Answer:
9√3
Explanation:
Given that :
UV = 18
Angle V = 60°
To obtain the measure of UW = v
Using trigonometry :
Sinθ = opposite / hypotenus
Sinθ = UW / 18
θ = 60°
sin60° = UW / 18
Sin 60° = √3/2
√3 /2 = UW / 18
UW = 18 * √3/2
UW = 9 * √3
UW = 9√3
I believe the answer is 4 because solid are more compacted than liquid and gases and don't move around like liquid or gases. I'm pretty sure they have strong intermolecular forces because of how close they are. The only answer that makes sense is 4.
<h2><u>Answer:</u></h2>
The quantity of protons likewise decides the character of the component. Electrons have a negative charge. The furthest or valence electrons of a particle are the ones that partake in synthetic responses. A component's substance properties rely upon its valence electrons.
The general properties of issue, for example, shading, thickness, hardness, are instances of physical properties. Properties that portray how a substance changes into a totally extraordinary substance are called synthetic properties. Combustibility and consumption/oxidation obstruction are instances of compound properties.
Reactivity with other chemicals.
Toxicity.
Coordination number.
Flammability.
Enthalpy of formation.
Heat of combustion.
Oxidation states.
Chemical stability
Answer:
The configuration of the atom would be 2-8-2.
Explanation:
Any atom of an element combines with other element to complete its octet and become stable.
The electron configuration of the given atom is 2-8-6. That means the atom has 6 electrons in its outermost shell. To become stable the atom should have 8 electrons in its outermost shell. The given atom has 6 electrons so it either lose 6 electrons or gain 2 electrons to complete its octet.
But we know the atom having 5,6,7 electrons in its outermost shell they do not lose, they gain either 3 or 2 or 1 electrons to complete its octet.
So we say that atom with the electron configuration 2-8-6 bond with the atom having electron configuration 2-8-2.
