Volume of sphere =
where, =
r = radius of sphere
Put the given value of volume in above formula i.e. ()
Thus,
=
=
=
Thus, radius of the carbon atom is
Multicellular organisms contain a vast array of highly specialized cells. Plants contain root cells, leaf cells, and stem cells. Humans have skin cells, nerve cells, and sex cells. Each kind of cell is structured to perform a highly specialized function. Often, examining a cell's structure reveals much about its function in the organism. For instance, certain cells in the small intestine have developed microvilli (hairs) that promote the absorption of foods. Nerve cells, or neurons, are another kind of specialized cell whose form reflects function. Nerve cells consist of a cell body and long attachments, called axons, that conduct nerve impulses. Dendrites are shorter attachments that receive nerve impulses.<span>

Answer:
the model is useful because it helps to knowabout the molecule of an atom
Given an unknown mixture consisting of two substances, a scientist can determine whether a specific mixture is a true solution, a colloid, or a suspension by passing a light through the mixture. They are distinguished by the Tyndall Effect. If the mixture is a solution, light just pass through the mixture. The light does not reflect. If the mixture is a colloid, then light is dispersed or reflected due to the colloidal particles. If the mixture is a suspension, light cannot pass through.
Answer:
W=-37.6kJ, therefore, work is done on the system.
Explanation:
Hello,
In this case, the first step is to compute the moles of each gas present in the given mixture, by using the total mixture weight the mass compositions and their molar masses:
Next, the total moles:
After that, since the process is isobaric, we can compute the work as:
Therefore, we need to compute both the initial and final volumes which are at 260 °C and 95 °C respectively for the same moles and pressure (isobaric closed system)
Thereby, the magnitude and direction of work turn out:
Thus, we conclude that since it is negative, work is done on the system (first law of thermodynamics).
Regards.
