In the cases where no electric current flowed, do compounds form atoms, molecules or lattices in solution?

Which of these is the best explanation for why two negatively charged balloons can repel each other without ever touching ?

Finger [1]

C - electric charges have electric fields. imagine a magnet - charge is distributed in space in the same way magnetic field is. if you can imagine how two magnets of the same sign (++/--) repel each other, you can apply that concept to electric charge/field.

2x = 350- x

3x = 350

x = 350/x

therefore,

x = 116.67cm.

so, (350 - x)cm³ = (350- 166.67)cm³ = 233.33cm³

Hence distance covered by gas A is 116.67cm that by B is 233.33cm

Can someone please help me with this!!!<br><br> ( I chose to stop using water bottles )

Answer:

Flushing goldfish down the toliet

Explanation:

This would help the planet because goldfish are a very evasive species that has been harming our natural enviroments lakes and rivers. Ever since people have been flushing them down the toliet including me since I've had over six they have been finding their ways into our ecosytem and damaging nature. You may think that goldfish are a cute and small pet species to keep in a fish tank but the fish can grow in the right conditons up to 16.1 inches long and can top over five pounds in the wild. Unfortunately most goldfish never thrive like this in fish tanks due to nasty inadequate housing and feeding conditions. And most do not live up to their expected life span in the wild of 15 to even thirty years due to their living conditons. Did you know, goldfish will actually jump out of their tank in a final desperate search for better living conditions and enviroment to live in to meet their physiological needs. But lets get back to the problem so don't be to quick to feel sorry for them, when people flush them down the toliet they repopulate somehow in our lakes and rivers. Even through, it is not clear how they got there, which the suspected culprit is the sewer system. They threaten the natural enviroment tho because they are obnivores and they eat a mixtures of plants and animal specimen. You are probrably thinking why is this a problem, well its because goldfish are particullary greedy eaters and will eat, eat, and feast on the natural envrioment they infestated. And the waste they leave on the enviroment will promote the growth of algae which could cause an extent of enviromental damage. Of course goldfish are not impacted by this algae growth for adaptation reasons which shield them. This is not the main problem tho the main problem of this is that female goldfish can produce up to 1000 eggs at a time. And to make things worse unlike other fish species where the parents of the eggs leave the eggs for predaetors and well the elements of nature the goldfish instead guard their nest foriciously from predaetors that eat fish eggs in which effectively shields the populations young from danger. And to just add to the chaos the goldfish sadly have no real natural predaetor in the unitedstates which just causes more problems since they have no one killing them. And did I mention that they could live up to a real possibility of thirty years. And that they are forocious eaters that could eat a variety of types of foods. All of these facts in the end lead to two things first stop flushing your pet goldfish down the toliet and secondly now you know how golfish impact our planet.

Give brainliest please it took me over thirty minutes of thinking!

On a recent excursion chemistry student extraordinaire, Melvin Blackthorne, found a gold colored coin at a flea market. The vend

Explanation:

What is the density of the coin?

Formular for density = Mass / Volume

Mass of coin = 18.82g

Volume occupied = 7.3ml - 5.2ml = 2.1ml

Density = 18.82 / 2.1 = 8.9619g/ml

what is the mass of the iceberg in metric tons (1 metric ton = 1000 kg)?

Density = 0.9I68g/cm^3

Volume = 35,000 m^3 = 3.5e+10cm^3 (Conversion to cm^3)

Mass = Volume * Density = 3.5 * 10^10 * 0.9I68 = 3.2088 * 10^10g

Upon conversion to kg by dividing by 1000

Mass = 3.2088 * 10^7kg

(1 metric ton = 1000 kg)

Mass = 3.2088 * 10^3 metric tonnes

In your own words explain how Archimedes' principle can be used to measure the volume of an irregularly shaped solid.

By definition, all matter has mass and occupy space. Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces. And the weight of fluid displaced is the volume of fluid.

So the volume is obtaiined by placing the irregularly shaoed solid and noting the volume of fluif displaced.

what volume of water (d = 1.000g/mL) is about to impact Melinda's head?

Volume of sphere = V = (1 / 6) πd³

Inserting the value of V = 10.7 cm

Volume = 641.43cm³
