Answer:
the quantity of solution to moles for d is significantly lower.
Explanation:
the larger the amount of liquid, the less amount of ions to dissociate hence having a lesser amount of chloride ions.
compared to b which is less liquid and a higher concentration
Answer:
The correct answer is C. element
Explanation:
The sample cannot be an element because an element - or <em>elemental substance</em> - cannot be decomposed into simpler substances. Thus, it cannot be composed by differents types of atoms. For example, an element is carbon (C).
As the sample contains <u>three types of atoms</u>, it can be a compound, a molecule or a mixture, because they can be composed by different types of atoms - of different chemical elements. For example, the sample could contain the element carbon (C) combined with other elements, for example oxygen (O) or hydrogen (H), amoing others.
Because they can look at the fossils that they left behind and see what kind of animal it was and what happened to it if another animal is inside of the fossil or if the bones are misplaced
Answer: There are 0.499 moles present in 
molecules of Boron trichloride.
Explanation:
According to mole concept, there are 
molecules present in 1 mole of a substance.
Hence, number of moles present in molecules are as follows.
Thus, we can conclude that there are 0.499 moles present in molecules of Boron trichloride.
Each column is called a group<span>. The elements in each </span>group have<span> the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons.</span>
