when 48 .0g of carbon reacts with oxygen gas to form carbon dioxide, no carbon or oxygen is left over. How much oxygen is reacte
Arte-miy333 [17]

Answer:

128g

Explanation:

Given parameters:

Mass of carbon  = 48g

Mass of carbon dioxide  = 176g

Unknown:

Mass of oxygen that reacted  = ?

Solution:

Every chemical reaction must obey the law of conservation of mass. It states that "in a chemical reaction, matter is neither created nor destroyed" .

So;

     Mass of carbon + Mass of oxygen  = Mass of carbon dioxide

Mass of oxygen  = Mass of carbon dioxide  - Mass of carbon

Mass of oxygen  = 176  - 48  = 128g

Which ion has the smallest radius?<br> (1) O2-<br> (2) S2-<br> (3) Se2-<br> (4) Te2-
podryga [215]

Answer:


                  Option-1 (O²⁻) is the correct answer.


Explanation:

                       All given anions contains same charge. So, we can ignore the effect of charge on these anions.


As we know all given compounds belongs to same group (Group 6) in periodic table. And from top to bottom along the group the elements are placed as,


                                                          Oxygen O


                                                          Sulfur S


                                                          Selenium Se


                                                          Tellurium Te


Hence, moving from top to bottom along the group the number of shells increases. And with increase in number of shell the atomic or ionic radii increases. As Oxygen is present at the top of the group, therefore, it has the smallest radius due to less number of shells.
