Answer:
The molarity of this final solution is 0.167 M
Explanation:
Step 1: Data given
Volume of a 0.100 M HNO3 solution = 50.0 mL
Volume of a 0.200 M HNO3 = 100.0 mL
Step 2: Calculate moles
The final molarity must lie between 0.1M and 0.2M
Moles = molarity * volume
Moles HNO3 in 50mL of a 0.100M solution = 0.05 L *0.100 M = 0.005 mol
Moles HNO3 in 100mL of a 0.200M solution = 0.100 L*0.200 = 0.020mol
total moles = 0.005+0.020 = 0.025 moles in 150mL solution = 0.150L
Step 3: Calculate molarity of final solution
Molarity = mol / volume
Molarity 0.025 moles /0.150 L
Molarity = 0.167M
The molarity of this final solution is 0.167 M
The number of waves passing in a certain amount of time
Answer:
mental
Explanation:
the element is vanadium, it is a Transition metal
A is is a double replacement reaction (Cations and anions switch)
B is a Decomposition reaction (Breaks down into simpler substances)
C is a Synthesis or Combination reaction (both are the same thing)
D is a Combustion reaction (compound made of carbon and hydrogen reacts with oxygen)
and E is a Single replacement reaction (Cations trade)
Hope this helps! :)
