What would be the mass of gas inside a 3.0-L balloon at 0 degrees Celsius and 1.0 atm filled with carbon dioxide gas? *
Anni [7]

Answer:

5.7 grams is the mass carbon dioxide gas inside a 3.0-L balloon.

Explanation:

Using ideal gas equation:

PV = nRT

where,

P = Pressure of carbon dioxide gas = 1.0 atm

V = Volume of carbon dioxide gas = 3.0 L

n = number of moles of carbon dioxide gas = ?

R = Gas constant = 0.0821 L.atm/mol.K

T = Temperature of carbon dioxide gas =0°C = 0+273= 273 K

Putting values in above equation, we get:

(1.0 atm)\times 3.0 L=n\times (0.0821L.atm/mol.K)\times 273 K\\\\n=0.13 mol

Mass of 0.13 mole carbon dioxide gas :

= 0.13 mol × 44 g/mol = 5.7 g

5.7 grams is the mass carbon dioxide gas inside a 3.0-L balloon.

What is the density (in g/L) of a gas with
viva [34]

Answer:

2.22 g/L

Explanation:

There's a relationship using the ideal gas law between molar mass and density: MM=\frac{dRT}{P}, where MM is the molar mass, d is the density, R is the gas constant, T is the temperature, and P is the pressure.

We know from the problem that MM = 32.49 g/mol, T = 458 Kelvin, and P = 2.569 atm. The gas constant, R, in terms of the units atm and Kelvin is 0.08206. Let's substitute these values into the formula:

MM=\frac{dRT}{P}

32.49g/mol=\frac{d*0.08206*458K}{2.569atm}

Solve for d:

d * 0.08206 * 458 K = 32.49 * 2.569

d = (32.49 * 2.569) / (0.08206 * 458 K) ≈ 2.22 g/L

The answer is thus 2.22 g/L.

Which statement describes the change that occurs during the reaction of tin with lead(II) nitrate? A. Tin atoms give electrons t
timama [110]
Answer is: <span>D. Tin atoms give electrons to lead(II) ions and are oxidized to tin(II) ions.
Chemical reaction: Sn</span>⁰ + Pb²⁺ → Sn²⁺ + Pb.
Tin atom (oxidation number 0) give two electrons to led ions, oxidation number of tin is greater now (oxidation number +2).
<span>Oxidation is loss of electrons.</span>

What are the regions of the spectrum with wavelengths that can pass through the atmosphere called?
motikmotik

Answer:

These regions of the spectrum with wavelengths that can pass through the atmosphere are referred to as "atmospheric windows." Some microwaves can even pass through clouds, which make them the best wavelength for transmitting satellite communication signals.

Explanation:

Hope this helps. Have a great rest of your day :)
