Explanation:

The use of NaOH to scrub carbon dioxide;

2NaOH(aq) + CO₂(g) → Na₂CO₃(aq) + H₂O(l)

The Na₂CO₃ would then reacted with CaOH to form limestome;

Na₂CO₃(aq) + Ca(OH)₂(s) → 2NaOH(aq) + CaCO₃(s)

NaOH would then be regenerated and used again to scrub more carbon dioxide.

Carbon dioxide for industrial use can then be obtained by burning the CaCO₃.

CaCO₃(s) → CaO(s) + CO₂(g)

Why do we need to square the period for pendulum experiment? How it is related to obtaining gram ?

andreev551 [17]

Answer:

The period of a pendulum does not depend on the mass of the ball, but only on the length of the string. Two pendula with different masses but the same length will have the same period. Two pendula with different lengths will different periods; the pendulum with the longer string will have the longer period.

How large an expansion gap should be left between steel railroad rails if they may reach a maximum temperature 30.0°C greater th

irina [24]

Answer:

Explanation:

<u>Thermal Expansion</u>

It's the tendency that materials have to change its size and/or shape under changes of temperature. It can be in one (linear), two (surface) or three (volume) dimensions.

The formula to compute the expansion of a material under a change of temperature from $T_o$ to $T_f$ is given by.

$\Delta L=L_o.\alpha .(T_f-T_o)$

Where Lo is the initial length and $\alpha$ is the linear temperature expansion coefficient, which value is specific for each material. The data provided in the problem is as follows:
