Lastly, Snape thinks we should try one more calculation. What is the retention factor if the distance traveled by the solvent fr
Neporo4naja [7]

Answer:

0.1 is the retention factor.

Explanation:

Distance covered by solvent ,d_s= 2.0 cm

Distance covered by solute or ion,d = 0.20 cm

Retention factor(R_f) is defined as ratio of distance traveled by solute to the distance traveled by solvent.

R_f=\frac{d}{d_s}

R_f=\frac{0.20 cm}{2.0 cm}=0.1

0.1 is the retention factor.

For each of the following cases, identify the order with respect to the reactant, A. Case (A ----> product)
damaskus [11]

Answer:

The answers to the question are

1. 2nd and above order order

2. 2nd order

3. 1/2 order

4.  1st order

5. 0 order

Explanation:

We have \frac{N}{N_{0} } = e^{-\lambda t}

1. For nth order reaction half life  t_{\frac{1}{2} } ∝ \frac{1}{[A_{0} ]^{n-1} }

Therefore for a 0 order reaction increasing concentration of the reactant there will increase   t_{\frac{1}{2} }

First order reaction    is independent  [A₀].

Second order reaction  [A₀] decrease,    increase.

Similarly for a  third order reaction

1. 2nd order

2. 2nd order reaction

3. Order of reaction is 1/2.

4. 1st order reaction.

5. Zero order reaction.

How much energy would be released if 0.00046 kg of plutonium were converted to energy through radioactive decay?
vagabundo [1.1K]
Rdaioactive  decay results in the formation of a different element. Plutonium decays by emitting alpha emission to form uranium. Thermal energy is emitted as the alpha particles are absorbed and the kinetic energy  is converted to heat. The amount of energy is computed by the formula;
E = mc²
E = 0.000046 × (3 ×10^8) 
 Energy = 4.14 ×10^13 Joules

The table below lists norm al and abnormal events. Explain why some events would never happen normally.
vlada-n [284]
Beacause of lack of force in all three scenarios.
In scenario one there’s two forces acting in the bottle atmospheric pressure and gravity.Gravity keeps the ball at the lowest pointwithout force resisting it.
Umber two there’s no other force greater than gravity that would cause movement to the apple..
And number three there are isn’t any force acting in the rubber band greater than the elastic force to make it stretch
Hope this helps and mark as brainliest if you thought it was most helpful :)
