Answer:

silver

Explanation:

Silver is a metal at room temperature.

The physical state of matter can help us know which of these substances will be the most dense. Density deals the amount of substances per unit volume.

Solids are packed closely and have a definite and ordered arrangement of their atoms. From the list above only Silver is a solid at room temperature.

Bromine is a liquid at room temperature while chlorine and oxygen are gases at room temperature. Liquids and gases do not have more substances per unit volume compared to solids. Therefore, silver should be the most dense.

Answer:

The answer is silver. Silver is the most dense, it's a solid so it is more compact and is obviously the most likely to have more mass to it. option D

Summarize the relationship between volume, temperature and pressure (use words like “inversely
Alinara [238K]

Answer:

P and V: inversely proportional

P and T: directly proportional

V and T: inversely proportional

Explanation:

For pressure and volume, as the volume goes up, meaning the container gets bigger, the pressure would go down. There would be more room in the container, so there would be less collisions between the molecules themselves and between the molecules and the container. This makes them inversely proportional.

For pressure and temperature, as the pressure goes up, there are more collisions, so the particles move faster. Temperature is the speed of the particles, so, since both pressure and temperature would go up at the same time, they are directly proportional.

For volume and temperature, this is similar to the PV relationship. As volume increases, there are less collisions between the particles. This means that the particles are going to move slower. Therefore, as volume goes up, temperature goes down, so they are inversely proportional.

Sorry this is super long, but I hope it fully explains the question for you! ☺

Carbon and silicon are tetravalent but ge sn pb show di valency. Why
Anuta_ua [19.1K]

<u>Answer:</u>

Carbon and silicon both are tetravalent elements as compared to germanium, tin, and lead which are divalent.

That's because Ge, tin, and Pb show inert pair effect and has a greater nuclear effective charge on the 's' electrons due to poor shielding effect.  .That's why these elements are not able to share their valence electrons while carbon and silicon does and show "catenation" which is the ability to form long chain molecules.

What salt is formed by the reaction of potassium hydroxide and hydrochloric acid?
Nina [5.8K]

Potassium hydroxide (KOH) is formed when Potassium forms ionic bonds with OH-ions while Potassium Oxide (K2O) is formed when potassium forms ionic bonds with the Oxide (O2-) ions. i.e. This reaction is a neutralization reaction and occurs when an acid (HCl) reacts with a base (KOH).
