The temperature : 154.73 K
<h3>Further explanation</h3>
Given
mass = m = 5 g of Cl2
P = 900 mmHg = 1,18421 atm
V = 0.75 L
Required
Temperature
Solution
mol Cl2 = mass : MW = 5 : 71 = 0.07
Ideal gas law : PV = nRT
P = pressure, atm
V = volume, liter
n = number of moles
R = gas constant = 0.082 L.atm / mol K
T = temperature, Kelvin
T = PV/nR
Input the value :
T = 1.18421 x 0.75 / 0.07 x 0.082
T = 154.73 K
Answer:
The object will not be in motion
Explanation:
An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force. ... Objects resist changes in their velocity.
Answer:
The energy of photon is 20.22×10⁻¹⁷ J
Explanation:
Given data:
Frequency of photon = 3.05×10¹⁷ Hz
Energy of photon = ?
Solution:
Formula:
E = hf
h = planck's constant = 6.63×10⁻³⁴ Js
Now we will put the values in formula.
E = 6.63×10⁻³⁴ Js × 3.05×10¹⁷ Hz
Hz = s⁻¹
E = 20.22×10⁻¹⁷ J
Thus, the energy of photon is 20.22×10⁻¹⁷ J
Answer:
Explanation:
Hello there!
In this case, since the ionization of benzoic acid is:
Whereas the corresponding equilibrium expression is:
Now, we insert the acidic equilibrium constant and the reaction extent x, to write:
Thus, by solving for x, we obtain:
Which is also:
