Who is more active Mg or Ca?
Ca is more active because it has an atom that is large. The larger the distance the smaller the force. If you want more information you should visit Which_is_more_reactive_Mg_or_Ca_Why
What is the equation balance and identify the type of reaction of Ca Mg(NO3)2?
The balanced equation for Ca + Mg(NO3)2 would be Ca + Mg(NO3)2 -> Ca(NO3)2 + Mg. This is a double displacement reaction, where the calcium (Ca) and magnesium (Mg) ions switch places with the nitrate ions (NO3).
What does Ca and Mg in science stand for?
In chemistry Ca stands for calcium and Mg stands for magnesium.
Which of the following elements has the lowest electronegativity ba ca mg sr?
Mg (magnesium) has the lowest electronegativity among Ba, Ca, Mg, and Sr.
Which ion has the smallest ionic radius Mg2 plus or Ca2 plus?
Mg2+ has the smaller ionic radius compared to Ca2+ because as you move down a group in the periodic table, the ionic radius increases due to the addition of electron shells. Mg and Ca are in the same group, but Ca has more electron shells than Mg, resulting in a larger ionic radius for Ca2+.
Does Mg or Ca react faster with CO2 and why?
This Ca2+ eventually is transported to the ocean where it reacts with dissolved CO2 to form limestone. ... is a net CO2 sink because it produces abundant Ca2+ very little CO2. ... This article does not cite any references or sources. .... 1000 mg will provide 210 mg of calcium. It is more expensive than calcium.so its Mg
Does Mg have more metallic character than Ca?
Yes, Magnesium (Mg) has more metallic character than Calcium (Ca) because it has a smaller atomic radius and higher ionization energy, leading to stronger metallic bonding and more typical metallic properties like high electrical conductivity and ductility.
How does the reactivity of the elements in group 2 change on descending the group?
As you go down the Group 2 (alkaline earth elements) elements they become more and more reactive. i.e. H2O+Ca=Ca(OH)2+H2 there is more hydrogen (g) created and at a faster pace than H2O+Mg=Mg(OH)2+H2.
How does Geochemical controls on biomineralization?
•Ocean geochemistry can control biomineralization of shells •Mg/Ca is high- aragonite shells (~4) •Mg/Ca is low- calcite shells (~<1)
1 iu is equal to how many mg?
The international unit varies according to the substance. An IU is the amount of something that is needed to produce an effect which has been agreed upon as a standard. So, 1000 IU of Vitamin D has a different mass than 1000 IU of Vitamin C.
What is the third element in the alkaline earths?
Mg-Y-ca
Which is more 7.5 mg or 15 mg?
15 mg is more than 7.5 mg.
