Answer:
Angiosperms are vascular plants. ... Unlike gymnosperms such as conifers and cycads, angiosperm's seeds are found in a flower. Angiosperm eggs are fertilized and develop into a seed in an ovary that is usually in a flower. The flowers of angiosperms have male or female reproductive organs.
Answer:
time travel swordman magic
Answer:
( a ) soluble
( b ) soluble
( c ) insoluble
Explanation:
Solubility is determined by the principle , "like dissolves like" .
i.e. ,<u> if a compound is polar then it will dissolve in a polar compound only , </u>and
<u>if a compound is non - polar then it will dissolve in a non - polar compound only .</u>
Hence , from the question ,
( a )
Methanol and water as we know are both polar species , hence , according to the principle - soluble .
( b )
Hexane and cyclohexane
Both the species are polar species , hence , according to the principle - soluble .
( c )
Hexane and water
In this case ,
Hexane , is non polar and water is polar , hence , the mixture will be non soluble .
Answer:
d) All have identical pressures
Explanation:
The kinetic molecular theory explains how gas molecules behave in a container. By this theory, the gas particles behave like hard, spherical objects in a state of constant, random motion; these particles collide between them and at the walls of the container. Besides, the kinetic energy of the gas depends only on the temperature.
The pressure is the force that the particles are applying under some area, so by the theory, it depends on the number of moles (amount of particles that collides and make the force), the volume of the container and the kinetic energy, or the temperature.
Because all gases have the same number of moles and are at the same temperature and the same volume, they'll have the same pressure.
It gives the positive ion and negative ion and the charges
