I would pick either b) or D) but you just have to remember that not all ionicbonds will bond together, because some bonds are only negattive bonds,
Answer:
Na and Cl
Explanation:
An ionic compound is solid at state room temperature. Therefore Na and Cl would be the correct answer :)
Answer:
because there more acid in diet cola
C)
Metallic solids consist of metal ions which are surrounded by delocalized electrons.
Answer:
n = 11.45 mol
Explanation:
Given data:
Number of moles = ?
Volume of gas = 98 L
Pressure = 2.8 atm
temperature = 292 K
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
2.8 atm × 98 L = n × 0.0821 atm.L/ mol.K × 292 K
274.4 atm.L = n × 23.97atm.L/ mol
n = 274.4 atm.L /23.97atm.L/ mol
n = 11.45 mol
