Answer: ITS THE 3rd one
Explanation:
It’s hard to give it an explanation because i looked it up and saw that same picture with the answer
Answer:
3Mg(s) +2P(s) -------> Mg3P2(s) + energy
Keq= [Mg3P2]/[Mg]^3 [P]^2
Explanation:
The equation for the formation of magnesium phosphide from its elements is;
3Mg(s) +2P(s) -------> Mg3P2(s) + energy
Hence we can see that three moles of magnesium atoms combines with two moles of phosphorus atoms to yield one mole of magnesium phosphide. The equation written above is the balanced chemical reaction equation for the formation of the magnesium phosphide.
The equilibrium expression for the reaction K(eq) will be given by;
Keq= [Mg3P2]/[Mg]^3 [P]^2
107.9 should be it according to my calculations.Please mark as Brainliest!
Molar mass NaCl = 23 + 35.5 => 58.5 g/mol
Volume = 1.0 L
Molarity = 3.5
mass of solute = molas mass ( NaCl) x volume x molarity
mass of solute = 58.5 x 1.0 x 3.5
= 204.75 g of NaCl
hope this helps!
Answer:
it would be 0.341 because if you add 0.229 and 0.112 it will be 0.341
Explanation:
81.8 g/mol
We’re being asked to calculate the molar mass of an unknown acid based on our interpretation of the titration curve.
Recall that at the equivalence point of a titration:
