Explanation:
Answer:
covalent bond
Explanation:
a covalent bond happens between two nonmetals
a ionic bond happens between a metal and a non metal
CO2 is a bond between carbon and oxygen
carbon and oxygen are both non metals therefore CO2 is a covalent bond
The period is the end of the sentence!!!
Answer:
Explanation:
This is a direct application of the equation for ideal gases.
Where:
- P = pressure = 1.25 atm
- V = volume = 25.2 liter
- R = Universal constant of gases = 0.08206 atm-liter/K-mol
- T = absolute temperature = 25.0ºC = 25 + 273.15 K = 298.15 K
- n = number of moles
Solving for n:
Substituting:
MgCl2 because it is the only option in which a metal appears with a nonmetal. In this case, the metal transfers electrons to the nonmental because the metal has a lower ionization energy.
