Several properties of zinc (Zn) are listed below. 1. Malleable between 100° Cand 150° C 2. Bluish-white in color 3. Burns in air at high temperatures, giving off zinc oxide (Zno) gas 4. Conducts heat and electricity 5. Reacts with acids and bases Which statements describe only physical properties of zinc?​

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
