At STP how many molecules of nitrogen gas are in 224 L?
NeTakaya

Answer:

6.022×10²² molecules

Explanation:

Given data:

Volume of nitrogen = 224 L

Pressure = standard = 1 atm

Temperature = standard = 273 K

Number of molecules = ?

Solution:

PV = nRT

1 atm × 224 L = n × 0.0821 atm.L/mol.K × 273 K

224 atm.L = n ×22.41 atm.L/mol

n = 224 atm.L/22.41 atm.L/mol

n = 10 mol

1 mole contain 6.022×10²³ molecules

10 mol×6.022×10²³ molecules/ 1 mol

60.22×10²³ molecules

6.022×10²² molecules

How does ocean currents affect climate i need it in 8 sentences.
alex41 [277]
Ocean currents move both warm and cool water across many miles. Warm water can be carried to a cooler place like Alaska. It can bring warmer temperatures as well as warmer water to Alaska. Just like the warm water, cold water can do this as well. If cold water moves from Alaska to The Gulf of Mexico, it can cause the water and air to cool. As air travels over the ocean water vapor can condense into it. The current’s flow depends on what variables are in play. There are many different currents that connect together to heat up and cool off as they move.

Can a metal and a nonmetal participate in a combination reaction
nikklg [1K]

Answer:

Yes

Explanation:

A reaction normally takes place between metals and non metals. The metals acts as the electron donors and the non metals acts as the electron acceptors. This exchange of electrons form bonds such as ionic or covalent.

A good example of a reaction between a metal and non metal is Sodium metal and Chlorine(non metal). They form an ionic bond and the product is Sodium chloride.
