Answer : The partial pressure of is, 66 Kpa
Solution :
According to the Dalton's law, the total pressure of the gas is equal to the sum of the partial pressure of the mixture of gasses.
where,
= total partial pressure = 282 Kpa
= partial pressure of nitrogen = ?
= partial pressure of oxygen = 110 Kpa
= partial pressure of hydrogen = 106 Kpa
Now put all the given values is expression, we get the partial pressure of the nitrogen gas.
Therefore, the partial pressure of is, 66 Kpa
Uranium-235 is composed of 92 protons, 143 neutrons, and 92 electrons.
An electron is a negatively charged subatomic particle.
Uranium-235 is a naturally occurring isotope of uranium, an element characterized by having 92 protons in its nucleus.
As all uranium nuclei have 92 protons, the nucleus of a uranium-235 atom will also have 143 neutrons to give it a total atomic mass number of 235.
Thus, Uranium-235 is composed of 92 protons, 143 neutrons, and 92 electrons.

Answer:
Uranium is element 92, so unionized, it has 92 protons and electrons. U-235 is an isotope with a total of 235 nucleons, so subtract 92 to get 143 neutrons.
Explanation:
Answer;
K+
Explanation;
-Noble gas configuration is the electron configuration equivalent to noble gases or group 8 elements. According to the octet rule an atom of an element gains or looses electrons to attain noble gases configuration which is the stable configuration, such that an atom has attained maximum number of electrons in the outermost energy level.
-For instance potassium is an alkali metal, consisting of one valence electron in the outermost energy level. For an atom of potassium to attain octet configuration or noble gases configuration it will have to loose one electron, thus forming a positively charged ion of potassium, K+.
The correct answer for above statement is:
Prices don’t show the total cost of reconstruction fuels to each of us personally or to the community as a whole. Remembered as externalities, the unknown costs of fossil fuels aren’t described in their business price, notwithstanding severe consequences on our health and environment.
Concerns over a global dependence on fossil fuels include environmental, economic, and social consequences.
The statement about “Concerns over a global dependence on fossil fuels include environmental, economic, and social consequences” is true. The environmental, economic, and social consequences greatly affects the global dependence.
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.

of water, what’s the volume?
Answer:
The volume of the water is 11.5 ml
Explanation:
Volume refers to the space occupied by a fluid.
Usually, a graduated cylinder is used to measure the volume of a fliud. Hence, the volume of the fluid as measured by the graduated cylinder in this case is 11.5 no.
ANSWER ; The moles of solute particles in the solution
