Answer: a.polluted runoff into nearby ponds
Explanation:
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:
it improves the accuracy of the results
ANSWER:
Your best go is C
EXPLANATION:
Metal is used as a utensil all around the world, c would be your best.
<span>Moles of aluminum carbonate = Mass / Molar mass
= 47.6 g / 233.99 g molâ’1
=0.203 mol
To find moles of oxygen:
In each mole of the carbonate there are 9 moles of oxygen
And thus there are 9 Ă— 0.203 moles of oxygen in the given quantity.
= 1.83 moles of oxygen
Within one mole of oxygen, we have 6.022 x 10^23 atoms
Amount of atoms within 1.827 moles of oxygen = 1.83 x 6.022 x 10^23
= 1.10 x 10^24 atoms</span>
