<u>Answer:</u> Boyle's law states that gas volume is inversely proportional to pressure.
<u>Explanation:</u>
Boyle's law is one of the law used to determine the Ideal Gas equation.
This law states that pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles
Mathematically,
(at constant temperature and number of moles)
The above expression can also be written as:
where,
are initial pressure and volume of the gas
are final pressure and volume of the gas
Hence, Boyle's law states that gas volume is inversely proportional to pressure.
Answer:
<em>The correct option is B) a bridge to connect two landmasses over a stretch of water.</em>
Explanation:
A civil engineer is a person who deals with the designing and construction of infrastructure projects like the construction of roads, buildings, bridges, airports, tunnels etc. Civil engineering is one of the most oldest disciplines in engineering and it is broken into many sub-disciplines. A civil engineer might work for a private or a government-based organization. Hence, among the options mentioned in the question, the construction of a bridge is the most likely function of a civil engineer.
The correct answer is option c
The reactants that would lead to a spontaneous reaction
are Mn2+ and Al3+. Al and Mn
are not because they are stable reactants. Mn and Al3+ are not because Mn is stable. Mn2+ and Al are
not because Al is stable.
Answer:
- The name for the potassium oxide's structure is ionic.
Properties:
- High melting point.
- Soluble in water.
Explanation:
- The ionic structure it is formed by a cation (atom with positive charge) and an anion (atom with negative charge). In this case, potassium is the cation and the oxigen is the anion.
- Since potassium oxide is an ionic compound, it has a high melting point, because of the strong bonds. Also, it is soluble in polar solvents, like water, because its ions generate polarity in the molecule.
