True
Explanation:
In the crystal of an ionic compound, the cations are surrounded by anions so that the charges of the ions are balanced. This very correct.
Ionic compounds are electrically neutral and forms by a charge balance.
- To form an ionic crystal, the charges overall must be balanced and the compound must remain electrically neutral.
- Equal number of charges on the metal and non-metal must cancel out to establish an electrostatic force.

Answer: 20 mol CH4 x 1CO2 / 1CH4 = 20mol CO2
Answer: 20mol CO2
Explanation:
Answer:
Π = 21.9 atm
Explanation:
The equation used to find osmotic pressure is:
Π = iMRT
In this formula,
>> Π = osmotic pressure (atm)
>> i = van't Hoff factor
>> M = molarity (M)
>> R = constant (0.0821 atm*L/mol*K)
>> T = temperature (K)
Remember, van't Hoff factor is the amount of ions the species (MgCl₂) dissociates into while in solution. MgCl₂ dissociates into 3 ions. These ions are Mg²⁺ and 2 Cl⁻.
The temperature needs to be in Kelvin....
37.0 °C + 273.15 = 310.15 K
You now know the value of all the variables.
Π = iMRT
Π = (3)(0.287 M)(0.0821 atm*L/mol*K)(310.15 K)
Π = 21.9 atm
Answer:
I not sure if this is right but maybe b since its particles is more spread out?
