The rate of particle movement increases, also increases the pressure in the vessel
Answer:
d making models.
Explanation:
When scientists create a representation of a complex process, they are inferring that they are making models.
A model is an abstraction of the real world or a complex process. Models are very useful in developing solutions to processes that are not easily simplified.
- The models allow a part of a body to be simply studied.
- Through this simple abstraction, extrapolations to other parts of the system can be deduced.
- This can give very useful insights into the other parts of the system.
- The heterogeneity of complex processes is a huge limitation to understanding them.
- A homogenous part can be modelled and used to understand the system.
Na5Cl2
penta is 5, so 5 sodiums and di is 2, so 2 chloride
Answer:
17.3124 grams
Explanation:
Given;
Amount of heat to be produced = 175 kJ
Molar mass of the carbon monoxide = 12 + 16 = 28 grams
Now,
The standard molar enthalpy of carbon monoxide = 283 kJ/mol
Thus,
To produce 175 kJ heat, number of moles of CO required will be
= Amount heat to be produced / standard molar enthalpy of CO
or
= 175 / 283
= 0.6183
Also,
number of moles = Mass / Molar mass
therefore,
0.6183 = Mass / 28
or
Mass of the CO required = 0.6183 × 28 = 17.3124 grams
