Which equation represents a nuclear reaction that an example of an artificial transmutation?
1) 43/21 sc--> 43/20 ca + 0/+1 e
2) 14/7 n + 4/2 he --> 17/8 o + 1/1 h
3) 10/4be--> 10/5b+0/-1e
4) 14/6c--> 14/7n+0/-1e

Insoluble sulfide compounds are generally black in color. which of the following combinations could yield a black precipitate? check all that apply. na2s(aq)+kcl(aq) li2s(aq)+pb(no3)2(aq) pb(clo3)2(aq)+nano3(aq) agno3(aq)+kcl(aq) k2s(aq)+sn(no3)4(aq)

What is the average rate of the reaction between 10 and 20 s?

2-bromo-2-methylbutane undergoes an e1 elimination reaction in the presence of ethanol. in the next reaction only one of the possible products is represented. although the product shown is not the major product of the reaction, notice that there is more than one way it can be produced. complete the mechanism and draw the missing substances.
