Answer:
Nitrates.
Explanation:
They convert ammonia to nitrates.
Explanation:
Intermolecular force s between particles in a matter holds particles of molecules together in substances.
- The stronger the intermolecular forces the more solid a substance is.
- The weakest intermolecular attraction are found in gases as they have negligible attractive forces in between their particles.
- Solids are held together by very strong attractive forces.
- Liquids have weak forces holding them in place and this allows for a little movement.
- Gases are typically have very weak to negligible attractive forces.
Answer:
C. +5
Explanation:
Oxygen is always -2. And the sum of the oxidation numbers must be equal to the charge. So:
2x + 7(-2) = -4
2x - 14 = -4
2x = 10
x=5
Answer:
True
Explanation:
<u>The first law of thermodynamics</u> establishes a relationship between the internal energy of the system and the energy that it exchanges with the environment in the form of heat or work.
The first law of thermodynamics determines that the internal energy of a system increases when heat is transferred or work is done on it.
Like all the principles of thermodynamics, the first principle is based on systems in equilibrium.
On the other hand, it is likely that you have heard more than once that energy is neither created nor destroyed, only transformed. It is the general principle of energy conservation. Well, the first law of thermodynamics is the application to thermal processes of this principle.
The universe as a whole could be considered an isolated system, and therefore its total energy remains constant.
