How are ionic compounds named?<br><br>

Dimas [21]

Answer:

Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions.

Explanation:

For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion.

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.

a container with a volume of 3.46 liters contains a gas at a pressure of 1.30 atm and temperature of 274.27 kelvins how many mol

balu736 [363]

There are 0.19 ((1.3*3.46)/(0.082*274.27) moles of gas are in the container. This problem can be solved using the ideal gas law formula which stated as PV=nRT where P is the gas' pressure, v is the gas' volume, n is the gas' mole amount, R is the constant gas standard (0.082), and T is the gas' temperature<span>.</span>
