Tin(Sn)
Explanation:
The element with similar chemical properties with lead (Pb) from the given options is tin(Sn).
- Chemical properties of an element depends on the number of valence electrons they have.
- Element in the same group on the periodic table have similar chemical properties because the number of valence electrons are the same.
- Tin and lead belong to group iv on the periodic table.
- Other elements in this group are carbon, silicon, germanium
- All these elements have similar chemical properties.

Answer:
Scientists think that the Earth’s magnetic field is generated by electrical currents flowing in the liquid outer core deep inside the Earth. Although it’s liquid metal, it moves around through a process called convection. And the movements of metal in the core sets up the currents and magnetic field
Explanation:
<u>Answer:</u>
<u>For a:</u> The reaction is a type of synthesis reaction.
<u>For b:</u> The reaction is a type of double displacement reaction
<u>For c:</u> The reaction is a type of combustion reaction.
<u>Explanation:</u>
The given chemical reaction is:
![Ca+Br_2\rightarrow CaBr_2](https://tex.z-dn.net/?f=Ca%2BBr_2%5Crightarrow%20CaBr_2)
The above reaction is a type of synthesis reaction because calcium and bromine are combining in their elemental state to form a calcium bromide compound.
The given chemical reaction is:
![Ca(OH)_2+2HBr\rightarrow CaBr_2+2H_2O](https://tex.z-dn.net/?f=Ca%28OH%29_2%2B2HBr%5Crightarrow%20CaBr_2%2B2H_2O)
The above reaction is a type of double displacement reaction because here exchange of ions takes place.
The given chemical reaction is:
![C_6H_{12}+9O_2\rightarrow 6CO_2+6H_2O](https://tex.z-dn.net/?f=C_6H_%7B12%7D%2B9O_2%5Crightarrow%206CO_2%2B6H_2O)
The above reaction is a type of combustion reaction because a hydrocarbon is reacting with oxygen gas to produce carbon dioxide and water molecule.
They can slosh to one atom and produce a momentary dipole monent.
Answer:
The pH of the substance is 4,06.
Explanation:
The pH indicates the acidity or basicity of a substance. PH values between 0 and less than 7 indicate acidic solutions, 7 neutral and greater than 7 to 14 basic. It is calculated as:
pH = -log (H +)
pH= -log (8.8x10^-5)
<em>pH=4,06</em>
