False
<u>Explanation:</u>
The spacesuit protects the astronauts from various range of temperatures from -156°C to 121°C. Spacesuits have insulation as well as heaters. Spacesuits are equipped with thermal control systems to keep the temperature warm for the astronauts. The heaters in the spacesuit increases the temperature during extreme cold. When the astronaut's body temperature rises, the material absorbs the heat. When it drops, the material gives off the heat, providing warmth. Insulators uses micro-encapsulated phase-change materials.
Answer:
2 double bonds 2 single bonds
A bond involves the swapping of electrons, transfer, etc, like a covalent or ionic bond.
An intermolecular interaction isn't necessarily a bond, but rather a charge that keeps atoms near each other. For example, a glass can swell at the top without overflowing or you can have a meniscus in your graduated cylinder because water sticks to the sides. These are intermolecular interactions, not bonds. An example are London Dispersion Forces. These are intermolecular interactions that control the melting and boiling temperatures of compounds.
Think, if molecules didn't interact with each other, what's holding them together? Why don't they just fly off? Because they interact with each other, we have the states of matter! We need so much heat to give them energy, just so that their own motion can break these forces and cause them to change state.
also i haven't taken chemistry so idk what im doing oops
Answer
D. propyl butanoate
Explanation:
The general formula of an ester is RCOOR'. Esters are named as if the alkyl chain from the alcohol is a substituent. No number is assigned to this alkyl chain. This is followed by the name of the parent chain from the carboxylic acid part of the ester with an –e remove and replaced with the ending –oate.
Therefore, the name of the given ester molecule is:
D. propyl butanoate.
Answer:
Exothermic.
Explanation:
Exothermic is when he leaves the system. A way to remember is the "ex" which is a prefix/root/suffix or something that pretty much means leaving, I think. For example how it's in "Exodus" and "Exit", I think.
Endothermic is when it goes into the system. Similar to "ex" but with inside, I think. For example how it's in "Endoskeleton", I suppose.
