Hello!
In this case, since the density is computed by dividing the mass of the substance by its occupied volume (d=m/V), we first need to realize that 0.8206 g/mL is the same to 0.8206 kg/L, which means we first need to compute the volume in L:

Then, solving for the mass in d=m/V, we get m=d*V and therefore the mass of gasoline in that full tank turns out:

Best regards!
Answer: Area of a Triangle Equals Base x Height / 3

See explanation.
Explanation:
This isn't chemistry. Its physics. Kinetic energy (water) to electric energy (dam) as the hydroelectric dam works. Then, as the current travels from the plant to your crib, electric energy to heat energy (wire resistance). Then when you are using the dryer electric energy to heat energy (hot air) and sound energy (air particles vibrate due to the heat energy).
Your answer is B because elements within the same column have equal numbers of valence electrons which determines the reactivity of an element.
In the process of photosynthesis, when a glucose molecule is formed, THE HEAT CONTENT OF THE REACTION INCREASES, THUS, THE VALUE OF Q IS POSITIVE.
There are two types of chemical reaction, these are exothermic and endothermic reaction. Exothermic reactions are those reactions that gives off heat when they are occurring while endothermic reactions are those reactions that absorb heat from their environment during the course of reaction. Photosynthesis is an endothermic reactions; it absorbs energy from the environment when it is occurring, thus, the heat content of the product is always more than that of the reactants. The heat content of compounds are represented by letter q. For photosynthesis, q is positive, because there is an increase in the heat content of the product [glucose] formed.
