Answer:
An is formed when an atom loses or gains one or more electrons. Because the number of electrons in an ion is different from the number of protons, an ion does have an overall electric charge.
Explanation:
Answer:
You can heat it and then let it cool it in a very strong magnetic field.
Milliequivalent is a unit that made from millimol unit multiplied by the valence of the atoms. Calcium has 2 valence electron so the mEq would be twice as much as the mol. The solution has 155meq/liter and the volume is 1850ml. Then, the amount of calcium in the solution should be:
1850ml * (155mEq/1000ml) / (2mEq/mmol)= 143.375mmol= 0.144 mol
The correct answer is temperate deciduous forest.
Temperate deciduous forests are situated in the mid-latitudes, in between Polar Regions and tropics having average annual temperature about 10°C, rainfall between 750 to 1500 mm. There are four distinct seasons and the vegetation includes mostly broad leaved trees such as maple, beech, oak, hickory and chestnut. Leaves fall in winter after changing color in autumn. Leaves grow back in spring. This is an adaption to avoid to live in cold winters.
It is the number of times the Earth has orbited the Sun since the day we were born. If we were to live on another planet in the Solar System our age would be different because each planet takes a different amount of time to orbit the Sun. In other words each planet has a different year length
