Moles of NaCl
Molality
i is vant Hoff factor
For NaCl vant Hoff factor is 2( Actually 1.9)
Answer:
2.86L
Explanation:
Given parameters:
V1 = 2.1L
T1 = 200°C = 200 + 273 = 473K
T 2 = 370°C = 370 + 273 = 643K
Unknown:
V2 = ?
Solution:
Since pressure is constant, we apply the Charles's law;
=
V is volume
T is the temperature
1 is the initial state
2 is the new state
=
V2 = 2.86L
Answer:
voltage source
Explanation:
establishes an electric potential difference across the two ends of the external circuit and thus causes the charge to flow. The voltage source is the numerical value of this electric potential difference.
Answer:
pressure will be high because the temp is high, the gas is gonna expand
Explanation:
when temp increases it causes gas to expand which causes high pressure. this is because pv=nrt, p=pressure in atmosphere, v is volume in liters, n is number of particles in moles, t is temp in kelvin is r is ideal gas constant
