Using the pictures above, a solid material is dropped into a buret with an initial volume of liquid as indicated by the picture in the middle. The solid raises the level of the liquid in the buret to the reading shown by the picture on the right. If the solid has a mass of 14.225 g, what is the density of the solid?

Ch4 is nonpolar and insoluble in water. since all of the hydrogen atoms are evenly spread around the carbon atom even through the c h bond is polar all the poles cancel each other out.

They are all full and don't need any more electrons in there outer shell.

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
