Answer:

How to write steam in chemical equations???

Chemical equations are symbolic descriptions of chemical reactions wherein the reactants and the products are represented in terms of their respective chemical equations. They often include the use of symbols to represent variables including the path of the reaction and the physical responses of the reacting entities.

The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as a balanced chemical equation.

Boiling water is a physical change, because it is changing state of matter, there is a controllable temperature change, and you can change it back.

Which example is a trace fossil? {A} dinosaur egg {B} dinosaur footprint {C} dinosaur bone {D} shark tooth
viktelen [127]

dinosaur footprint

Explanation:

A dinosaur footprint is an example of a trace fossil. A trace fossil is a type of fossil that shows the activities of organisms that lived in the past.

  • Fossils are the preserved remains of organisms that lived several years ago.
  • Fossils are usually found in sedimentary rocks and thick layers of ice in temperate and polar regions.
  • Body fossils are the remains of the body parts of an organism that has been preserved. They can be skeletal parts, teeth, eggs e.t.c
  • A trace fossil shows the preserved remains of the activities of an organism.
  • They can be fingerprints, burrows and borings, feccal pellets e.t.c

This puts them in the best position to gain the resources that they need to survive, most notably, the sun. The smaller plants, however, do not have this advantage, and lose out to the trees.</span>

A dehydration reaction starting with 3.8 g cyclohexanol produces 2.6 g cyclohexene. Calculate the theoretical yield for this rea
diamong [38]

Answer:

Theoretical yield of C6H10 = 3.2 g.

Explanation:

Defining Theoretical yield as the quantity of product obtained from the complete conversion of the limiting reactant in a chemical reaction. It can be expressed as grams or moles.

Equation of the reaction

C6H11OH --> C6H10 + H2O

Moles of C6H11OH:

Molar mass of C6H110H = (12*6) + (1*12) + 16

= 100 g/mol

Mass of C6H10 = 3.8 g

number of moles = mass/molar mass

=3.8/100

= 0.038 mol.

Using stoichoimetry, 1 moles of C6H110H was dehydrated to form 1 mole of C6H10 and 1 mole of water.

Therefore, 0.038 moles of C6H10 was produced.

Mass of C6H10 = molar mass * number of moles

Molar mass of C6H10 = (12*6) + (1*10)

= 82 g/mol.

Mass = 82 * 0.038

= 3.116 g of C6H10.

Theoretical yield of C6H10 = 3.2 g
