Answer:

It's a heterogeneous mixture.

Explanation:

Diamond is made of just one element: carbon. Each carbon atom in diamond is connected to four other carbon atoms, in a crystal that extends on and on. There are other forms of pure carbon where the atoms are bonded differently, notably charcoal and graphite.

An industrial chemist is studying a sample of an unknown metal. Describe two ways he could change the metal physically and two w

Trava [24]

Answer:

Some of the physical changes used by the industrial chemist in order to identify it is by scratching it with other metals in order to find the hardness of it. Trying to deform it in order to find the malleability, and to heat it and measure the temperature in order to find the melting point.

Some of the chemical changes used by the industrial chemist in order to identify it is by inserting it in water to observe that whether it reacts with it or not, if the reaction is violent, then the metal belongs to either group I or group II. The other method is to insert it in acids of distinct strength and to observe its reaction. The metals belonging to the second group react briskly with acids. The other metals react gradually with acids and others are almost inert.

At 850 K, the equilibrium constant for the reaction

Sphinxa [80]

Answer:

Answers are in the explanation.

Explanation:

Given concentrations are:

SO₂ = 0.20M O₂ = 0.60M SO₃ = 0.60M

SO₂ = 0.14M O₂ = 0.10M SO₃ = 0.40M

And SO₂ = 0.90M O₂ = 0.50M SO₃ = 0.10M

In the reaction:

2SO₂(g) + O₂(g) ⇄ 2SO₃(g)

Kc is defined as:

Kc = 15 = [SO₃]² / [O₂] [SO₂]²

Where concentrations of each species are equilbrium concentrations.

Also, you can define Q (Reaction quotient) as:

Q = [SO₃]² / [O₂] [SO₂]²

Where concentrations of each species are ACTUAL concentrations.

If Q > Kc, the reaction will shift to the left until Q = Kc;

If Q < Kc, the reaction will shift to the right until Q = Kc

If Q = Kc, there is no net reaction because reaction would be en equilibrium.

Replacing with given concentrations:

Q = [0.60M]² / [0.60M] [0.20M]² = 15; Q = Kc → No net reaction

Q = [0.40M]² / [0.10M] [0.14M]² = 82; Q > Kc, → Reaction will shift to the left

Q = [0.10M]² / [0.50M] [0.90M]² = 0.015; Q < Kc → Reaction will shift to the right

Pure elemental gases, such as O2 and N2, have very low melting points. At around -220°c. What is one reason that this is the cas

Elanso [62]

Pure elemental gases like oxygen and nitrogen have extremely low melting values of about -220 degrees Celsius because pure gases are nonpolar and only covalently linked. The intensity of intermolecular interactions between molecules determines a substance's melting point.

Which gases make up the elements?

The pure gases element group, includes hydrogen (H), nitrogen (N), oxygen (O), fluorine (F), chlorine (Cl), and noble gases At normal pressure and temperature, the following gases are present: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn) (STP).

Which four types of gases are important?

A four-gas monitor, which measures the four principal gases oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S), and methane (CH4), can safeguard the employees in any setting (CH4).
