Answer:

Pressure = 4.81atm

Explanation:

Pressure = ?

Temperature = 20°C = (20 + 273.15)K = 293.15K

Volume = 2.50L

R = 0.082J/mol.K

n = 0.5mol

From ideal gas equation,

PV = nRT

P = pressure of the ideal gas

V = volume the gas occupies

n = number of moles of the gas

R = ideal gas constant and may varies due to unit of pressure and volume

T = temperature of the ideal gas

PV = nRT

Solve for P,

P = nRT/ V

P = (0.5 * 0.082 * 293.15) / 2.50

P = 12.01915 / 2.50

P = 4.807atm

P = 4.81atm

The pressure of the ideal gas is 4.81atm

A chemical compound that contains the –NH2 functional group is a(n) _____.
kirill115 [55]
This represents a primary amine. An amine has a nitrogen group that is connected to three substituents via single bonds. The number of carbon-based substitutents determines whether it is primary, secondary, or tertiary. In this case, since 2 substitutents are just hydrogen atoms, and only one has a carbon-based skeleton, this is a primary amine.

An atom X has 2 electrons in its outer orbit. What will it do to form a stable ion?
matrenka [14]

Answer:

In a neutral molecule, the sum of the bonding valance electrons must be equal. So the products of the negative element and its charges and the positive element and its charge must be equal.

Explanation:

C1×N1 = C2×N2

If we have a 3 valance electrons , the 'A' charge will be either +3 or -5 for a full octet and valance electron in 'B' atoms will mostly result in acquisition of additional electrons (2) for an octet and relative charge of -2.

Balancing the two,

3 × A = -2 × B

To be equal, A = 2 and B = 3

Therefore, A²B³

What are standard conditions when working with gases?
zloy xaker [14]

Answer:

STP in chemistry is the abbreviation for Standard Temperature and Pressure. STP most commonly is used when performing calculations on gases, such as gas density. The standard temperature is 273 K (0° Celsius or 32° Fahrenheit) and the standard pressure is 1 atm pressure.
