- According to Pascal’s principle, for a certain fluid in a totally enclosed system, a change in pressure at a given point in the fluid is transferred to all points in the fluid, as well as to the enclosing walls.
- This is illustrated by the fact that the pressure inside an enclosed system is the same according to the relation [ pressure = force/area ]. Therefore, the change in pressure resulting from squeezing a ketchup bottle will be transferred equally to all parts of that bottle as well as its internal content.
- That’s how hydraulic machines, such as garbage trucks and hydraulic lifts function..
Answer:
Explanation:
To balance equations try to list out each element on both sides and start with the ones that aren't equal
The answer is x = 2.6 x 10^24. Hope this helps. :)
Answer:
Average atomic mass = 58.51047 amu
The symbol is
Explanation:
The formula for the calculation of the average atomic mass is:
Given that:
For first isotope:
% = 68.274 %
Mass = 57.9353 amu
For second isotope:
% = 26.095 %
Mass = 58.9332 amu
For third isotope:
% = 1.134 %
Mass = 61.9283 amu
For fourth isotope:
% = 3.593 %
Mass = 63.9280 amu
For fifth isotope:
% = 0.904 %
Mass = 63.9280 amu
Thus,
Average atomic mass = 58.51047 amu
The symbol is
Answer:
1 pair of nonbonded electrons
3 pairs of bonded electrons
Explanation:
N has 5 electrons in its valence shell while O has 6.
Lewis structure of NO²⁻ is in the image.
N is in the middle of the structure because is the less electronegative atom. 3 electrons of this atom are forming the bonds and 2 electrons are nonbonded.
As you can see, N has 3 pairs of electrons forming 3 bonds with Oxygens and there is 1 pair of nonbonded electrons.
