The mass of water is expressed in grams (g) or kilograms (kg), and the volume is measured in liters (L), cubic centimeters (cm3), or milliliters (mL). Density is calculated by the dividing the mass by the volume, so that density is measured as units of mass/volume, often g/mL.
Answer:
<h2>The mosquitoes like when its wet and moist than dry temp.</h2>
Answer:
b. 1.5 atm.
Explanation:
Hello!
In this case, since the undergoing chemical reaction suggests that two moles of A react with one moles of B to produce two moles of C, for the final pressure we can write:
Now, if we introduce the stoichiometry, and the change in the pressure 
we can write:
Nevertheless, since the reaction goes to completion, all A is consumed and there is a leftover of B, and that consumed A is:
Thus, the final pressure is:
Therefore the answer is b. 1.5 atm.

A polar molecule is when the arrangement of the atoms in molecules are unequal where one end of the molecule has a positive charge while the other end has a negative charge. Examples of a polar molecule are water, ammonia, hydrogen sulfide and sulfur dioxide. The opposite is called a nonpolar molecule.
Explanation:
Atomic number (Z) = Number of the protons
It means that if the atomic number of C is 6, it implies that the number of protons in carbon is 6 too.
Mass number (M) = Number of the protons + Number of the neutrons
It means that if the atomic mass of C is 12, it implies that the number of protons and the neutrons in carbon is 12.
