The next questiоn tests yоur understаnding оf fаtty аcids and their properties. In the figures below, white balls are H atoms; red balls are oxygen atoms and gray balls are carbon atoms. A. Image Description A horizontal chain of atoms. Starting on the left are three white atoms connected by single bonds to a gray atom, which is also connected to a second gray atom by a single bond. The second gray atom, while being connected to the first gray atom, is connected to two white atoms and a third gray atom, each with single bonds. The pattern of gray atoms in the chain continues where they have a gray atom on either side and two white atoms, all connected by single bonds, until the end of the chain of gray atoms is reached. The eighteenth final gray atom, while being connected to the second-to-last gray atom by a single bond, has a double bond with one red atom and a single bond with a second red atom. The second red atom also has one white atom connected by a single bond. B. Image Description A semi-circle chain of atoms. Starting at the top of the semi-circle are three white atoms connected by single bonds to a gray atom, which is also connected to a second gray atom by a single bond. The second gray atom, while being connected to the first gray atom by a single bond, is connected to two white atoms and a third gray atom, each with single bonds. The third gray atom, while being connected to the second gray atom by a single bond, has one white atom connected by a single bond and a fourth gray atom connected by a double bond. The fourth gray atom, while being connected to the third gray atom by a double bond, has one white atom and a fifth gray atom, each connected by a single bond. This pattern of a gray atoms connected to the next gray atoms by a single bond or double bond alternates around the semi-circle until the last gray atom is reached. The eighteenth final gray atom, while being connected to the second-to-last gray atom by a single bond, has a double bond with one red atom and a single bond with a second red atom. The second red atom also has one white atom connected by a single bond. C. Image Description A v-shaped chain of atoms. Starting on the left is one white atom connected by a single bond to a red atom, which is connected by a single bond to a gray atom. This first gray atom is also connected by a double bond to second red atom and a single bond with a second gray atom. The second gray atom, while being connected to the first gray atom by a single bond, has two white atoms and a third gray atom, each connected by single bonds. The pattern of a gray atom having two white atoms and a gray atom on either side continues until the middle of the chain is reached where there is a double bond between two gray atoms. This double bond makes the chain v-shaped. Each of these gray atoms with the double bonds has only one white atom, as well as another gray atom, each connected by single bonds. The pattern then continues again of a gray atom having two white atoms and a gray atom on either side with single bonds until the end of the v-shaped chain is reached. The eighteenth final gray atom, while being connected to the second-to-last gray atom by a single bond, has three white atoms each with single bonds. D. Image Description A slightly diagonal chain of atoms. Starting on the left is one white atom connected by a single bond to a red atom, which is connected by a single bond to a gray atom. This first gray atom is also connected by a double bond to second red atom and a single bond with a second gray atom. The second gray atom, while being connected to the first gray atom by a single bond, has two white atoms and a third gray atom, each connected by single bonds. The pattern of a gray atom having two white atoms and a gray atom on either side continues until the middle of the chain is reached where there is a double bond between two gray atoms. This double bond makes the chain slightly diagonal in its angle. Each of these gray atoms with the double bonds has only one white atom, as well as another gray atom, each connected by single bonds. The pattern then continues again of a gray atom having two white atoms and a gray atom on either side with single bonds until the end of the slightly diagonal chain is reached. The eighteenth final gray atom, while being connected to the second-to-last gray atom by a single bond, has three white atoms each with single bonds. Arrange the molecules according to melting temperature, highest melting point first lowest last. Which of these options has the molecules in the correct order?
In а typicаl fissiоn reаctiоn, uranium-235 absоrbs a neutron and breaks into strontium-90, xenon-144 and two neutrons: 235U + 1n → 90Sr + 144Xe + 1n + 1n When you compare the mass of the products to the mass of the reactants in this fission reaction, what do you find? (Note the question is asking about mass, not mass number.)
