Answer:
...
Explanation:
in saturated fats there is no double bond between the acids and are tightly packed and unsaturated fats arent tight and loosely packed/put together
saturated- solid at room temperature
unsaturated= liquid at room temperature
two types of unsaturated fats, Polyunsaturated fats and Monounsaturated fats
First shell hold 2. second shell can hold up to 8. so it should be 8.
9.0 grams because the atomic mass of 1 mole of Neon STP(22.4L) is 20.17 and cross multiply 10.0g(given) by the 20.17, and divide by 22.4L to get 9.00 grams of Neon to match 10L container at STP
Answer:
<u><em>1. In the morning the molecules were moving away from each other with a smaller speed than when the truck was carrying the substance.</em></u>
<u><em></em></u>
<u><em>2. The reason is that the molecules contain less average kinetic energy, thus their average speed is lower.</em></u>
<u><em></em></u>
Explanation:
Our model of the state (phases) of the <em>substances</em> describes the <em>molecules </em>of solids as not moving away from each other, they are relatively fixed with respect to each other, just vibrating; the molecules of liquids as free to slide pass each other, which permits they to flow, but not moving away from each other; and the the <em>molecules </em>of the <em>gases</em> as moving away from each other, which is the cause of them occupying the whole space of the container that holds them.
According to that, the substance that the truck was carryng was a gas, because the molecules were moving away from each other.
After parking overnight, where <em>energy transferred out of the substance</em>, in the <em>morning, the substance was a gas</em>. Hence, the <em>molecules were moving away from each other too</em>. This answer the first question.
Since <em>energy was transferred out of the substance</em>, in the morning the temperature of the substance decreased (but no enough to make it a liquid). The average kinetic energy of the gases depends only on the temperature. So, the average kinetic energy of the molecules in the morning was smaller than when the truck was carrying the substance. Since the kinetic energy is proportional to the square of the speed of the molecules, the smaller average kinetic energy means that the average speed of the molecules was smaller too. Hence, in the morning the molecules were moving away from each other with a lower speed than when the truck was carrying the substance.
