Is calcium natural or manmade?
Calcium is a naturally occurring element that is found in various minerals such as limestone, gypsum, and fluorite. It is also found in foods like dairy products, leafy greens, and nuts. While some calcium supplements may be manmade, the element itself is natural.
What is the scientific name for epsom salts?
The chemical name is magnesium sulfate, written as MgSO47H2O.
What are 3 ways to prepare hydrogen?
You can prepare hydrogen by adding magnesium to hydrochloric acid. hydrochloric acid + magnesium = magnesium chloride + hydrogen.
Why is the magnesium atom smaller than sodium and calcium?
Magnesium is smaller than calcium because it has less shells of electron although both elements have the same number of valence electrons calcium has one more shell. However sodiums electron configuration is 2.8.1 which gives it three shells of electron- the same as magnesium it also has less protons in it's nucleus so it appears that sodium is smaller than magnesium not the other way around. Hope this helps :)
What flavors does calcium magnesium liquid come in?

Is there a natural water softener?
Yes, one form of natural water softener is water that has passed through limestone, as the calcium carbonate in limestone can help to soften water by removing minerals like magnesium and calcium. Additionally, certain plants like soapwort contain natural saponins that can also act as mild water softeners.
What elements are being measured for in water hardness test?
Alkali-earth metals Calcium and Magnesium as they are capable to form and precipitate as carbonates when heated, or with natural soap when used in washing with tap water.
Are iron copper zinc manganese potassium magnesium sodium and calcium present in a pozzolan?
Pozzolans are natural or artificial materials containing silica and alumina that have cementitious properties when combined with calcium hydroxide in the presence of water. Iron, copper, zinc, manganese, potassium, magnesium, sodium, and calcium may be present in small amounts in certain pozzolans, depending on their source and composition. However, the presence of these elements is not a defining characteristic of pozzolans.
What are the natural elements that make up the earth?
The natural elements that make up the Earth include iron, oxygen, silicon, magnesium, sulfur, nickel, calcium, and aluminum. These elements account for the majority of the Earth's composition, found in the crust, mantle, and core.
