When you heat up most substances it gives them more Kinetic energy and the substance becomes less arranged in an ordered state, further apart and move faster. therefore the answer is the first: They gain a higher average kinetic energy
Hope that helps :)
Answer:
The tailor bird has a beak like a sewing needle. As thread, it uses silk from cobwebs, cotton from seeds, and fibers of tree bark. This bird selects two or more large green leaves growing close together at the end of a branch and pulls them together.
Explanation:
Answer;
-Two chlorine atoms
Explanation;
A barium atom attains a stable electron configuration when it bonds with two chlorine atoms.
-Barium is an alkaline earth metal, in group two of the periodic table. Like other alkaline earth metal it has a valency of two which means it reacts by loosing two electrons.
-Chlorine on the other hand is a halogen (group seven element) it reacts by gaining an electron, thus two chlorine atoms will require two electrons. Therefore, Barium would attain a stable configuration by loosing two electrons to two chlorine atoms.
Here we add lone paris,to the structure of caffeine.
<h3>What is caffeine?</h3>
Caffeine is a type of drug. It is used as a cognitive inhancer.
We've been looking at then following structure. We definitely would like to look at it is the geometries of some of the centers. We'll look to it geometry here. Yes, yeah. Down here as well. We have a bonding angle of less than 107.5 because we have a trig onal planer with a bonding angle of 120. This is the site has a geometry with all the bounding angles of 109.5. it is the funding angles of less than 107.5 carbon site here and less than 120 carbon site of here are the tribunal to the parameters. My substitute if luck with the has the same geometry with bonding angles as before.
