L'air n'est pas un mélange gazeux, donc la réponse serait le verre
Answer:
Ingredient lists and nutritional facts
Explanation:
The packaged food, a consumer purchases has all its details written on the food package which is also verified by a trusted government institution.
The list tells each ingredient in food product by the food's common or usual name in the descending order by the weight.
- <u>Nutrition Facts Label
</u>
FDA requires this label on most of the packaged foods and the beverages. At top of Nutrition Facts label, there is written total number of the servings in container and serving size of food or drink. Serving size on label is based on amount of the food which people eat typically at one time. Rest of nutrition information on label is based usually on one serving of food or beverage.
Answer:
178.1g
Explanation:
m= n × MM
where
m is mass
n is moles &
MM is molecular mass
The molecular mass of cobalt is 58.933195. With this information and the number of moles given in the question, we can perform the calculation
m= 3.022 × 58.933195
m=178.09611529
m= 178.1g
Answer: The transition elements are in the d-block, and in the d-orbital have valence electrons. They can form several states of oxidation and contain different ions. Inner transition elements are in the f-block, and in the f-orbital have valence electrons.
Explanation:
Explanation:
Noble gas configuration is defined as the configuration which contains completely filled orbitals.
For example, oxygen atom when gain two electrons then it forms oxygen ion (
).
Atomic number of oxygen atom is 8 and so, its number of electrons will also be 8. But when it gain two electrons then it has total 10 electrons. Hence, electronic configuration of is as follows.
Since, there are completely filled orbitals in an ions. Therefore, it means this ion has a noble-gas configuration.
Thus, we can conclude that any specie which shows completely filled orbitals will have noble-gas configuration.
