Sonya is studying a nonmetal element. she learns that the element is like other elements in its group because it can bond to form a salt or an acid. she also learns that the element is the most reactive element in its group. which element is sonya most likely studying?

answer; ///i do believe that the correct answer is (b); ///particle composed of two or more atoms bonded together;

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles
