Given the following list of densities, which materials would float in a molten vat of lead provided that they do not themselves

melt? Densities: g/mL: lead= 11.4; glass= 2.6, gold= 19.3, charcoal= 0.57, platinum = 21.4. Enter your answer as a word only. If two or more items would float include the word and between those two items.

The materials that would float in a molten vat of lead are glass and charcoal.

<h3>Which material floats on the solution?</h3>

Glass and charcoal are the materials that would float in a molten vat of lead because they are less denser than the lead solution while on the other hand, platinum and gold get drowned into the solution because of its high density as compared to lead.

So we can conclude that the materials that would float in a molten vat of lead are glass and charcoal.

maks197457 [2]

the answer to your question is

M1V1=M2V2

V2=750-150=600 ml

0.75M*750 ml = M2*600

M2=0.75*750/600 ≈ 9.38 M

Which of the following symbols represents a chlorine ion with a stable arrangement of eight valence electrons?
frozen [14]

A stable arrangement of eight valence electrons : ³⁵Cl⁻¹

<h3>Further explanation</h3>

Chlorine is a halogen gas, located in group 17, p block

Chlorine has an atomic number of 17 and an atomic mass of 35

Electron configuration: [Ne] 3s²3p⁵

If we look at the electron configuration, then Cl will bind 1 more electron so that the configuration is stable like Argon (atomic number 18)

So by binding this one electron, chlorine forms negative ions (anions)

³⁵Cl⁻¹

B. Cl⁻² binds 2 electrons, exceeding the octet rule

C. Cl⁺¹, releases 1 electron, remains unstable

D. Cl, the neutral form of Cl, is still unstable with a 7-electron valence configuration
