It would be at 1 i believe because the heat you add after 0 degrees is then absorbed as potential energy instead of kinetic
Answer:
False
Explanation:
The temperature at which a solid melts, known as its melting point is highly characteristic of a compound and element.
The melting point of pure substances, compounds and elements is definite and not varied.
- Melting point is an intensive property of matter.
- It does not depend on the amount of matter present.
- It is an innate or intrinsic property of every matter.
- For example, no matter the volume or mass of water, it will always boil at 100°C, all things being equal.
Therefore, melting point of most solids is characteristic of compounds and elements.
Molar mass of N = 14 g/molMolar mass of O2 = 32 g/molAdding both masses = 46 g/molActual molar mass/ Empirical molar mass = 138.02 / 46 = 3Now multiplying this co effecient with empirical fomula NO2 = 3(NO2) = N3O6So according to above explanation,D) N3O6, is the correct answer.
The H-atom has fourth energy level with n=4.
This
energy level can have values of orbital angular momentum l = 0, 1, 2, 3
Now each l can also have magnetic momentum ml from – l to l.
Therefore,
l = 0
<span>ml = 0 </span>
l = 1
ml = -1, 0, 1
l = 2
ml = -2, -1, 0, 1, 2
l = 3
ml = -3, -2, -1, 0, 1, 2, 3
Now adding up all the number of ml’s will give us the total
number of orbitals:
orbitals = 1 + 3 + 5 + 7
orbitals = 16
Alternatively, we can simply use the formula:
<span>orbitals = n^2 = 4^2 = 16</span>
Answer : Option A) The body breaks down the molecules into molecules they need.
Explanation : Nutrient molecules are important because the body breaks the nutrient molecules and convert it into the absorb-able molecule that can generate energy for doing the activities of the body.
Nutrients are taken in the body in the form of carbohydrates which later on gets broken into glucose molecules and generates energy, proteins which is decomposed into amino acids, fats breaks down into fatty acids, minerals and salts are also nutrients which is essential nutrient for body.
