What causes the high luster of a metal?

Chemistry

Answer:

When light is shone on to the surface of a metal, its electrons absorb small amounts of energy and become excited into one of its many empty orbitals. The electrons immediately fall back down to lower energy levels and emit light. This process is responsible for the high luster of metals.

5) Chlorine has 7 valence electrons. Neon has 8 valence electrons. Which on is more likely to undergo a
kari74 [83]

Answer:

well, chlorine will undergo in a chemical reaction

Explanation:

neon has completed valence shells, so it neither need electron and or it also don't need to donate the electrons. hence it will not participate in any chemical reaction and it is stable in nature.

whereas chlorine need one more electron to complete it's valence shell and in order to be stable , so it will try to gain one electron , hence

it will take place in a chemical reaction

Vanyuwa [196]

Answer:

Compound

Explanation:

We want to know if it's a compound or a mixture.

An example of a mixture is salt water: you can heat it hot enough to boil off the water, leaving only the salt. This is a physical change, which is how you know it's a mixture.

Something like gold is a compound: if you heat it, or hit it, you'll still only have gold. You can only break it down by chemical means, which is how you know it's a compound.

A balloon starts out with a volume of 1.3 l at 115.3 kpa. if the temperature is held constant, what would the new volume be if t
Anna35 [415]

The new volume be if the pressure inside the balloon was reduced to 58kpa is 2.58 L.

<h3>What is ideal gas equation?</h3>

Ideal gas equation PV=nRT gives idea about the behavior of gases at different conditions and for this question the equation becomes:

P₁V₁ = P₂V₂, where

P₁ = initial pressure = 115.3 kpa

V₁ = initial volume = 1.3 L

P₂ = final pressure = 58 kpa

V₂ = final volume = ?

On putting all these values in the above equation, we get

V₂ = (115.3)(1.3) / (58) = 2.58 L

Hence resultant volume of gas is 2.58 L.
