Answer:
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Answer:
0.1688L of the 1M NaOH stock solution
Explanation:
A 215mM = 0.215M solution of NaOH contains 0.215 moles per liter. As you want to prepare 785mL = 0.785L of the 0.215M you will need:
0.785L × ( 0.215mol / L) = 0.1688 moles of NaOH.
<em>These moles of NaOH comes from the 1M stock solution</em>, that means the volume of 1M NaOH solution you need is:
0.1688 moles NaOH × (1L / 1mol) =
<h3>0.1688L of the 1M NaOH stock solution</h3>
2CH4 + 2NH3 + 3O2 ---> 2HCN + 6H2O
10g CH4 x 1molCH4/16.042gCH4 x 2mol HCN/2molCH4 = 0.6mol HCN
12g NH3 x 1molNH3/17.034gNH3 x 2molHCN/2molNH3 = 0.7mol HCN
Methane is the limiting reactant
Use the moles of Hydrogen Cyanide that you would get when used the limiting reactant, Methane
0.6molHCN x 27.028gHCN/1molHCN = 16.2grams --> 16 grams Methane
Because they form the basic building blocks of all visible matter in the universe.
Answer:
The answer to your question is: Molarity = 0.30
Explanation:
Data
V1 = 76 ml
C1 = 1.4 M
V2 = 208 ml
V3 = 104 ml
V water = 153 ml
Process
C1V1 = C2V2
C2 = C1V1/ V2
C2 = (1.4)(76) / 208
C2 = 0.51 M
Molarity = moles / volume
moles = Molarity x volume
moles = 0.51 x 0.208
moles = 0.11 Final volume = 0.208 + 0.153
Molarity = 0.11 / 0.361
Molarity = 0.30
