Answer:

A - The water cycle

Explanation:

Condensation is the process by which water vapor in the air is changed into liquid water. These clouds may produce precipitation, which is the primary route for water to return to the Earth's surface within the water cycle. Condensation is the opposite of evaporation.

<u>Answer:</u> The unbalanced chemical equation is written below.

<u>Explanation:</u>

Unbalanced chemical equation does not follow law of conservation of mass.

In an unbalanced chemical equation, total number of individual atoms on the reactant side will not be equal to the total number of individual atoms on the product side.

The chemical equation for the reaction of diboron trioxide and magnesium metal follows:

B_2O_3(s)+Mg(s)\rightarrow B(g)+MgO(s)

Hence, the unbalanced chemical equation is written above.

How many Hydrogen atoms are in 4HN₃?
Kazeer [188]
4 Hydrogen Atoms should be correct. Because the 4 infront of it signifies the amount of hydrogen. It would also be 4 hydrogen atoms if it were written as H4N3, because the 4 is still around the H (as long as the 4 is under scored)

Based upon the information provided in the class, which of the following bond types is the strongest? Question options:
Zigmanuir [339]

Answer: A hydrogen bonding is interaction between lone pair and hydrogen atom. An Ion-Dipole interaction is the interaction between an ion formed and a dipole. Dipole forms because of the electronegativity difference between two atom participating in the bond formation, and an ion is formed when an atom gains or lose electron. This ion-dipole interaction is strongest interaction.

Therefore, The right choice is (B)

Draw the structures of the two monomers that react together to form this polyurethane polymer
matrenka [14]

The monomers that react together to form polyurethane polymer are diisocyanate and diol.

<h3>What are polymers?</h3>
  • Polymers are a class of natural or synthetic substances
  • It is made up of small units called monomers arranged in a repeated pattern to form large molecules called macromolecules
  • Cellulose and resins are examples of natural polymers
  • Polyethylene and polychloroprene are examples of synthetic polymers.

Polyurethane polymer is made up of monomers diisocyanate and diol. It is mostly used in home furnishing in flexible form. The structures of monomers are as follows:
