be negative. If both ∆H and ∆S are positive, in order to get a negative ∆H, the temperature needs to be elevated in order to make the ∆S term greater than the ∆H term. So, I guess the answer would be "the higher the temperature, the more likely will be the spontaneity of the reaction."
Can delta s be negative Entropy?
yes
Is S epidermidis gram negative or gram positive?
gram positive..
What conditions make G always negative?
G is always negative when H is negative and S is positive.
How do you predict delta s?
delta s (change in entropy) is positive when.... -you go from a solid to a liquid -you go from a liquid to a gas -when you go from a solid to a gas -when there are more mols of products than mols of reactant the change in entropy is negative when the reverse of the above happens
What determine whether a reaction took place?
Use the following equation: delta G = delta H - T*deltaS. A reaction is spontaneous if delta G is negative. A reaction will always be spontaneous (under any temperature) only if the change in enthalpy (delta H) is negative and the change in entropy (delta S) is positive. If this is not the case, the reaction will only be spontaneous (negative delta G) for a range of temperatures (or could be always non-spontaneous)
A chemical reaction that has a positive ΔG is correctly described as?
This is a nonspontaneous reaction, which means that it is reactant-favored. According to the second law of thermodynamics, product-favored reactions must have a negative delta G.It can also be described as an endergonic reaction - that is a chemical reaction in which the standard change in free energy is positive, and energy is absorbed.
What condition is G for a reaction always positive?
When H and S are both positive
Is prime number positive or negative number?
Its a positive number(s)
Under what conditions is G for a reaction always positive?
When H is positive and S is negative
