When you become older, your bones start to detrirate, and they relase calcium from your bones, making them weaker. A fifteen year old wont have that happening, meaning a fifteen year old woukdnt need as much of an intake of calcium than the thirty year old.
The chemical formula for the ionic compound calcium acetate is Ca(C2H3O2)2. The subscripts for each element indicate the number of atoms of that element. The absence of a subscript is understood to mean one atom. The two outside the parentheses means that the number of atoms of each element inside the parentheses is multiplied times two. So, in one formula unit of calcium acetate, there are fifteen atoms; one of calcium, four of carbon, six of hydrogen, and four of oxygen.
No! u silly head! An element can have a variety of atoms! When an element has more then five atoms, the average amount of atoms, it is called Anise. When there is more than fifteen, it is called Anisus.
That is the amount of weight it will take to pull on the thread to break it.
depends on your strength level. if you are you only going for strength, around 70. if you are adding more (prayer, range, magic, defence, attack) then probably higher. i was hitting 10's at 70. only because i focused on magic, and strength. hope that helps.
It's generally recommend to take the pill at the same time everyday to maintain effectiveness.
There are 3 carbon atoms in a molecule of C3, as indicated by the subscript "3" following the element symbol C.
15+15+15+15=60
