There are two valence electrons in a single atom of magnesium.
Answer: -
Kinetic energy.
Explanation: -
Solids have the least kinetic energy and the highest intermolecular force of attraction among the three states of matter.
When heat energy is supplied to the solid, the kinetic energy of the solid particles increases. At some point, the kinetic energy becomes comparable to the intermolecular force of attraction. At that point solids change into liquids.
When further heat energy is given, at certain point the kinetic energy becomes far greater than the intermolecular forces of attraction. At that point it becomes gas.
Answer:
49.1 g
Explanation:
First we <u>convert 9.67x10²³ atoms of oxygen into moles</u>, using <em>Avogadro's number</em>:
- 9.67x10²³ atoms ÷ 6.023x10²³ atoms/mol = 1.60 mol O
Then we <u>calculate how many P₃O₉ moles there would be with 1.60 O moles</u>:
- 1.60 mol O *
= 0.18 mol P₃O₉
Finally we convert 0.18 P₃O₉ moles into grams, using its molar mass:
- 0.18 mol P₃O₉ * 237 g/mol = 49.1 g
Answer:
The English and French versions of the list of ingredients must begin on a separate line, except, for small packages with an available display surface (ADS) of less than 100 cm 2, where the second language version of the list of ingredients may start after the end of the first language list [B.01.008.2(9), FDR].
