A gas has a volume of 45.0 mL and a pressure of .98 atm. If the pressure increased to 2.1 atm and the temperature remained the s
goblinko [34]

Answer: The new volume is 95.45 mL.

Explanation:

Given: V_{1} = 45.0 mL,         P_{1} = 0.98 atm

P_{2} = 2.1 atm,               V_{2} = ?

According to Boyle's law, at constant temperature the pressure of a gas is inversely proportional to its volume.

Therefore, formula used to calculate the new volume is as follows.

\frac{P_{1}}{V_{1}} = \frac{P_{2}}{V_{2}}

Substitute the values into above formula as follows.

\frac{P_{1}}{V_{1}} = \frac{P_{2}}{V_{2}}\\\frac{0.98 atm}{45.0 mL} = \frac{2.1 atm}{V_{2}}\\V_{2} = 95.45 mL

Thus, we can conclude that the new volume is 95.45 mL.

Which of these elements could gain one electron to form an ionic bond with potassium explain why
Svet_ta [14]

Answer:

<h3>Chlorine </h3>

It has 7 electrons in it last shell. it will gain one electron to complete its octet and become Cl-. The ionic bond of chlorine form with potassium is Kcl ( potassium chloride)

  • Phosphorus has 5 electrons in its last shell it need 3 more electron to stable .

  • Sulphur has 6 electron. it needs 2 electrons

  • Argon is already stable as it has 8 electrons in its last shell it will not gain or loose any electrons
