Answer:Carbohydrates improve athletic performance by delaying fatigue and allowing an athlete to compete at higher levels for longer.
Explanation:
The metric system is used because it is based on the number 10. Ten is easy to use for mathematical operations and conversions.
It is also easy to use for scientific notation when you are referring to powers of ten. There are extremely large and extremely small numbers in science. Thus, scientific notation allows for accurate abbreviated ways to symbolize these numbers. For instance, if I were to say 1,000, in scientific notation it would be 1 x 10 ^3. If I was to say 1,000,000, I would scientifically write 1 x 10 ^6.
No
Explanation:
Not all organic substances are soluble in water and will not conduct electricity. Only polar organic compounds are soluble in water and will conduct electricity.
- The general rule of solubility is that like dissolves likes.
- Polar compounds will only dissolve other polar compounds too. Water is a polar solvent.
- Non-polar compounds will only dissolve in non-polar compounds too.
- Since water is a polar organic compound, only polar organic compounds will dissolve in it.
- Not all organic compounds are polar.
- When a compound dissolves in water, it produces ions that makes it able to conduct electricity.
- Fats and oil are insoluble in water

Firstly, the chemical equation between the calcium metal and water will be:
Ca(s) + 2 H₂O(l) → Ca(OH)₂(aq) + H₂(g)
We can see from the equation the bubbles of hydrogen gas which are formed during the reaction stick to the surface of the metal and hence calcium floats on water.
The other metal that will float on the water during the reaction is magnesium which have the same chemical behavior like calcium, we can illustrate that by the chemical equation:
Mg(s) + 2 H₂O(l) → Mg(OH)₂(aq) + H₂(g)
