The compound will have a triple bond.
Explanation:
A compound which consists of carbon and hydrogen atoms is known as a hydrocarbon.
Alkanes, alkenes and alkynes are all hydrocarbons.
For example, is propane.
For example, is ethene.
For example, is propyne.
Thus, we can conclude that out of the given options will have a triple bond.
Answer: V2= 15.0403226 Liters
Explanation:
Use V1/T1=V2/T2
Make sure you change the degrees Celsius to Kelvin. (Kelvin = degrees Celsius +273)
10.0L / 248 K = V2/ 373 K
Cross multiply V1 and T2 and divide by T1
(10.0 L)( 373K)/ 248 K = V2
V2= 15.0403226 Liters (Kelvin cancels out)
Answer : The correct answer is New concentration = 0.125 M and final volume = 0.150 M
Given :
Molarity of NaCl solution = 0.150 M volume of NaCL solution = 125 mL
Volume of water added = 25 mL
1) Final volume = ? 2) New concentration = ?
1) To find the final volume :
New volume = volume of NaCl solution + volume of water added
= 125 mL + 25 mL
= 150 mL
Converting this final volume from mL to L
1 L = 1000 mL
Final volume = 0.150 L
2) To find new concentration :
Following steps can be used :
a) To find mole of NaCl :
Mole of NaCl can be calculated using molarity formula . Molarity can be defined as mole of solute present in Liter of solution (volume ) .It represents Concentration of solution . It used unit as M or . It can be expressed as :
Molarity of NaCl solution = 0.150
Volume of NaCl solution = 0.125 mL or 0.125 L
Plugging these values in molarity formula
Multiplying both side by 0.125 L
Mole of NaCl = 0.01875 mol
b) To find New concentration :
Since the mole of NaCl remians same when water is added . Hence new concentration ( molarity )can be calculated using mole of NaCl and final volume .
Mole of NaCL = 0.01875 mol
Final volume = 0.150 L
plugging values in molarity formula :
New concentration = 0.125 M
