the correct answer would be mixture because compound uses the same element
Temperature has a clear effect on the growth rate of salt crystals. If you carry out an experiment with salt solutions, one at room temperature, one at a colder temperature and one at a warmer temperature, you see that the warm temperature sample grows crystals faster than both the other samples, and the room temperature sample grows faster than the cold sample. This is because a higher temperature increases the rate of evaporation of the solvent, thereby speeding up the rate of growth. Different temperatures produce different amounts of crystals. Colder solutions contract, forcing minerals closer together, so they create bonds, catching impurities in their structure at the same time. These impurities interrupt the crystal pattern, forming a larger number of smaller crystals. In warmer temperatures, the distance between molecules is greater, which allows crystals to form larger, purer shapes at a much more uniform rate than can occur at colder temperatures.
The earth is a vast, complex system powered by two sources of energy: an internal source (the decay of radioactive elements in the geosphere, which generates geothermal heat) and an external source (the solar radiation received from the Sun); the vast majority of the energy in the earth system comes from the Sun.
The molecule of sulfur dioxide has two pi and two sigma bonds and one lone pair of electrons.
<h3>What is lone pair?</h3>
- A lone pair, also known as an unshared pair or a non-bonding pair, is an unshared pair of valence electrons that are not shared with another atom in a covalent connection in chemistry.
- Atom's outermost electron shell contains lone pairs. The Lewis structure can be used to locate them.
- Due to the high electric charge of a lone pair, which results in strong electron repulsion, the bond angle between the bonding pair of electrons reduces.
- They participate in the creation of a dative relationship as well.
