We can see here that some common uses of nitric acid:
Nitric acid is a highly corrosive and strong mineral acid. It is a clear or yellowish liquid that is commonly used in various industrial, laboratory, and chemical applications.
In its pure form, nitric acid is a colorless liquid, but it can have a yellowish tint due to the presence of nitrogen dioxide, which forms when nitric acid reacts with air.

Answer: Nitric acid is used in the production of ammonium nitrate and calcium ammonium nitrate which find applications as fertilizers. Ammonium nitrate is also used in the manufacturing of urea ammonium nitrate (UAN) used in fertilizer formulations and also as explosives.
Explanation:
a base
an acid
neutrality
The correct answer is:
neutrality
on the pH scale 7 is neutral above 7 is basic and below 7 is acidic.
Explanation:
The pH is an example of how acidic/basic water is. The scale goes from 0 - 14, with 7 being neutral, pH of less than 7 designates acidity, whereas a pH of greater than 7 intimates a base. pH is really a pattern of the relative amount of free hydrogen and hydroxyl ions in the water.pH is a measure of how acidic/basic water is.
It is neutral because, at this pH, the molar concentrations of Hydroxide and Hydronium are same, therefore the substance is not a base nor an acid.
On the pH scale, a 7 represents neutrality. It is not considered acidic nor basic, but instead, it represents a balanced solution, such as pure water.
On the pH scale, a 7 indicates neutrality. This means that the solution is neither acidic nor basic. The pH scale ranges from 0 to 14, with 7 being the midpoint. Solutions with a pH less than 7 are considered acidic, while those with a pH greater than 7 are considered base or alkaline. So, a pH of 7 is indicative of a perfectly balanced solution, like pure water.

Answer:
independent variable: a variable (often denoted by x ) whose variation does not depend on that of another.
dependent variable: a variable (often denoted by y ) whose value depends on that of another.
Explanation:
Combining carbon and sulfur can result in compounds with various physical states at room temperature, such as solids (e.g., carbon disulfide) or gases (e.g., carbon dioxide). The state depends on the specific compound formed.
The type of chemical bonds and interactions that exist between a compound's components, as well as the temperature and pressure levels, all affect the compound's physical state.
While in their pure elemental forms, carbon and sulfur are both solid at ambient temperature, combining them to create a compound can produce a substance with a variety of qualities.
For instance, carbon and sulfur can combine to generate molecules like carbon disulfide, a volatile and extremely combustible liquid that exists at room temperature and at normal atmospheric pressure.

Protons and electrons have the same mass.
b
Protons have a positive charge and are found in the nucleus.
c
Neutrons are negative and are found outside the nucleus.
d
Electrons are negative and are found in the nucleus.
The statement which is true about the subatomic particles within an atom is as follows:
Thus, the correct option is B.
Subatomic particles may be defined as those particles that significantly compose an atom. Such particles are generally smaller than atoms. In other words, it can be said that the subatomic particles are united together to form any atom.
Protons are positively charged subatomic particles that are found in the nucleus of an atom. Electrons are negatively charged subatomic particles that are significantly revolving around the nucleus of an atom.
Neutrons do not have any charge, they are neutral and are found in the nucleus of an atom along with protons.
Therefore, the correct option for this question is B.
