Mixture is physically combined and substance is chemically combined and can only be changed in identity and properties by chemical methods
Answer:
15.06 L
Explanation:
Using the ideal gas law equation:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
According to the information provided in this question,
P = 3.50 atm
n = 1.9 moles
V = ?
T = 65°C = 65 + 273 = 338K
Using PV = nRT
V = nRT/P
V = (1.9 × 0.0821 × 338) ÷ (3.5)
V = 52.725 ÷ 3.5
V = 15.06 L
The F is 2.980 x 104 N gravity Gm1 is 2523 kg m₂ is 5.68 x 1026 kg and radius 54,364 km and height is 108,728 km.
<h3>What is gravity?</h3>
Gravity is the amount of force that is produced by the earth to attract the object toward the surface and it doubles if the mass is double.
The height of Saturn is the duble of the radius of the given radius of 54,364 km of the planet Saturn which is 108,728 km.
Therefore, F is 2.980 x 104 N gravity Gm1 is 2523 kg m₂ is 5.68 x 1026 kg and radius 54,364 km and hight is 108,728 km.

Answer:</h3>
Ionic compounds
<h3>
Explanation:</h3>
What are ionic compounds?
- Ionic compounds are compounds that are formed due to ionic bonds between atoms.
- Ionic bonds are formed between metallic atoms and non-metallic atoms.
What are examples of ionic compounds?
- Examples of ionic compounds include, KCl, NaBr, MgCl₂, etc
How do ionic compound ionize in water?
- Ionic compounds ionizes when dissolved in water to form mobile ions.
- When dissolved in water they may serve as electrolytes due to the presence of free ions which will be responsible for conduction of electricity.
- For example, NaCl ionizes to form Na⁺(aq) and Cl⁻(aq).
