Gases, fluids, and other solids in contact with a moving object will produce heat due to friction. The contact between molecules or atoms present in gases, fluids, and other solids creates energy and it may be in the form of heat.
The answer is: Heat flow

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:
Which is a base-conjugate acid pair?
NH3 and CIO3-
NH3 and NH4+
HCIO3 and NH3
HCIO3 and NH4+
The example of base-conjugate acid pair is B. NH3 and NH4+.
A base-conjugate acid pair simply means a pair that consist of two substances that only differ by the presence of a proton (H+).
In this case, the example of base-conjugate acid pair is NH3 and NH4+ because bNH4+ is the conjugate acid of the base NH3.

The element that has atoms that can form halide ions is iodine.
Halogens are nonmetals. At room temperature, fluorine and chlorine are gases, bromine is a liquid and Iodine and astatine are solids. Halogens are very reactive, the reactivity decreases from fluorine to astatine. Halogens do not exist in elemental form in nature. Astatine isotopes are radioactive with short half-lives.
One of the definitive properties of halogens is that they are highly reactive. Due to this nature, they can form different compounds such as halides, interhalogens and polyhalogenated compounds. We will look at them in brief below.
These are compounds formed by the reaction of halogens with metals. Metal halides can be highly ionic compounds, monomeric covalent compounds or polymeric covalentcompounds.
Therefore, The element that has atoms that can form halide ions is iodine.
