Explanation:
A chemical bond which is formed in between positively charged atoms when there is sharing of free electrons in a lattice of cations is known as a metallic bond.
In a pure metal, atoms are surrounded by free moving valence electrons which move from one part of metal to another.
Thus, we can conclude that pure metals are held together by metallic bonds due to attraction between mobile valence electrons and positively charged metal ions.
In a mechanical cycle, mechanical energy (mostly the the rotation) is used to get the desired result. The form of energy remains the same.
<span>In a thermodynamic cycle heat is converted to mechanical energy. That is to say there is conversion of energy.</span>
The number of liters of 3.00 M lead (II) iodide : 0.277 L
<h3>Further explanation</h3>
Reaction(balanced)
Pb(NO₃)₂(aq) + 2KI(aq) → 2KNO₃(aq) + PbI₂(s)
moles of KI = 1.66
From the equation, mol ratio of KI : PbI₂ = 2 : 1, so mol PbI₂ :
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
Where
M = Molarity
n = Number of moles of solute
V = Volume of solution
So the number of liters(V) of 3.00 M lead (II) iodide-PbI₂ (n=0.83, M=3):
Answer: a bench made of composite plastic
Explanation:
The chemical weathering can be defined as the process in which a chemical causes the degradation and decomposition of the rocks into small particles. The iron rods, feldspar, and marble will weather considerably with a greater danger as the have a strong solid body. But plastic when exposed to a chemical agent usually melts and thus there is least or no danger of chemical weathering of plastic.
