Answer:

D. They are different from the properties of carbon, oxygen, and hydrogen.  

Step-by-step explanation:

Carbon, oxygen, and hydrogen are all <em>elements. </em>

Sucrose is a <em>compound</em> containing carbon, oxygen, and hydrogen. Its properties are different from those of its elements.

For example, carbon is a <em>black solid,</em> while oxygen and hydrogen are <em>colourless gases</em>. Sucrose is a <em>white solid</em>.

Name the type of polymer formed when propane-1,3-diol and butanedioic acid react together.
Alex Ar [27]

Answer:

Although PPT was initially prepared from terephthalic acid (TPA) and 1,3-propanediol (PDO) in the 1950s, it has been mainly synthesized by transesterification of PDO with dimethyl terephthalate (DMT) similar to poly(ethylene terephthalate) (PET) and poly(butylene terephthalate) (PBT).

When magnesium reacts with chlorine, magnesium ions, Mg2+, and chloride ions, Cl−are formed. In this reaction, magnesium atoms A
Slav-nsk [51]

<u>Answer:</u> In the reaction, magnesium atoms lose electrons.

<u>Explanation:</u>

An ionic compound is defined as the compound which is formed when electron gets transferred from one atom to another atom. These are usually formed when a metal reacts with a non-metal or a metal reacts with a polyatomic ion or a reaction between two polyatomic ions takes place.

Magnesium is 12th element of the periodic table having electronic configuration of 1s^22s^22p^63s^2

This element will loose 2 electrons to form Mg^{2+} ion

Chlorine is 17th element of the periodic table having electronic configuration of 1s^22s^22p^63s^23p^5

This element will gain 1 electron to form Cl^- ion

By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

The ionic compound formed is MgCl_2

Hence, in the reaction, magnesium atoms lose electrons.

Match the part of the wave to the diagram
erik [133]

Answer:

The first high part is Q4, then the low part is Q7, the following high part is Q6, and the energy moving from the next two high points is Q5.

Explanation:

The first high part is Q4, then the low part is Q7, the following high part is Q6, and the energy moving from the next two high points is Q5 because of the diagram.

The overall reaction for photosynthesis can be represented by the following equation:
Svet_ta [14]

B & C

Explanation:

Because the forward reaction results in a positive change in enthalpy, this reaction is endothermic – it takes energy from the environment. Therefore, the forward reaction will be favored if there are an increase n temperatures

Forward and reverse reactions are usually balanced. Removing a product (C6H12O6 in this case) as it is formed, favors the forward's reaction.  This is because the process that results in a reduction in pressure of the system is favoured in the reaction.

What does a base release when it is placed in water?
Alexxx [7]

Answer:

D - Hydroxide Ion (OH-)

Explanation:

A base provides either hydroxide ions (OH–) or other negatively charged ions that combine with hydrogen ions, reducing their concentration in the solution and thereby raising the pH. In cases where the base releases hydroxide ions, these ions bind to free hydrogen ions, generating new water molecules.
