Answer:
P(total) = 164 mmHg
Explanation:
Given data:
Partial pressure of helium = 77 mmHg
Partial pressure of nitrogen = 87 mmHg
Total pressure of flask = ?
Solution:
According to Dalton law of partial pressure,
The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.
Mathematical expression:
P(total) = P₁ + P₂ + P₃+ ............+Pₙ
Now we will solve this problem by using this law.
P(total) = P(He) + P(N₂)
P(total) = 77 mmHg + 87 mmHg
P(total) = 164 mmHg
Answer:
The table tennis balls represent neutrons that are released when the nucleus splits and cause other nuclei to split
Explanation:
Nuclear fission is defined as the separation of a nucleus into two smaller nuclei.
It takes a neutron to set off a nuclear fission reaction. When that occurs, neutrons are released and those neutrons in turn are what set off other nuclear fissions. This is defined as a Nuclear Fission Chain Reaction. In the model, the one tennis ball that will be thrown will be modeled as the starting neutron that sets of the initial (first) fission. The mouse traps with tennis balls represent the other nucleuses waiting to be struck by the one tennis ball. Once the initial tennis ball strikes the first mouse trap, that mouse trap will release its tennis ball hitting others and continuing the cycle.
It can also be modeled as such:
Answer:
The molecular formula of Carbon Dioxide is CO2
Answer:
e. do both (a) and (b).
Explanation:
Covalent bond
This is another type of chemical bond, through which atoms can also have 8 electrons at their last energy level, and thus comply with the law of the octet.
The covalent bond is defined as the union of non-metal atoms to share their valence electrons, by means of electromagnetic attractive forces, mainly; Here atoms do not gain or lose their electrons, but share them in quantities of one, two, three and even four in various situations. The last electron layer of the atoms that bind together is intertwined or overlapping, forming the true molecules, contrary to what happens in the ionic bonds, in which the united atoms only approach each other to form true aggregates, instead of true molecules. In general, atoms of organic substances have this type of bond and, in addition, it is very common among atoms of the same class or species (Chlorine with Chlorine, Oxygen with Oxygen, Carbon with Carbon)
Answer:
is formed and it has three unpaired electrons.
Explanation:
Blue reacts with water to produce pink colored complex.
In this complex, ion forms an octahedral complex with six ligands.
As is a weak field ligand therefore ion remains in low spin state.
Hence electronic configuration of ion in this octahedral geometry is with total three unpaired electrons.
