Compare the physical properties of two forms of carbon: diamond and graphite

Chemistry
1 answer:
Mariana [72]3 years ago
5 0

<em>Diamond and graphite are allotropes of carbon  and have various differences in their physical properties.</em>

Explanation:

<u>Diamond:</u>

  1. It is crystalline in nature
  2. Each  Each C is  sp^{3} hybridized and forms 4 covalent binds with neighboring  C atoms
  3. The geometry is tetrahedral
  4. C-C bond length is 154 pm
  5. It has rigid covalent boning which is difficult to break.
  6. It acts as an electric insulator

<u>Graphite:</u>

  1. It has layered structure
  2. Each C atom is sp2  hybridized and forms 3 sigma  bonds with 3 other C atoms. Fourth electron forms pi bond.
  3. The geometry is planar
  4. C-C bond length is 141.5 pm
  5. It is soft. Its layers can be separated easily
  6. It is good conductor of electricity.

This is the comparison of the physical properties of two forms of carbon: diamond and graphite

New substances formed during a chemical reaction are indicated -
Darya [45]

Answer:

on the right side of the equation and are called products

Explanation:

Reactants are on the left side of the equation. When reactants react, they give products.

Products formed are at the right side of the equation.

They are directed as reactant to product using an arrow pointing towards the products.

New substances formed are called products. Several By-Products can also be formed . They are also on the right hand side.

Aliyah marks a line on her driveway with a piece of chalk and another line 50ft away Then she stands with both feet at the line
Mariulka [41]

Answer:

Speed

Explanation:

Aliyah must have been trying to find her speed.

The speed is a measure of how fast an object or a body is and it is calculated by finding the ratio of distance with time. Mathematically,

  speed = \frac{distance}{time} with a unit of m/s.

<em>Hence, with the distance measured on the ground and Aliyah trying to find the time it will take her to cover the distance while running, she must have been trying to find how fast she can run, that is, speed. </em>

State the change in energy that occurs in order to break the bonds in the hydrogen molecules, H2(g) so it can react with O2(g) t
Gemiola [76]

Answer:

Explanation:

Energy is absorbed to break bonds. Bond-breaking is an endothermic process. Energy is released when new bonds form. Bond-making is an exothermic process.

Is h2so4 a Arrhenius acid
MAVERICK [17]
Answer : Yes , H2SO4 is an arrhenius acid

<h2>Explanations : </h2>

• An ,Arrhenius acid ,is a substance that ,dissociates, in water to form ,hydrogen ions (H+).

,

• In other words, an arrhenius acid increases the H+ ion concentration in aqueous solution.

,

• This can be represented by the equation :

H_SO_4^{-\text{ }}\rightleftarrows H^{+\text{ }}+SO_4^{2-}

• Therefore, H2SO4 is a strong arrhenius acid.
