Tatiana [17]3 years ago
7 0

<u>Answer:</u> The correct answer is Option C.

<u>Explanation:</u>

There are two types of energy sources. They are:

  • <u>Renewable sources of energy:</u> This is defined as the source which does not get depleted or destroyed when they are used. For Example: Wind, solar, geothermal etc..
  • <u>Non-Renewable sources of energy:</u> This is defined as the source which gets depleted or destroyed when they are used. They are present in limited amount. For Example: Coal, natural gas, oil etc..

Hence, the correct answer is Option C.

NaCl + H2SO4 ---&gt; Na2SO4 + HCl<br> Balance the double replacement chemical reaction.
VikaD [51]

Answer:

2NaCl+H2SO4-->Na2SO4+2HCl

Explanation:

There are two Na on the right, so put a 2 in front of NaCl on the left. This makes 3 Cl also, so put a 2 in front of HCl on the right. There are already 2 H on the left, so the equation is balanced.

Which of the following trends can be observed when moving down a column in the periodic table
Vlad [161]

Explanation:

A column on the periodic table represents a period.

These are some of the variations observed across a period;

  • Atomic radii decreases progressively from left to right due to the progressive increase in the nuclear charge without an attendant increase in the number of electronic shells.
  • Ionization energy increases progressively from left to right due to decreasing atomic radii.
  • Electronegativity increases from left to right.
  • Electropositivity decreases across a period.

Hydrophobic compounds dissolve in Select one: a. ionic solvents O b. low dielectric constant solvents c. high dielectric constan
kykrilka [37]

Explanation:

(1.)   A hydrophobic compound is defined as the compound that does not dissolve in water and they contain no charge. Hydrophobic compounds are generally organic in nature.

  • As a result, there occurs no interaction between an ionic compound and hydrophobic compound. This is because ionic solvents or compounds are charged species and hydrophobic compounds do not contain any charge.

Hence, there occurs no interaction between the two.

  • Whereas lower is the dielectric constant of a solvent, less polar it will be in nature. Hence, smaller is the value of a dielectric constant more readily and easily it is able to dissolve a hydrophobic compound.
  • On the other hand, higher is the value of dielectric constant more polar the substance will be in nature. As a result, hydrophobic substance will not dissolve in high dielectric constant solvents and polar solvents such as water.

(2.)   Pyrogen is defined as any substance that is able to cause fever. Bacterial pyrogens are endotoxins and exotoxins.

And, if both of these toxins are not removed from the body then they tend to interact with the mechanism of drug interaction and hence, these lead to unexpected side effects.

Therefore, the statement if formulating an aqueous solution for parenteral administration, filtered and sterile pyrogen free water must be used, is true.
