zaharov [31]

Answer:

$P_{He}^|=288.85torr$

Explanation:

Given data

$P_{He}=750 torr\\V_{He}=285mL\\P_{Ar}=732 torr\\V_{Ar}=455 mL$

Required

Partial pressure of helium

Solution

First calculate the total volume of gas mixture once the stopcock is opened

$V_{total}=V_{He}+V_{Ar}\\V_{total}=285mL+455mL\\V_{total}=740mL$

As temperature remains constant,by Boyle's Law we calculate the partial pressure of the helium gas

$P_{He}V_{He}=P_{He}^|V_{total}\\P_{He}^|=\frac{P_{He}V_{He}}{V_{total}}\\P_{He}^|=\frac{750torr*285mL}{740mL}\\ P_{He}^|=288.85torr$

3. Why does any bonding occur (this includes ionic bonding and covalent bonding)?

Rzqust [24]

Answer:im not sure but hope this helps

Explanation:

Covalent bonds are formed because of sharing electrons whereas ionic bonds formation occurs because of transferring of electrons. Molecules are the particles in covalent bonds all through compound formation whereas in ionic bonds these are positively charged and negatively charged ions.
