Chemistry

tatuchka [14]3 years ago

An atom is when the protons and electrons are equal protons have a positive charge and electrons have a negative charge so when they are equal they cancel each other out meaning they have no charge or they are an atom. An ion happens when the protons and electrons aren’t equal, it’s no longer an atom. When you have more protons then electrons you have a positive charged ion. When you have more electrons then protons you have a negative charged ion.

A gas occupies 25.3 at pressure of 790.5 mmHg. Determine the volume if the pressure is reduced to 8.04 mmHg
taurus [48]

Answer:

2487.51.

Explanation:

As per Boyle's law temperature remaining constant the volume of an ideal gas is inversely proportional to its pressure.

pV= k

therefore, p1V1 = p2V2

here V1 = 25.3, p2 = 8.04mm Hg

pressure p1 = 790.5 mm Hg

this means that

25.3×790.5 = 8.04V2

⇒V2= 2487.51

Hence, the required volume is, 2487.51.

When are elements heavier than iron formed by stars?(1 point)
antiseptic1488 [7]

Answer:

The answer <em>should</em> be 2. as a dying star explodes

Explanation:

I do not have this class, but I am knowledgeable when it comes to stars. A dying star undergoing an event known as a Supernova compresses the core of the star much further than normal, causing rapid fusion to occur. This is extremely prominent in very large stars, which form extremely heavy elements such as Gold and Uranium.
