n=PV/RT
convert:
740 torr to atm (1 atm=760 torr)
50 degree celsius to kelvin ( degree celsus +273= kelvin)
n=(0.9737 atm)(12.5L)÷(0.08206 L atm mol ⁻¹k⁻¹) (323 K)
n=0.4592 mols×22.4 L/1 mol. (22.4 L STP= 1 mol)
=10.286 L at STP
it could be this
Answer: 8, which is basic
Explanation: The hydrogen ion concentration is 1.0 x 10^-8 mole per liter. Using [H+] = 1.0 x 10 -(pH) the pH is 8. A pH above 7 is basic.
Answer:
it depends on the medium and the temperature
Explanation:
D) Sulphur
Sulphur has the strongest electromagnetivity here
