In general, the atomic radius of an atom _______ as you move to the right across the periodic table? increases decreases increas
s344n2d4d5 [400]

Answer: decreases

Explanation:

Atomic radius in a period from left to right decreases due to increase in nuclear charge.

On moving from left to right, electrons are getting added in outer shell and no of protons also increased which results increase in nuclear charge. Increased nulcear charge holds the electrons tigthly hence electrons moves close to nucleus. So radius decreases.

The density (g/L) of CO2 gas at STP ( 273 K, 1.00 atm) is
Triss [41]

The density : 1.96 g/L

<h3>Further explanation</h3>

Ideal gas Law

Pv=nRT

where  

P = pressure, atm , N/m²  

V = volume, liter  

n = number of moles  

R = gas constant = 0.082 l.atm / mol K (P= atm, v= liter),or 8,314 J/mol K (P=Pa or N/m², v= m³)  

T = temperature, Kelvin  

so for density,

MW CO₂ = 44 g/mol

\tt \rho=\dfrac{P\times MW}{RT}\\\\\rho=\dfrac{1\times 44}{0.082\times 273}\\\\\rho=1.96~g/L

What makes a gas a gas?
Grace [21]

Answer:

Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).
