Answer:
the answer I am pretty sure is A
Explanation:
Because the way that a generator works is moving electric current around a wire and using magnets to make more energy. please tell me if I am wrong.
Answer:
Lake and River pollution?
Explanation:
The temperature that must be to freeze the solution would be -21.1 ° C.
<h3>How to calculate the freezing temperature of this solution?</h3>
To calculate the freezing temperature we must take into account the following information.
- Solution with a salt concentration of 10% is frozen at -6°C
- Solution with a salt concentration of 20% is frozen at -16°C
- Solution with a higher concentration is frozen at -21.1°C
According to the above, it can be inferred that the puddle has a 50% concentration of salt because they had 12 kg of water and 6 kg of salt.
So the lowest freezing temperature would be 21.1°C because the puddle is 50% concentrated.
Note: This question is incomplete because there is some missing information. Here is the missing information:
- A 10% salt solution freezes at about 20°F (-6°C), and a 20% solution freezes at 2°F (-16°C).
- The lowest freezing point obtainable for salt solutions is −21.1 °C

Well, a compound has a total charge of 0. So, it's electrically neutral. Since the X is 3+ and the Y is 3- they add to 0. Meaning no subscripts are necessary. Why don't you try a different combo?
Like:
A^3 and B^1-, to get a 3- charge you need 3xB^1- so the formula is AB3

Answer:
carbon dioxide is fixed or incorporated into organic molecules.
Explanation:
Carbon dioxide fixation is the conversion of inorganic carbon into organic carbon.
In photosynthesis CO2 is converted into glucose i.e inorganic carbon (CO2) is converted into organic molecule (glucose).
