2CH4 + O2 → 2CO + 4H2
Ca + O2 → CaOH

Answers

Answer:   C2H4 + 3O2 → 2CO2 + 2H2O

Explanation:

2Al + 2O2 → 2AlO + O2            Not Balanced Properly:  2Al + O2 = 2AlO  

C2H4 + 3O2 → 2CO2 + 2H2O  Looks Good

2CH4 + O2 → 2CO + 4H2          Not Correct:  CO should be CO2

Ca + O2 → CaOH                        Not Balanced and No source for the H

Answer:

C. Heat energy is added to the substance, weakening the electrical attraction between molecules.

D. Heat energy is added to the substance, strengthening the electrical attraction between molecules.

Explanation:

1. Heat energy is added to the substance, weakening the electrical attraction between molecules.

2. Both the melting point and boiling point are lower.

3. dipole

4. Water and ethanol have different molecular structures.

5. The lone pairs of electrons in the oxygen atom causes the molecule to be bent; the oxygen atom has a partial negative charge, while the hydrogen atoms have partial positive charges.

[quizlet: captncrun]

Heat is a form factor that changes the solid from light to light to gaseous mediums. The phases take place in a cyclic manner.

The solid to liquid changes take place due to the melting or fusion, solid to gas take lace through the sublimation, liquid to gas is by vaporization, and gas to liquid is condensation. Thus the heat is added and leads to the weakening of the electrical attraction within the molecules.

Hence the correct option is C.

A fusion reaction always creates which of the following?

a A massive amount of energy.
b A massive amount of heat.
C A more massive atomic nucleus.
d A massive number of smaller nuclei.

Answers

A fusion reaction can be regarded as the type of reaction that occurs where two lighter elements come together in a type of reaction giving rise to a heavier/more massive element.

A fusion reaction always creates a more massive atomic nucleus (option c).

When the two lighter nuclei comes together in a reaction, a more heavier/massive nucleus is formed but its mass will still be less than the combined mass of the two reactant nuclei.

This also indicates that the left over mass may have been released as energy.

Answers

A disadvantage of disposing of waste polymers through recycling is that

they must first be separated.

Recycling is the process of forming new polymers and compounds as against their disposal .

Recycling involves separating the items into various sections such as paper,

plastic , metal etc. This is because they both undergo different recycling

processes.

The disadvantage of this process is that it's time consuming and also

expensive as a great amount of time and man power is needed to

separate the waste items.

Answers

Sodium chloride has the highest melting point while iodine has the least melting point.

The melting points of solid substances depends on the nature of intermolecular forces that exists in the substance. The stronger the magnitude of intermolecular forces in a substance, the higher its melting point.

The order of melting points of the solids shown in question is as follows;

1st - Sodium chloride2nd - sucrose3rd - paraffin4th - Iodine

Sodium chloride has the highest melting points because it is an ionic substance. Among the molecular sucrose and paraffin, sucrose has a higher melting point than sucrose because it has a greater molar mass. Iodine, a molecular substance has the least molar mass and the least melting point in the list.

Choose the statement that is TRUE. Question 26 options: Outer electrons efficiently shield one another from nuclear charge. All of the answers are true Valence electrons are most difficult of all electrons to remove. Core electrons effectively shield outer electrons from nuclear charge. Core electrons are the easiest of all electrons to remove.

Answers

The statement which is true is Core electrons effectively shield outer

electrons from nuclear charge.

Core electrons are those which are in close proximity with the nucleus.  The

core electrons repel the outer electrons farther away from the nucleus to

shield it from nuclear charge.

The valence electrons are usually found in the outermost part of the shell

and they are the easiest to remove due to the fact that they have to achieve

a stable octet configuration which makes them easily removed during

chemical reactions.
