The energy released from 1 gram of uranium is more than 1 million times greater than the energy released from 3 grams of coal. T
SVEN [57.7K]

The energy released from 1 gram of uranium is more than 1 million times greater than the energy released from 3 grams of coal is True.

<u>Explanation:</u>

Nuclear Fission is the process in which splitting of a nucleus takes place that releases free neutrons and lighter nuclei. The fission of heavy elements like "Uranium is highly exothermic" and releases "200 million eV" compared to the energy that is released by burning coal which gives a few eV.

In the given example, it is obvious that the energy released from 1 gram of uranium is more than that of the energy released from 3 grams of coal because the amount of energy released during nuclear fission is millions of times more efficient per mass than that of coal considering only \frac{1}{10}^{th} part of the original nuclei is converted to energy.

In order for a cell to continue being efficient at exchanging materials, what must it do to maintain its surface-to-volume ratio
aksik [14]

Explanation:

It will have to change its form in order for the cell to focus on developing and retaining a viable, in order to be large and narrow as in the situation of the nerve cells or to build a more 'contoured' surface, that is, to establish microvillus.

Hydrogen gas can combine with oxygen gas under certain conditions to form water.
stellarik [79]

Answer:

The correct answer is product.

Explanation:

Hydrogen gas reacts with oxygen gas to generate water molecule.

   2H2+O2 = 2H2O

We all know that that substances which are present at the left hand side of the equilibrium sign act as substrate and the substances those are present in the right hand side of the equilibrium sign are called products.

  From that point of view it can be stated that water or H2O is the product of the reaction between hydrogen and oxygen.

Which of the molecules can be involved in hydrogen bonding?<br><br> HF<br> CH3OH<br> CH4<br> H2
Svetllana [295]

Answer:

HF & CH3OH

Explanation:

Hydrogen bonds are formed as a consequence of  the attractions between a partially positive hydrogen (δ+ hydrogen) atom of a molecule and a lone pair of another electronegative element, such as a nitrogen, oxygen or fluorine molecule of another molecule.

In the case of HF, the partially positive hydrogen atom makes a hydrogen bond with the lone pair of a fluorine atom of another HF molecule in its proximity.  

In the case of CH3OH, the partially positive hydrogen atom (bound to Oxygen) makes a hydrogen bond with the lone pair of an oxygen atom of  another CH3OH molecule in its proximity.
