I would say it’s ‘laws are based on complex theories’.
A scientific law predicts the outcome, while a theory presents a possible explanation to why this outcome is. A law is based of a theory that supports the most data.
Do you have the molecular weight? I’ve never done this type of chemistry before but from researching it the equation is nxAx100/M. n=# of atoms, A=atomic mass, & M=molecule weight. Sorry if this isn’t helpful, if you can give me an example I may be able to help.
Answer:
The coefficients in order are 2, 1, 1
Explanation:
Each side of the reaction needs to have the same number of each element due to conservation of matter.
First I looked at what was uneven, notice there are 2 Na on the left side and 4 Na on the left. The easiest way to fix that is to add a 2 on the Na2HPO4:
2(Na2HPO4)--> Na4P2O7 + H2O
Next take count of each element on both sides to see if the 2 balanced everything:
On the left there are 4 Na, 2 H, 2 P, and 8 O
On the right there are 4 Na, 2 H, 2 P, and 8 O
Since both sides match, you are done!
Answer:
wind
Explanation:
wind is a natural and renewable resource
Answer:
Yes. Burning usually observes this kind of law.
Explanation:
- The law of conversion of mass states that mass can never be formed nor can it be eradicated.
- This means that in case of burning, the amount of matter before and after will remain to be the same.
- It doesn't change at all.
- In conclusion, there's no form of change that can be able to affect matter.
