Answer choice would be D, answer choice B, is the boxes net force. Velocity = distance/time. The correct answer is D. I hope this helps!
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.
Answer: 0.99 grams of chlorine gas is produced by the reaction of 3.3g of ammonium perchlorate
Explanation:
To calculate the moles, we use the equation:
The decomposition of ammonium perchlorate is :
According to stoichiometry :
2 moles of 
produce = 1 mole of 
Thus 0.028 moles of produce=
of
Mass of 
Thus 0.99 grams of chlorine gas is produced by the reaction of 3.3g of ammonium perchlorate
