Answer:
About 1.301 atm
Explanation:
The formula that you should is PV=nRT, where P stands for pressure, V stands for volume, n stands for the number of moles, R stands for the universal gas constant, and T stands for temperature in Kelvin. Since the volume, number of moles, and universal gas constant don't change, you don't need to worry about them.
1.07V=393nR
PV=498nR
P=1.301 atm. Hope this helps!
Mass/volume cause you divide to get density
Answer:
Explanation:
mass of aluminum 2.8 kg = 2.8 x 1000 = 2800 g
ρ = density of aluminum given = 2.7 g / cm³
density = mass / volume
volume = mass / density
= 2800 / 2.7
= 1037 cm³
So volume of cube required = 1037 cm³.
The correct answer is 1) Ag, Si, I₂
Ag or silver is a metal. Silver is a transition element which lies in the d-block of the periodic table.
Si or silicon is a metalloid. Silicon is a metalloid which lies in the p-block of the periodic table.
I₂ or iodine is a nonmetal. Iodine is a halogen which lies in group 17 of the periodic table. All halogens are nonmetals.
