How many moles of Ag will be produced from 46.0 g of Cu, assuming AgNO3 is available in excess?
Xelga [282]

Answer:

1.44 mol

Explanation:

Given data:

Mass of Cu = 46 g

Moles of Ag produced = ?

Solution:

Chemical equation:

Cu + 2AgNO₃      →     2Ag  + Cu(NO₃)₂

Number of moles of Cu:

Number of moles = mass/ molar mass

Number of moles = 46 g/63.546 g/mol

Number of moles = 0.72 mol

Now we will compare the moles of Cu and silver from balance chemical equation:

                 Cu           :               Ag

                  1             :                2

               0.72         :             2×0.72 = 1.44 mol

Thus from 46 g of Cu 1.44 moles of Ag is produced .

Using the VSEPR theory , what would the representation mean A central atom with 2 connected atoms atom with I lone pair of Jone
VLD [36.1K]

Answer:

The molecule has a bent geometry

Explanation:

Let us look again at the principles of VSEPR theory. The shape of a molecule depends on the number of electron pairs that surround the valence shell of the central atom in the molecule.

Lone pairs distort the molecular geometry away from what is expected on the basis of VSEPR theory.

The molecule described in the question has the form AEX2. Two substituents and one lone pair form three electron domains around the central atom. The expected geometry is trigonal planar but the observed molecular geometry is bent because of the lone pairs present.

A container with a volume 2. 0 L is filled with a gas at a pressure of 1. 5 atm. By decreasing the volume of the container to 1.
worty [1.4K]

The resulting pressure of the gas after decreasing the initial volume from 2 L to 1 L is 3 atm.

<h3>What is Boyle's Law?</h3>

According to the Boyle's Law at constant temperature, pressure of the gas is inversely proportional to the volume of that gas.

For the given question we use the below equation is:

P₁V₁ = P₂V₂, where

P₁ = initial pressure of gas = 1.5 atm

V₁ = initial volume of gas = 2 L

P₂ = final pressure of gas = ?

V₂ = final volume of gas = 1 L

On putting all these values on the above equation, we get

P₂ = (1.5atm)(2L) / (1L) = 3 atm

Hence required pressure of the gas is 3 atm.
