For exothermic processes, spontaneity will only occur if the entropy positive with all temperature or if the entropy is negative with only low temperature.
Since the given equation decomposed from 2 moles of gas into 3 moles of gas, we know that entropy is positive. Thus the reaction will be spontaneous at all temperature.
D is the answer
Answer:
Parallel Circuit
Explanation:
In a parallel circuit, there are multiple paths through which the current can flow, so the resistance of the overall circuit is lower than it would be if only one path was available.
Answer: A. It is made of polar molecules.
Explanation:
A polar molecule refers to a molecule that has a covalent bond but has an uneven distribution of electrons due to an atom in the molecule having strong electronegativity which will attract more of the electrons from the other atom.
Water is such a molecule because Oxygen has strong electronegativity which leads to electrons being pulled to it.
Mechanical energy is the sum of potential energy and kinetic energy present in the components of a mechanical system. It is the energy associated with the motion and position of an object. All energy can be expressed in Joules (including thermal <span>energy</span>
Write as a proportion, showing the relationship of both given information:
68.0g 0.3g
---------- = -----------
1L x ( your answer)
Cross multiply: 68.0g× X = 0.3g × 1L
68.0g (X)= 0.3g/L
Solve for X by dividing both sides by 68.0 g
68.0g (X) = 0.3g/L
------------- ------------------
68.0g 68.0g
Then enter into calculator 0.3/68 and that will be your solution. Make sure you round up.
