Answer: Three groups bound to it with no lone pairs
i think...
Because area of the container has increased , there will be fewer of collisions per unit area and the pressure will decrease . Volume is inversely proportional to pressure , if the number of particles and temperature is constant
( V = 1/P) and number of particle is proportional to pressure if average Kinetic energy of the particle remain same , the average force particle will remain same too so at some places and there will be more collision and there is greater pressure
We calculate the molar concentration [Cl⁻] using stoichiometry. MnCl2(aq) is an ionic compound which will have the releasing of 2 Cl⁻ ions ions in water for every molecule of MnCl2 that dissolves.
MnCl2(s) --> Mn+(aq) + 2 Cl⁻(aq)
[Cl⁻] = 0.68 mol MnCl2/1L × 2 mol Cl⁻ / 1 mol MnCl2 = 1.4 M
The answer to this question is [Cl⁻] = 1.4 M
<u>Answer:</u> The temperature in degree Celsius is 301.31°C
<u>Explanation:</u>
To calculate the temperature, we use the equation given by ideal gas, which is:
P = pressure of the gas = 670 torr = 0.882 atm (Conversion factor: 1 atm = 760 torr)
V = volume of gas = 42.5 L
n = number of moles of gas = 0.795 mol
R = Gas constant = 
T = temperature of gas
Putting values in above equation, we get:
Converting the temperature from kelvins to degree Celsius, by using the conversion factor:
Hence, the temperature in degree Celsius is 301.31°C
