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

Answer:6 atoms
Explanation:Each NaOH has one Na and one O and one H. Therefore, 2 NaOH has 6 atoms.
Answer:
Elements that are metals tend to lose electrons and become positively charged ions called cations. Elements that are nonmetals tend to gain electrons and become negatively charged ions called anions. Metals that are located in column 1A of the periodic table form ions by losing one electron.
Explanation:
Cl2 is nonpolar so it has to be only London dispersion force (LDF)
Answer:
The volume of the marble is 10 mL.
Explanation:
From the question given above, the following data were obtained:
Volume of water = 10 mL
Rise in water = 10 mL
Volume of marble =.?
From the question given above, the water level rise by 10 mL when a glass marble was placed into the water.
This is equally the volume of the marble as the marble will displace it's volume when placed in the water according to Archimedes' principle.
Therefore,
Rise in water = 10 mL = volume of marble.
