I'd say that it will shift to the left because HCl will provide additional H+ ions which are present on the right side of the equation. Higher concentration of reagents on the one side - chemical equilibrium moves to the opposite side (le chatelier's principle)

How is primary selection different from secondary succession?
PIT_PIT [208]

Answer:

Explanation:

Primary and secondary succession occur after both human and natural events that cause drastic change in the makeup of an area. Primary succession occurs in areas where there is no soil and secondary succession occurs in areas where there is soil.

In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area previously occupied by living things is disturbed—disrupted—then recolonized following the disturbance.

Hope this helped :)

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.

IS Typtophan an element on the periodic table?
denpristay [2]
No it is an amino acid present in the synthesis of certain proteins. Elements are pure substances so an acid (which is a compound of different elements) would not be considered an element.
