A sample of neon, Ne, occupies 1700. mL at STP. At constant pressure, what temperature is necessary to increase the volume to 2100. mL?

The temperature must be 337.42 K.

Explanation:

At constant pressure and number of moles, using Charles's law  

Given ,  

At STP,

T₁ = 273.15 K

V₁ = 1700 mL

V₂ = 2100 mL

T₂ = ?

Using above equation as:

The temperature must be 337.42 K.

i'm pretty sure it is letter c.) car

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
