Answer:
100 kPa
Explanation:
This can be solved with one of the gases law. This law establishes that the pressure of the gas is directly proportional to its temperature: If we increase the temperature, the pressure will increase.
In this case, we decrease the temperature, so its pressure will be lower.
P₁ / T₁ = P₂ / T₂
We convert T° to Absolutes Values
27°C + 273 = 300 K
-173°C + 273 = 100 K
300 kPa / 300 K = P₂ / 100 K
(300 kPa / 300 K) . 100K = P₂
P₂ = 100 kPa
This is the Charles Gay Lussac's law.
Partial pressure is the pressure that is exerted by individual gases.
Partial pressure is calculated as the product of total pressure by the mole fraction of the corresponding gas.
pressures exerted by gases are in three different units, therefore we can convert them all into a common unit - torr
1 - 0.845 atm - 0.854 atm x 760 Torr/atm = 642 torr
2 - 120 torr
3 - 210 mmHg - 1 mmhg is almost equivalent to 1 torr - therefore its 210 torr
total pressure - 642 + 120 + 210 = 972 torr
answer is 972 torr
Answer:
The number ofcarbon atoms in ethanol is 2 and it is 6 in sugar.
Hydrogen atoms is 6 in ethanol and 12 in sugar
Oxygen is 1 atom in ethanol and 6 atoms in sugar.
Explanation:
All these account for them as two different compounds.
The law of conservation of mass states that mass cannot be created or destroyed. It can only be transformed/transferred from one form to another.
