Answer:
Answer. 600 g CaCl2 would be required to make 2 L of a 3.5 M solution.
Circular lines on topographic map is called Contour lines these lines shown on two dimension map and depict elevation on the ground . the distance of each contour line is set to represent a certain level of elevation with zero being sea level . mostly map use distance between coutour lines is 10 m
Answer:
rate = [NO]²[H₂]
Explanation:
2NO + H2 ⟶N2 + H2O2 (slow)
H2O2 + H2 ⟶2H2O (fast)
From the question, we are given two equations.
In chemical kinetics; that is the study of rate reactions and changes in concentration. The rate law is obtained from the slowest reaction.
This means that our focus would be on the slow reaction. Generally the rate law is obtained from the concentrations of reactants in a reaction.
This means our rate law is;
rate = [NO]²[H₂]
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.
