Answer:
0.0102 L or 10.2 mL
Explanation:
From the question given above, the following data were obtained:
Molarity = 0.250 M
Mole = 0.00255 mole
Volume =?
Molarity is simply defined as the mole of solute per unit litre of the solution. Mathematically, it is expressed as:
Molarity = mole / Volume
With the above formula, we can obtain the volume as follow:
Molarity = 0.250 M
Mole = 0.00255 mole
Volume =?
Molarity = mole / Volume
0.250 = 0.00255 / volume
Cross multiply
0.250 × volume = 0.00255
Divide both side by 0.250
Volume = 0.00255 / 0.250
Volume = 0.0102 L
Covert 0.0102 L to mL.
1 L = 1000 mL
Therefore,
0.0102 L = 0.0102 L × 1000 / 1 L
0.0102 L = 10.2 mL
Thus, the volume is 0.0102 L or 10.2 mL
Answer:
Since reactions occur as a result of collisions between particles, the more particles are in a reaction vessel, the higher the concentration of particles, the more collisions are possible. The more collisions that occur, the faster the reaction rate.
Explanation:
These are just some characteristics for a reaction to occur
1 C + O2 = 1 CO2
There is 1 carbon on the left and 1 carbon on the right
There is 2 oxygen on the left and 2 oxygen on the right so the equation is balanced.
Well i think that It is true.
Answer:
The correct option is option e, both A and C
Explanation:
Ethyl butanoate is an ester. Ester undergoes hydrolysis when heated with water containing dilute acids. Ester hydrolysis gives carboxylic acid and alcohol.
Therefore, ethyl butanoate on hydrolysis gives butanoic acid and ethanol.
Amide also undergoes acidic hydrolysis and yields carboxylic acid and amine.
N-methylbutanamide is an amide. It gives butanoic acid and methylamine when undergoes hydrolysis with H2O in the presence of H2SO4.
Hence, the correct option is option e.
