Explanation:
Metals are elements that ionized by loss of electrons.
Ionic and molecular compounds are usually non-metals.
Properties of metals:
- Metals have free mobile electrons and the metallic bonding ensures that.
- They are usually electropositive and freely looses their electrons.
- None of the metal is soluble without a chemical change occurring.
- They are ductile and malleable.
- Metals are good conductor or heat and electricity in their free uncombined state.
- They are lustrous.
B. The specific property of metals accountable for their unusual electrical conductivity is due to the presence of free mobile electrons in their lattices.

Answer:
These are the elements or compounds that enter into a chemical reaction: Reactants
These are the substance(s) formed in a chemical reaction: Products
These are the reactants in the chemical equation C6H1206 +602 --> 6CO2 + 6H20: C6H1206 and 602
These are the reactants in the chemical equation 6 CO2 + 6H2O --> C6H1206 + 6 02: 6 CO2 + 6H2O
These are the reactants in the chemical equation 2 H2 + 02 --> 2 H2O: 2H2 and O2
These are the reactants in the chemical equation 2 H2O --> 2 H2 + O2: 2H2O
<span>Answer: option (1) solubility of the solution increases.
</span><span />
<span>Justification:
</span><span />
<span>The solubility of substances in a given solvent is temperature dependent.
</span><span />
<span>The most common behavior of the solubility of salts in water is that the solubiilty increases as the temperature increase.
</span><span />
<span>To predict with certainty the solubility at different temperatures you need the product solubility constants (Kps), which is a constant of equlibrium of the dissolution of a ionic compound slightly soluble in water, or a chart (usually experimental chart) showing the solubilities at different temperatures.
</span><span />
<span>KClO₃ is a highly soluble in water, so you do not work with Kps.
</span><span />
<span>You need the solubility chart or just assume that it has the normal behavior of the most common salts. You might know from ordinary experience that you can dissolve more sodium chloride (table salt) in water when the water is hot. That is the same with KClO₃.
</span><span>The solubility chart of KlO₃ is almost a straight line (slightly curved upward), with positive slope (ascending from left to right) meaning that the higher the temperature the more the amount of salt that can be dissolved.</span>
By Boyles Law (P1V1=P2V2), substituting values in and solving for V2, we find that the new volume is 3.6 L<span />
Hello ^^
Answer:
D.Triple Bonds
Explanation:
A Triple bond is when three pairs of electrons are shared between two atoms in a molecule. It is the least stable out of the three general types of covalent bonds.
