What has a complete ionic equation of Mg s plus Zn2 plus plus 2NO3- Mg2 plus plus 2NO3- plus Zn s?
NO3-
The reaction mgf2 mg2 plus aq plus 2f-aq has reached saturation with concentrations mg2 plus equals 2.8 x 10-5 and f- equals 1.5 x 10-2 what is the value of ksp for mgf2 at this temperature?
6.4 x 10-9
What is the oxidation half-reaction for Mg s plus ZnCl2 aq --- MgCl2 aq plus Zn s?
MgCl2 aq plus Zn s is the oxidation half-reaction for Mg s plus ZnCl2 aq.
What is the oxidation half reaction of mgs plus zncl2aq mgcl2aq plus zns?
It is the zinc that gets reduced, and the magnesium that gets oxidised. This is because zinc has the higher reduction potential of -0,76 V, compared to magnesiums -2,37 V. The oxidation half cell therefore becomes Mg (s) --> Mg2++ 2e-
What is the standard cell notation for a galvanic cell with aluminum and gold?
Type your answer here... Al(s) | Al3+(aq) Mg2+ (aq) | Mg(s)
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+.
Is ca plus 2 or mg plus 2 larger?
The charge of both calcium (Ca2+) and magnesium (Mg2+) is +2. Since they both have the same charge, their size is determined by their atomic radius. In general, magnesium with 12 protons has a slightly smaller atomic radius than calcium with 20 protons, making calcium larger than magnesium.
What is the need for using edta in sds page?
EDTA is used in SDS-PAGE to chelate divalent cations, such as Mg2+ and Ca2+, which can interfere with the denaturation of proteins and disrupt the protein separation process. By removing these cations, EDTA helps to maintain protein stability and integrity during the electrophoresis procedure, leading to more accurate and reliable results.
How does borax serves as water softening agent?
When Borax is added to water, it reacts with Ca2+ and Mg2+, which come out of water as precipitates. The reactions involved are: Ca2+ + Na2B4O7 ----> CaB4O7 + 2Na+ Mg2+ + Na2B4O7 -----> MgB4O7 + 2Na+
What are cations?
Cations are positively charged ions. •Na+ •K+ •Ca2+ •Mg2+
What two elments have ions with a 2 charge?
Mg2+ and Ca2+ (and many more!)
Role of EDTA in lysis buffer?
EDTA in lysis buffer helps to chelate divalent cations (such as Mg2+ and Ca2+) which are cofactors for nucleases, preventing degradation of nucleic acids. This helps to preserve the integrity of RNA and DNA during the lysis process.
Ca2 plus ions separate from Mg2 plus ions?
When a Ca2+ ion and a Mg2+ ion are placed in a solution, they will separate due to their interactions with water molecules. The positively charged ions attract the negatively charged ends of water molecules, leading to the formation of hydrated ions that exist as individual entities in the solution. This separation allows each type of ion to interact independently with other substances in the solution.
What is the electronic configuration of mg2 plus?
Mg2+: [1s22s22p6]
What is the element that binds to troponin?
Calcium ions bind to troponin, leading to a conformational change in the troponin-tropomyosin complex, which allows for the exposure of myosin-binding sites on actin filaments during muscle contraction.
What is Dolomitization?
•2CaCO3 + Mg2+ > CaMg(CO3)2 + Ca2+ • •Fluid flow seems to control precipitation of dolomite
What is the concentration of Mg2 plus?
Magnesium, ion (Mg2+)
