Answer: See attachment.
Explanation:
Exceptions to the octet rule fall into three categories:
- An incomplete octet.
- An odd number of electrons.
- More than eight valence electrons around the central atom.
In addition to the 3<em>s</em> and 3<em>p</em> orbitals, x<u>enon also has 3</u><u><em>d</em></u><u> orbitals that can be used in bonding</u>. These orbitals enable xenon to form an expanded octet.
Answer: Option (b) is the correct answer.
Explanation:
Porosity means the ease with which a fluid can pass through between a rock or cracks etc.
If particles of a soil are flat and even if they are sorted then there will rarely be any space available for fluid or water to pass through it.
If soil particles are round in shape and are sorted then there will be space available for the fluid to pass through it. Hence, this type of soil will be most porous.
Similarly, if soil particles are round but are unsorted then there will be less space available as compared to sorted particles. This is because particles are placed randomly so, somewhere there will be much less space and somewhere there will be large space available. As a result, soil will not be most porous.
If soil particles are flat and unsorted then there will also be less space available for the fluid to pass through it. Thus, soil will be less porous.
Hence, we can conclude that out of the given options, soil B - round, sorted particles is the most porous.
Answer: Total pressure inside of a vessel is 0.908 atm
Explanation:
According to Dalton's law, the total pressure is the sum of individual partial pressures. exerted by each gas alone.
= partial pressure of nitrogen = 0.256 atm
= partial pressure of helium = 203 mm Hg = 0.267 atm (760mmHg=1atm)
= partial pressure of hydrogen =39.0 kPa = 0.385 atm (1kPa=0.00987 atm)
Thus
=0.256atm+0.267atm+0.385atm =0.908atm
Thus total pressure (in atm) inside of a vessel is 0.908
Answer:
B)3
Explanation:
I'm assuming the 2 is meant to be smaller. If it were a regular size 2 the answer would be 2 and that isn't an option
Answer:
Cuando un átomo neutro gana uno o más electrones, el número de electrones aumenta mientras que el número de protones en el núcleo permanece igual. El resultado es que el átomo se convierte en un anión, un ion con una carga neta negativa.
