maybe 1+8 (4+548) 4/6 4+4
Answer:
28.28 L.
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.</em>
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If n and T are constant, and have two different values of V and P:
<em>P₁V₁ = P₂V₂</em>
<em></em>
P₁ = 700.0 mm Hg, V₁ = 4.0 L.
at burst: P₂ = 99.0 mm Hg, V₂ = ??? L.
<em>∴ V₂ = P₁V₁/P₂</em> = (700.0 mm Hg)(4.0 L)/(99.0 mm Hg) = <em>28.28 L.</em>

Explanation:
Ionic crystals
1. They are formed by electrostatic attraction between the cation and anion.
2. Naturally solid and brittle in nature.
3.Generally good conductors of electricity in moltane state and have high melting and boiling points.
Example: NH4Cl is an inonic compound with NH4^+ being cation and Cl- being anion.
Molecular Solid
1. These are formed by sharing of electrons pair between the atoms. A shared pair of e- is called a covalent bond.
2. Usually not a good conductor of electricity even in melted state.
3. They mostly liquids and gases only a few are solids.
examples , CO, CO2 , H2CO3 , etc.
