A pump separates out Argon atoms from all other atoms in air. If a bottle contains 8.34 x 10^22 atoms of argon what is the mass

puteri [66]

Answer:

55.4g

Explanation:

Given parameters:

Number of atoms in the bottle = 8.34 x 10²²atoms

Unknown:

Mass of air in the bottle = ?

Solution:

The given specie is argon.

Molecular mass of Argon = 40g/mol

To find the mass of this Argon ;

Mass = number of moles x molecular mass;

Let us find the number of moles of the Argon;

6.02 x 10²³ atoms can be found in 1 mole of any substance

8.34 x 10²² atoms will give $\frac{8.34 x 10^{22} }{6.02 x 10^{23} }$ mole of Argon

= 0.139mole of Argon

So;

Mass of argon = 40g/mol x 0.139mole = 55.4g

Describe two advantages and two disadvantages of building your 3D model with modeling clay. (5 points)

marishachu [46]

Answer:

A model or simulation is only as good as the rules used to create it. It is very difficult to create an entirely realistic model or simulation because the rules are based on research and past events. The main disadvantage of simulations is that they aren't the real thing.

Hydrogen gas can combine with oxygen gas under certain conditions to form water. Which name is a general term for water in this

antoniya [11.8K]

Product

Explanation:

Water in this reaction is called the product of the reaction.

The product is the new kind of matter formed as a result of a chemical change. They are produced from the combination of reactants.

2H₂ + O₂ → 2H₂O

Reactants Products

A chemical reaction involves the combination of chemical species to form a product. The type of reaction above is a called synthesis reaction.
