Those answers are right. I also got 100% :-)

**Chemistry**

The energy level of the valence electrons of every element is the same as its period in the periodic table. So in this case Lead = 6 (E.)

**math**

m^8n^6 _______ m^4n^2 i got m^2n^3. is this right? Is this a division problem? If so, you subtract exponents. a^4/a= a^3

**math**

9c^5d^8 * 4c^5d^8 __________________ 2c^5d^5 the answer i got is 18d^21c^15 is this anywhere close to being right? :) pls show how you get the answer if its different! :) thx Is this problem division, or multiplication? Either way, it is wrong.
