How is the process of converting kiwi into plasticware evidence of a chemical reaction?.

galben [10]

Chemical reaction to biomass, like kiwi, into synthetic materials, like plastic, impact society because kiwi is biodegradable but plastic is not.

The series of chemical reactions used to change natural resources into synthetic products is termed chemical synthesis. Synthetic materials are formed when humans mix substances together for the purpose of creating new materials with desirable properties. Synthetic materials are produced by chemically changing the initial substances to create some material with different characteristics. Some of the best examples of synthetic materials are plastics and medicines. A synthetic substance may or may not be chemically identical to a naturally-occurring substance.

A titanium cube contains 3.10•10^23 atoms. The density of a titanium is 4.50g/cm^3. What is the edge length of the cube?

Lerok [7]

Answer:

1.76cm

Explanation:

We'll begin by calculating the mass of titanium that contain 3.10x10²³ atoms. This can be obtained as follow:

From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02x10²³ atoms. This implies that 1 mole of titanium also contains 6.02x10²³ atoms.

1 mole of titanium = 48g

Now, if 48g of titanium contains 6.02x10²³ atoms,

Then Xg of titanium will contain 3.10x10²³ atoms i.e

Xg of titanium = (48x3.10x10²³)/6.02x10²³

Xg of titanium = 24.72g

Next, we shall determine the volume of the titanium. This is illustrated below:

Density of titanium = 4.50g/cm³

Mass of titanium = 24.72g

Volume of titanium =..?

Density = Mass /volume

Volume = Mass /Density

Volume of titanium = 24.72g/4.50g/cm³

Volume of titanium = 5.49cm³

Finally we shall determine the edge length of the titanium cube as follow:

Volume = L³

5.49cm³ = L³

Take the cube root of both side

L = 3√(5.49cm³)

L = 1.76cm

Therefore, the edge length is 1.76cm

Calculate the number of moles of an ideal gas if it occupies 1750 dm3 under 125,000 Pa at a temperature of 127 C.

Phoenix [80]

Hey there!

* Converts 1750 dm³ in liters :

1 dm³ = 1 L so 1750 dm³ = 1750 liters

* Convertes 125,000 Pa in atm :

1 Pa = 9.86*10⁻⁶ atm so 9.86*10⁻⁶ / 125,000 => 1.233 atm

* Convertes 127ºC in K :

127 + 273.15 => 400.15 K

R = 0.082 atm.L/mol.K

Finally, it uses an equation of clapeyron :

p * V = n * R * T

1.233 * 1750 = n * 0.082 * 400.15

2157.75 = n * 32.8123

n = 2157.75 / 32.8123

n = 65.76 moles

hope this helps!

How does beta decay affect the atomic number?

MA_775_DIABLO [31]

The atomic mass number does not change because a beta particle has a much smaller mass than the atom. The atomic number goes up because a neutron has turned into an extra proton. Beta decay is fundamentally different from alpha decay. An alpha particle is made of two protons and two neutrons.
