Answer:

lighter atoms especially hydrogen

Explanation:

At the heart of the stars, nuclear fusion merges lighter atoms especially hydrogen together in the nucleus of atoms to create new elements.

During nuclear fusion small atomic nuclei combines to form larger ones with the release of a large amount of energy.

The energy released provides the needed temperature for another set of hydrogen atoms to fuse. This process is in turn yields another set of helium atom which releases a lot of energy.

A chain reaction progresses which leads to the formation of new elements.

Which property can be used to tell gold and pyrite apart?

zubka84 [21]

Answer:

D. Malleability

Explanation:

Gold is made up of the element Au and it is a metal.

Pyrite is iron sulfide and it is a non-metal.

They have very similar appearance to such an extent that pyrite is widely called the fool's gold.
To distinguish between the two, we simply explore their metallic properties.
Gold is malleable. Pyrite is not. It will crumble under pressure.

600.0 mL of air is at 20.0 c what is the volume at 60.0

pogonyaev

682mL

Explanation:

Given parameters:

Initial volume of air = 600mL

Initial temperature = 20°C

Final temperature = 60°C

Unknown:

Final volume = ?

Solution:

To solve this problem, we apply Charles's law';

Charles's law states that "at constant pressure, the volume of a given mass of gas is directly proportional to its temperature. "

Mathematically;

$\frac{V_{1} }{T_{1} } = \frac{V_{2} }{T_{2} }$

V₁ is the initial volume of air

T₁ is the initial temperature of air

V₂ is the final volume of air

T₂ is the final temperature of air

To proceed in solving this problem, we need to convert the given temperature to Kelvin;

T K = 273 + T°C

T₁ = 273 + 20 = 293K

T₂ = 273 + 60 = 333K

now input the parameters;

$V_{2} = \frac{V_{1} }{T_{1} } x T_{2} = \frac{600}{293 } x 333$

V₂ = 682mL
