An aluminum can has a height of 4.83 inches, a diameter of 2.60 inches, and a uniform wall/end thickness of 0.0112 inches. If th
Triss [41]
Strategy: with the measures you can determine the volume of the plate of aluminum. Then you can use the density of aluminum to calculate the mass.

With the mass of aluminum and its atomic mass you can find the number of moles and thereafter the number of atoms.

Finally divide the cost by the number of atoms to find the cost of one single atom.

Let's do it.

Volume of aluminum plate, V: 0.0112 in* 4.83 in* 2.60 in * [2.54 cm/in]^3 = 2.305 cm^3

Density of aluminum (from Wikipedia), d = 2.70 g/cm^3

mass, m = d*V = 2.305 cm^3 * 2.70 g/ cm^3 = 6.22 g

Atomic mass of aluminum (from Wikipedia), am = 27 g / mol

Number of moles, n = m/am = 6.22 g / 27 g / mol =   0.23 mol

Number of atoms = n*Avogadro constant = 0.23 mol * 6.022 * 10^23 atoms/mol = 1.39*10^23

Cost per atom = cost of the can / number of atoms =$ 0.05 /1.39*10^23 atoms  =  3.60 * 10^ - 25 $/atom

What is the balanced equation for solid ammonium nitrate (NH4NO3) decomposes explosively to form nitrogen gas, oxygen gas, and w
Karolina [17]

Answer:

2NH4NO3 —> 2N2 + O2 + 4H2O

Explanation:

We begin by writing the skeletal equation as shown below:

NH4NO3 —> N2 + O2 + H2O

The equation can be balance as follow:

There are 4 atoms of H on the left side of the equation and 2 atoms on the right side. It can be balance by putting 2 in front of H2O as shown below:

NH4NO3 —> N2 + O2 + 2H2O

Now we have a total of 4 atoms of O on the left side and 3 atoms on the right side. It can be balance by putting 1/2 in front of O2 as shown below:

NH4NO3 —> N2 + 1/2O2 + 2H2O

Now, multiply through by 2 to clear the fraction as shown below

2NH4NO3 —> 2N2 + O2 + 4H2O

Now the equation is balanced

Predict the most likely bond type for the following.
Amiraneli [1.4K]

Answer:

The three major types of bond are ionic, polar covalent, and covalent bonds. Ionic occurs majorly between metals and non-metals, which allows sharing of electrons to form an ionic compound. Whereas covalent bonding calls for complete transfer of electrons between atoms. Polar covalent bonds have unequaly shared electron-pair between two atoms.

Explanation:

a. Cu (Copper)-<em> ionic bonding </em>

b. KCl (Potassium Chloride) - <em>ionic bonding </em>

c. Si (Silicon) - <em>covalent bonding </em>

d. CdTe (Cadmium Telluride) - <em>polar covalent bonding </em>

e. ZnTe (Zinc Telluride)- <em>polar covalent bonding </em>
