Organs because the tissue when form its make organs
Answer:
The bonds that exist between their atoms and molecules differ on an atomic scale.
Explanation:
The three basic states of matter are solid, liquid, and gas. The major difference between them is the strength of the bonds that hold their molecules together. This affects the way that the molecules interact with each other.
The intermolecular forces binding solids together are very strong. This makes solids rigid and not able to move about freely, but rather, only able to vibrate about a mean position.
The intermolecular forces binding liquid atoms together are a lot weaker than that of solids. This makes liquids able to flow.
The intermolecular forces binding gas molecules together are the weakest. As a result, the gases can move about freely and occupy no definite volume.
Answer:
SiBr₄= 347.7 g/mol
Explanation:
Gram formula mass:
Gram formula mass is the atomic mass of one mole of any substance.
It can be calculated by adding the mass of each atoms present in substance.
SiBr₄:
Atomic mass of Si = 28.1 amu
Atomic mas of Br = 79.9 amu
There are four atoms of Br = 79.9 ×4
There is one atom of Si = 28.1 × 1
Gram formula mass of SiBr₄:
SiBr₄ = 79.9 ×4 + 28.1 × 1
SiBr₄= 319.6 + 28.1
SiBr₄= 347.7 g/mol
<u>Answer:</u>
NO ---> N +2 and O -2
<u>Explanation:</u>
Oxidation numbers are assigned to the elements of a compound to keep a track of the number of electrons each atom has.
Here we have a compound NO (Nitrogen Oxide). The Nitrogen is assigned an oxidation number of +2 while Oxygen in this compound is assigned an oxidation number of -2.
So the algebraic sum of the oxidation numbers of the elements in the compound NO is equal to zero.
