The thiocyanate polyatomic ion, scn-, is commanly called a pseudohalogen because it acts very much like halide ions. for example, we know that pure halogens consists of diatiomic molecules, such as c12. thiocanate ions form similar molecules in the following reaction2nascn +2h2so4 + mno2 -> (scn)2 + 2h2o + mnso4 + na2so4a) write a conversion factor that could be used to convert between moles of nascn and moles of (scn)2b) how many moles of (scn)2 form when 0.05 moles of nascn react completely? c) what is the maximum number of moles of (scn)2 that could form in the combination of 4 moles of nascn and 3 moles of mnso4? d) write a convertion factor that could be used to convert between moles of sulfuric acid, h2so4 and moles manganese (ii) sulfate, mnso4.e) what is the minimum number of moles of h2so4 that must react to form 1.7752 moles of manganese (ii) sulfate?

A)

B) 0.025 mol (SCN)₂

C) 2 mol (SCN)₂

D)

E) 3.5504 mol H₂SO₄

Explanation:

2NaSCN +2H₂SO₄ + MnO₂ → (SCN)₂ + 2H₂O + MnSO₄ + Na₂SO₄

A) A conversion factor could be , as it has the units that we want to convert to in the numerator, and the units that we want to convert from in the denominator.

B) 0.05 mol NaSCN *   = 0.025 mol (SCN)₂

C) With 4 moles of NaSCN and 3 moles of MnSO₄, the reactant is NaSCN so we use that value to calculate the moles of product formed:

4 mol NaSCN * = 2 mol (SCN)₂

D)

E) 1.7752 mol MnSO₄ * = 3.5504 mol H₂SO₄

that's just how they are

explanation:

you can't control another persons decisions, all you can do is ask that they respect yours. relationships are hard because you have to put the effort into making sure that another person feels seen, heard, and loved. as time goes on, it gets easier, you learn how to do these things without thinking. loving them becomes as easy as breathing, but every relationship will have fights, and sometimes it'll feel like you're drowning, but as long as you can talk it out and compromise, because that's truly what loving another person is, is compromise, then you'll be okay. movies and tv shows have glamorized and romanticized (pardon the pun) what a relationship would be like. real relationships aren't perfectly timed kisses in the rain, zero fights until one big one ends everything, 6 month anniversaries. real relationships are sleepy confused kisses when one person has to leave for work earlier than the other,   real relationships are having small disagreements, real relationships are messy and confusing, real relationships is knowing that even if you're relationship may not last forever and this may not be the person you're going to spend the rest of your life with, that you love them, and you would do anything to see them happy. so yes, relationships are difficult, but so are many other things, relationships can be amazing but also stressful, and not just romantic i'm also talking about platonic relationships (although the primary example here was romantic) sometimes is best to leave friendships behind, so remember, always do whats going to you be happy in the long run.
