What is the molarity of a potassium triiodide solution, ki3(aq), if 30.00 ml of the solution is required to completely react with 25.00 ml of a 0.300 m thiosulfate solution, k2s2o3(aq)? the chemical equation for the reaction is 2 s2o32-(aq) + i3-(aq) → s4o62-(aq) + 3 i-(aq).
i believe the answer would be c
the the compound of interest i.e. xcl4, since there are 4 cl atoms bonded to x. this signifies that the valency of x is 4.
there atomic number of c is 6. it's electronic configuration is giving by 1s2 2s2 2p2. thus, there are 4 electrons in valence shell of c. this signifies that valency of c is 4. hence the compound present in present case is ccl4.
hope this : )
(74/3)+(81/5)=40.8666666666666/2=20.4333333333 so the answer is 20.4333333333
the ionosphere is a layer of the earth's atmosphere that is weakly ionized, and thus conducts electricity . it is located approximately in the same region as the top half of the mesosphere and the entire thermosphere in the upper atmosphere, from about 40 mi (60 km), continuing upward to the magnetosphere.
the correct answer should be:
~d. strong acid.
