Many organic compounds are ignitable, putting them in direct flame may cause fires or combustion. it is possible to start a fire on a hot plate, but typically hot plates are not heated as high and the temperature is somewhat controll-able... you can not control the temperature of a bunsen burner very easily i would not through acetone or ethanol on a hot plate, as it can catch on fire or cause burns, but it's much worse with the bunsen burner.

Not washing sidewalks, taking quick showers and consuming local products are changes that will help to save water and reduce the increase in the temperature of our planet.

<h3>How to save water and protect the planet?</h3>

Not washing the sidewalks, there is a lot of water loss when people wash the sidewalks, looking for other ways to clean the neighborhood is necessary.

Taking baths efficiently, not spending much time in the shower, water will be saved, and new measures to anthropize rivers will not be necessary.

Consume locally produced products, avoiding gas emissions with transport, thus preventing a large amount of fuel from being burned.

With this information, we can conclude that not washing sidewalks, taking quick showers and consuming local products are changes that will help to save water and reduce the increase in the temperature of our planet.

Which THREE statements correctly describe the properties of water?
grandymaker [24]
<em>CORRECT STATEMENTS
> Water forms hydrogen bonds with other polar molecules. </em>
<em>> Water is a polar molecule. </em>
<em>> Water dissolves more ionic compounds.</em> 

<em />Water is a polar molecule because of its uneven distribution of electron density. It is made up of two hydrogen atoms and one positive atom.
Since water is a polar molecule, it forms hydrogen bonds with other polar molecules. Though these bonds are relatively weak, however, there are so many of them present in water. 
Water also dissolves most ionic compounds due to the fact that water is a universal solvent. When these compounds are added to water, there will be an interaction between the individual ions and the polar regions of the water molecules and disrupts the ionic bonds. 

<em>INCORRECT </em>
> Liquid water is less dense than water vapor. - Liquid water has a higher density than water vapor. The fact that water vapor rises indicates that it is less dense than water.

>Water dissolves more hydrophobic substances. - Hydrophobic substances do not dissolve easily in water. It is termed as 'hydrophobic" because it means water-fearing.
