The properties most likely belong to a metal are ductile and malleable.
What is ductility and Malleability?Malleability - Those metals that can be beaten into thin sheets with a hammer or any heavy object. For example - Cu, Au etc
Ductility- The property of the metals which can lead the metals to form them into wires.
Conductivity - Conductivity is the measure of the ease at which an electric charge or heat can pass through a material. For example - Metals are good conductors of heat and electrolytic solution is conductors of electricity.
Metals have many other properties including the given above, like sonority, lustrous surface, very hard etc.
Therefore, The properties most likely belong to a metal are ductile and malleable.

Answer:
The answer is d
Explanation:
True or false When heat flows to an object, it can change states.
Answer: True
Explanation:
The matter exists as solid, liquid or gas. These are called the states of matter. The change of matter from one state to another can be achieved by heating or cooling.
The solid state can be converted into liquid state by providing heat to solid. The heat will make the particles move farther, resulting into liquid state.
Similarly when liquid state is provided heat, it changes to gaseous state. The heat will make the particles move much more faster.
Thus the statement that when heat flows to an object, it can change states is True.
Why do longer wavelengths are considered to have lower frequencies? Make it as elaborate as possible. :D
Answer:
Longer wavelengths self means by it's name that the distance between the trough and crust are lesser than that of shorter wavelengths!
The word Lower frequency implies lower energy, thus light cannot easily penetrate the EM wave to excite electrons.
Examples of EM waves with longer wavelength :
Radiowaves, microwaves, etc..
Predict the balanced insoluble product for the reaction of lead(III) nitrate with ammonium chloride. GIVE ME THE ANSWER NOT A LINK
Answer: [tex]Pb(NO_3)_2(aq)+2NH_4Cl(aq)\rightarrow PbCl_2(s)+2NH_4NO_3(aq)[/tex] .
The insoluble product is lead (II) chloride.
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.
The balanced chemical equation is:
[tex]Pb(NO_3)_2(aq)+2NH_4Cl(aq)\rightarrow PbCl_2(s)+2NH_4NO_3(aq)[/tex]
The insoluble product is lead (II) chloride.

Answer:
A. write balanced chemical equation (including states), for this process.
Explanation:
Almost all hydrocarbon 'burn' reactions involve oxygen; it's by far the most reactive substance in air.
Hydrocarbon combustions always involve
[some hydrocarbon] + oxygen --> carbon dioxide + steam.
C6H6(l) + O2 (g)--> CO2 (g)+ H2O (g)
Balance carbon, six on each side:
C6H6(l) + O2 (g)--> 6CO2 (g)+ H2O (g)
Balance hydrogen, six on each side:
C6H6(l) + O2 (g)--> 6CO2(g) + 3H2O (g)
Now, we have fifteen oxygens on the right and O2 on the left.
Two ways to deal with that. We can use a fraction:
C6H6 (l)+ (15/2)O2 (g)--> 6CO2 (g)+ 3H2O (g)
Or, if you prefer to have whole number coefficients, double everything
to get rid of the fraction:
2C6H6 (l)+ 15O2 (g)--> 12CO2 (g)+ 6H2O (g)
With the SATP states thrown in...
C6H6(l) + (15/2)O2(g) --> 6CO2(g) + 3H2O(g)

The melting point of gallium metal is 29.76⁰C. If a piece of gallium is sliced into three parts, the melting point of each part will be what A: higher than 29.76⁰C. B: 29.76⁰C. C: lower than 29.76⁰C.
Answer:
29.76ºC
Explanation:
The melting point is a physical property of the matter it doesn't change as you slice the gallium into three different parts. Thus, it's the same value 29.76ºC

Explanation:
magnesium + zinc oxide --> magnesium oxide + zinc
Mg + ZnO --> MgO + Zn
Reactants:
- Magnesium
- Zinc Oxide
Products:
- Magnesium oxide
- Zinc
Type of reaction: Displacement Reaction
The provided word equation depicts a chemical reaction between magnesium and zinc oxide that results in the creation of magnesium oxide and zinc.
Magnesium and zinc oxide are the reactants in the process. These are the substances that alter chemically. The process produces magnesium oxide and zinc. These are the new chemicals produced by the chemical process. This reaction undergoes a chemical transformation, as indicated by the term equation. Magnesium oxide and zinc are formed when magnesium interacts with zinc oxide.
The reaction's stoichiometry is not explicitly stated in the word equation. We cannot establish the exact quantities of the reactants and products involved without further information or factors. The term equation denotes that the reaction obeys the rule of mass conservation. The total mass of reactants must equal the total mass of products.
