Answer:
Explanation:
So, the formula for the compound should be:

Now we assume that we have 1 mol of substance, so we can make calculations to know the molar mass of element X, as follows:

So we have that 6 moles weight 212.7g, and we can make a rule of three to know the weight of compound X:

As we used 1 mol, we know that the molar mass is 32.06g/mol
So the element has a molar mass of 32.06 g/mol and an oxidation state of +6, with this information, we can assure that the element X is sulfur, so the compound is 
Thomson suggested the model of atom which was a sphere of positive matter within which electronic forces determined the positioning of the corpuscles. The corpuscles were distributed in a uniform sea of positive charge. This was so-called "plum pudding" model.
Answer: C ) Thomson
Answer:
Pioneer species I believe.
Explanation:
The name is heptane. The prefix is hept- , because the longest carbon chain contains seven carbons. The suffix is -ane, because this is the suffix used for all alkanes.

Answer:
No, these sample could no be same
Explanation:
Percentage of copper in both sample are different means both are taken from different sample because if we says both are from same sample then its violates the law of definite proportion
according to this law a given compound always contains same proportion of element by mass and it does not depend on the source
eg: water from sea and drainage both have same composition means same amount of oxygen and hydrogen by mass is present
Hence given samples are not same
