Depending on the balloon, the surface will cause friction between the two and oxygen molecules will fuse together to create a sticky sensation
Answer:
Red was originally selected for the same reason. Over a century ago, red was a nice bright color that set fire apparatus apart from most vehicles on the road. Red became traditional, and most fire departments stayed with it. Some firefighters like yellow trucks, some prefer traditional red.
It’s definitely persuade!

See explanation
Explanation:
The molecule IF5 possesses five I-F polar bonds. However, the presence of polar bonds does not automatically imply that the molecule will be polar.
The geometry of the molecule is very important in determining the polarity of a compound. Since IF5 has a lone pair of electrons, the molecule is bent and as such there is a permanent dipole moment created in the molecule thereby making IF5 polar in nature.
Answer:
Densities of the solids and the liquids are expressed in units of grams per cubic centimeter (g/cm³) or in grams per milliliter (g/mL).
Densities of the gases are usually expressed in the units of grams per liter (g/L).
Explanation:
Density of a substance can be defined as the ratio of its mass and its volume.
The constituting atoms in the solids and liquids are fairly packed closely together.
<u>In general, a 1 cm³ or 1 mL volume of most of the solids and the liquids has mass of several grams.</u> Thus, densities of the solids and the liquids are expressed in units of grams per cubic centimeter (g/cm³) or in grams per milliliter (g/mL).
The constituent atoms or the molecules in the gases are far apart from each other when compared to the solids and the liquids.
<u>Thus, gases are much less dense and even about 1 L of gas have mass in range close to 1 gram.</u> Thus, densities of the gases are usually expressed in the units of grams per liter (g/L).
<u>Also, the density of the gases also depend upon the pressure and the temperature but these factors much not influence the density of the solids and the gases.</u>
