calcium hydride
Formaldehyde is a better hydride donor than benzaldehyde because it is a stronger reducing agent due to the presence of the aldehyde group, which can readily donate hydride ions. In contrast, benzaldehyde is less reactive as a hydride donor because the aromatic ring stabilizes the carbonyl group, making it less prone to hydride donation.
Oyster shell calcium is derived from oyster shells and contains other minerals besides calcium. Calcium carbonate is a more common form of calcium supplement that is synthetically made and contains only calcium. Oyster shell calcium may be better absorbed by some individuals due to the additional minerals present.
Is garcinia cambogia can be better absorbed by the body thus giving better results when there is no added calcium in it.
Calcium citrate tends to be better absorbed by the body, particularly for individuals with low stomach acid or gastrointestinal issues. Calcium carbonate is generally less expensive and contains a higher percentage of elemental calcium per dose. The choice between the two depends on individual needs and preferences.
The melting point of strontium is 769 C according to both the 9th Edition of the Guinness of Answers and the ASM Handbook of Alloy Phase Diagrams Volume 3. The melting point of Stontium is 777 C according to the 89th Edition of the CRC Handbook of Chemistry and Physics. It is very difficult to obtain strontium in purities greater than 99.9 percent. The most common impurity is oxygen. The second most common impurity is calcium. In calcium, a 0.1 percent oxygen impurity can depress the melting point by 3 degrees from 842 C to 839 C see page 2-120 of the ASM Handbook of Alloy Phase Diagrams. I assume strontium behaves in the same manner. The 769 C value is probably too low due to insufficiently pure samples. Until further experiments are made by scientists using very high purity strontium 99.999 percent or better, the 777 C value in the CRC Handbook of Chemistry and Physics 89th Edition is probably the best value. The 777 C value may still be in error by several degrees.

A better question would be "which elements burn red", as more than one element burns red. Lithium chloride burns red, calcium chloride burnds a red-orange, and strontium chloride burns bright red.
Methyl group is a better leaving group compared to hydride group. This is because methyl group can stabilize the negative charge on the leaving group more effectively than hydride group due to the presence of additional carbon atoms. This makes the departure of a methyl group more favorable in organic reactions.
A mixed calcium and magnesium supplement (such as dolomite) is better than taking just calcium or just magnesium.

Calcium carbonate is better known as limestone or chalk.
if you give me calcium I'll give you a calcu its better than a caterpillar!
CaC2 It is also called Calcium Acetylide which describes the structure better. It forms a chain with a triple bond between the Carbon atoms -Ca-C---C-Ca-C---C-Ca- etc.
Calcium citrate tends to be better absorbed by the body, particularly for individuals with low stomach acid or gastrointestinal issues. Calcium carbonate is generally less expensive and contains a higher percentage of elemental calcium per dose. The choice between the two depends on individual needs and preferences.
Any element in the same group (column) as Mg. The periodic tabe is arranged so that all the elements in the same group, regardless of metal or non-metal, possess similar chemical characteristics.
