Answer
The mole ratio is 1:1
The molar mass of potassium hydrogen phthalate (C8H5KO4) is 204.22g/mol
The mass of C8H5KO4 is 0.43g
The no of moles of C8H5KO4 = mass/molar mass
No of Moles of C8H5KO4 = 0.000210557242mol
From Mole ratio the no of mole of NaOH that reacted with C8H5KO4 0.000210557242
Therefore, molaroty of NaOH is mole of NaOH/the Volume in L
Molaroty if NaOH = 0.000210557242/0.02411 = 0.08733M
<span>0.0165 m
The balanced equation for the reaction is
AgNO3 + MgCl2 ==> AgCl + Mg(NO3)2
So it's obvious that for each Mg ion, you'll get 1 AgCl molecule as a product. Now calculate the molar mass of AgCl, starting with looking up the atomic weights.
Atomic weight silver = 107.8682
Atomic weight chlorine = 35.453
Molar mass AgCl = 107.8682 + 35.453 = 143.3212 g/mol
Now how many moles were produced?
0.1183 g / 143.3212 g/mol = 0.000825419 mol
So we had 0.000825419 moles of MgCl2 in the sample of 50.0 ml. Since concentration is defined as moles per liter, do the division.
0.000825419 / 0.0500 = 0.016508374 mol/L = 0.016508374 m
Rounding to 3 significant figures gives 0.0165 m</span>
Answer:
More reactants and fewer products
Explanation:
If reaction is exothermic it add heat to the environment, so when we add more heat the reaction will move in opposite direction. So, more reactants and fewer products will be formed.
Answer:
If the choices were coal, petroleum, and natural gas, I would say that petroleum has the greatest impact on the CO₂ levels in the atmosphere. I chose petroleum because of transportation, such as cars, trucks, planes, and more.
Answer:
Check the attached one..I only draw the Dot method of Magnesium and Fluorine.. since i love chemistry ..Hope this helps you...Balance you have to do it yourself..If you didn't get the answer let me know in the comments..But you have try okay..
