Answer;
-Copper (Cu)
Explanation;
-While all metals can conduct electricity, certain metals are more commonly used due to being highly conductive. The most common example is Copper. It is highly conductive which is why it is has been used in electrical wiring.
-Copper is used for electrical wiring because it is a good conductor of electricity. Metal particles are held together by strong metallic bonds, which is why they have high melting and boiling points. The free electrons in metals can move through the metal, allowing metals to conduct electricity.
the balanced equation for formation of potassium oxide is as follows
4K + O₂ --> 2K₂O
molar ratio of K to K₂O is 4:2
when 4 mol of potassium reacts, 2 mol of potassium oxide is formed
when 4 mol of K reacts - 2 mol of K₂O
when 1.52 mol of K reacts - 2/4 x 1.52 = 0.76 mol of K₂O
0.76 mol of K₂O is formed
I need to find the x pls help and show work 73838
H2SO4 ---> 2H^+ + SO4^2-
Hence n H+ = 9 mols
Mass of H = nM = (9*1) = 9g
Alternately
mass of H2SO4= nM= 4.5*98= 441
Mass of H= mass h2so4 * molar mass of H/molar mass of h2so4
Mass of H= 441 * 2/98 = 9g
