Answer:
The answer to your question is:
Explanation:
a)
Metals: are shiny, malleable and ductile, they can conduct electricity and heat, form cations in aqueous solutions.
Nonmetals: non-lustrous, brittle, not good conductors of heat and electricity, form anions in aqueous solutions.
b)
Metals are located in the left side of the periodic table
Nonmetals are located in the right side of the periodic table.
c)
Metal are use to make pans because they are good conductors of heat and also are malleable and ductile.
Nonmetals are used to make sleeping bags and coolers because they do not conduct heat so they can isolate matter.
The answer is B hope this helped
The mass of hydrogen atoms that is measured at 54 u given the relationship is 89.64×10¯²⁴ g
<h3>Conversion scale </h3>
1 u = 1.66×10¯²⁴ g
<h3>How to determine the mass of hydrogen atoms </h3>
- Mass of Hydrogen (u) = 54 u
- Mass of Hydrogen (g) =?
1 u = 1.66×10¯²⁴ g
Therefore
54 u = 54 × 1.66×10¯²⁴ g
54 u = 89.64×10¯²⁴ g
Thus, the mass of the hydrogen atoms measured at 54 u is 89.64×10¯²⁴ g
