Magnesium alloys. One of the main differences between magnesium and zinc alloys is that zinc and zinc-aluminum alloys require lower pressure and temperatures for casting. Because of a lower casting temperature, zinc provides a much longer die life than magnesium, which can help reduce production costs.

In the reaction ca + f2 caf2 , what should be the coefficient for f2?
alex41 [277]
Answer : In the reaction of Ca + F _{2} --->CaF _{2}, the coefficient of Ca and F _{2} will be the same which will be 1.

Explanation : As per the rules of writing a chemical equation and balancing it properly, the number of elements in reactants side should be equal to the number of elements generated in product side. Hence when we use 1 molecule of Ca and one molecule of F _{2} then it generates 1 molecule of CaF _{2}.

How does mg2+ block the effect of extracellular calcium on neurotransmitter release?
svetlana [45]
<span>Magnesium is a strong anode than calcium. So, Mg will be oxidized into Mg2+. So instead of having Ca being the reducing agent, Mg will takes its place. That's how the "Blocking" occur.
</span><span>Without Ca2+, no neurotransmitter was released because the exocytosis of the synaptic vesicles is dependent upon Ca2+.
</span>So, when magnesium is added to the extracellular fluid it blocks the calcium channels and inhibits the release of <span>neurotransmitter.</span>

When increased, increases the rate of solution (2 words) not particle size
PilotLPTM [1.2K]

Explanation:

There are quite a number of ways to increase the solubility of substances.

Solution is a homogeneous mixture formed by dissolving a solute in a solvent.

Here are some things that can increase the rate of dissolution;

  • Grinding/pulverizing - helps to increase the surface area for the solvent to react.
  • Stirring - to bring more solvent in contact with the solute intimately.
  • Heating - to facilitate dissolution of solute in solvents.

Suppose you wanted to dissolve 109 g of sodium carbonate in enough water to make 6.00 L of solution. What is the molarity of thi
kumpel [21]
Molarity

a. Na2CO3
                Molar mass = 106 g/mol
    n= 109 g / (106 g/mol) = 1.028 mol

b. 6.00L

c. M=n/V
    M = 1.028 mol / 6.00 L
    M= 0.1713 mol / L

Answer: The molarity of the sodium carbonate solution is 0.1713 mol/L
