Calculate the grams or milliliters of solute needed to prepare the following solutions. 240.mL of a 20.0% (v/v) acetic acid solu
Nady [450]
Mililiters

% (V/V) = [V of solute / V solution ] *100

20.0 / 100 = V of solute / V solution = V of solute = 0.2 * V of solution
 
     V of solution = 240.0 mL

=> V of solute = 0.2*240.0 mL = 48 mL

Answer: 48 mL

The decomposition reaction of A to B is a first-order reaction with a half-life of 2.42×103 seconds: A → 2B If the initial conce
kipiarov [429]

Answer:

t=23.5min

Explanation:

Hello,

In this case, since the rate equation turns out as shown below due to the first-order kinetics:

\frac{dC_A}{dt}=-kC_A

Its integration results:

\int\limits^{C_A}_{C_A^0} { \frac{dC_A}{C_A}} \,=-k\int\limits^t_0 {} \, dt\\ln(\frac{C_A}{C_A^0})=-kt

However, the rate constant is computed by considering the given half-life time as follows:

k=\frac{ln(2)}{t_{1/2}}=\frac{ln(2)}{2.42x10^3s}=2.86x10^{-4}s^{-1}

In such a way, the required time in minutes to diminish the concentration by 66.8% of the initial turns out:

C_A=0.668C_A^0

ln(\frac{0.668C_A^0}{C_A^0})=-kt

t=\frac{-ln(0.668)}{2.86x10^{-4}s^1}=1408.3s*\frac{1min}{60s} \\t=23.5min

Best regards.

Which of the following lists elements in order of increasing malleability?
hodyreva [135]

Malleability is the property due to which substances tend to hammered into thin sheets when pressure is applied. Malleability is observed in metal as the metal atoms are bound by metallic bonds. The layers of metal atoms can roll over each other without breaking the metal bond when pressure is applied. In the periodic table malleability decreases as the metallic nature decreases. Among the given metals Al is the most metallic element, followed by Zinc an Carbon is a non metal. Therefore, the order of increasing malleability will be C, Zn, Al
