12. What is a metal on the periodic table? What is a nonmetal? (Relative to the metalloid staircase)

Metals are left of the Metalloid stair case and non metals are right

Explanation:

Pick any metal on the periodic table (left of the staircase). Aluminum, Calcium, Lead, anything but Hydrogen.

Non-metals are found on the right side of the staircase. Chorine, Iodine, Carbon, etc

**Keep in mind that not all solids are metalloids.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;
