There is no hydrogen in ammonium sulfide it is just 1 ammonium and 1 sulfer
Yes , CH3OH - this is methanol
The question is incomplete, the complete question is:
A chemist prepares a solution of vanadium (III) chloride (VCl3) by measuring out 0.40g of VCl3 into a 50.mL volumetric flask and filling to the mark with distilled water. Calculate the molarity of Cl− anions in the chemist's solution. Be sure your answer is rounded to the correct number of significant digits.
Answer:
0.153M of anions
Explanation:
First we calculate the concentration of the solution. From m/M= CV
m=given mass, M= molar mass, C =concentration of solution, V= volume of solution
Molar mass of compound= 51 + 3(35.5)= 157.5gmol-1
0.4g/157.5gmol-1= C×50/1000
C= 2.54×10-3/0.05= 0.051M
But 1 mole of VCl3 contains 3 moles of anions
Therefore, 0.051M will contain 3×0.051M of anions= 0.153M of anions
As an object is heated up, its atoms and molecules move and collide faster. Geothermal energy is the thermal energy in the earth. Wind. ... total kinetic energy of the particles hat make up a substance.
Answer:
18 electrons
Explanation:
Note: The third energy level can actually hold up to 18 electrons, so it is not really filled when it has 8 electrons in it.
