Answer:
1:C as all metal are good conductors of heat & electricity
2:D conductivity as it needs delocalized electrons normaly
3:B good conductors of heat & electricity
Answer:
82.04g
Explanation:
To solve this problem, you need to find the molar mass of HCl, which is the sum of the molar mass of H plus the molar mass of Cl. The molar mass of H is 1.008g/mol while the molar mass of Cl is 35.45g/mol. Thusly the molar mass of HCl is 36.458g/mol. You have 2.25 moles of HCl, so multiply the number of moles by the molar mass to get the mass in g. In this case it is 2.25mol * 36.458g/mol = 82.04g.
If I helped, a brainliest would be greatly appreciated!
