Why is formaldehyde a better hydride donor than benzaldehyde comparative view?
The resonating effect of benzene ring makes the removal of hydride slightly difficult as compare to formaldehyde but benzaldehyde also donates hydride as in Cannizzaro;s reaction.
Is garcinia cambogia better with or without calcium in it?
Is garcinia cambogia can be better absorbed by the body thus giving better results when there is no added calcium in it.
What is a good substitute for magnesium?
In what application? Chemically speaking calcium and strontium are fairly similar to magnesium, but depending on what you're trying to do something else might work much better. For example, if you're looking for a light structural metal, aluminium may be an acceptable substitute, but if it's important that the chemistry be similar, aluminium probably won't work.
What is strontium's melting point?
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.
Is calcium citrate a better calcium supplement than calcium carbonate?
Calciun Carbonate and Calcium Citrate are different in that, Carbonate is not as easy to absorb as Citrate. Carbonate in not recommended for elderly folks due to a decrease in stomach acids. Citrate in more easily absorbed and can be taken at anytime, with or without food.
What element emits a yellow light?
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.
Which is a better leaving group methyl group or hydride group?
Based on pKa, hydride would be better (~35 vs. ~45), but there are very few reactions where either would act as a leaving group.
Why is formaldehyde a better hydride donor than benzaldehyde comparative view?
The resonating effect of benzene ring makes the removal of hydride slightly difficult as compare to formaldehyde but benzaldehyde also donates hydride as in Cannizzaro;s reaction.
Is calcium with magnesium better for you?
A mixed calcium and magnesium supplement (such as dolomite) is better than taking just calcium or just magnesium.
Is garcinia cambogia better with or without calcium in it?
Is garcinia cambogia can be better absorbed by the body thus giving better results when there is no added calcium in it.
Do you have slogans for calcium?
if you give me calcium I'll give you a calcu its better than a caterpillar!
What is the chemical formula of calcium carbonide?
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.
What elements are most like magnesium?
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.
Does calcium react with salt water?
Calcium is in water naturally, sea water has about 400ppm calcium. Calcium is an important determinant of water harness, and it also functions as a pH stabilizer, because of its buffering qualities. Calcium also gives water a better taste.

Do pirates fight better drunk?
no... they acctually fight better on calcium aka oranges or other things
