Diborane can be made with the following unbalanced reaction: NaBH_(4(s))+I_(2(s))→B_2 H_(6(g))+NaI_((s))+ H_(2(g))

If 1.203g of NaBH4 are reacted with 7.050g of iodine, what is the theoretical yield of diborane in grams?
If you isolate 0.295g of diborane, what is your percent yield?

Adozen is 1221/12 = 1.751.75 x 12 = 21therefore, 1.75 is the answer.

It is 4.92 e-4 sorry if i am wrong

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .
