Which mineral is commonly mined as a source of the element lead Pb?
The mineral commonly mined as a source of the element lead (Pb) is galena. Galena is primarily composed of lead sulfide (PbS) and is the most important ore of lead. It typically has a metallic luster and a distinctive gray color. Additionally, galena can also contain silver, making it valuable for both lead and silver extraction.
What is the Lewis dot diagram for Galena?
Galena (PbS) consists of lead (Pb) and sulfur (S) atoms. In a Lewis dot diagram for galena, the lead atom would be represented with its valence electrons shown as dots around it, while sulfur would have its valence electrons depicted as well. Lead typically has four valence electrons and sulfur has six, so the diagram would show lead sharing its electrons with sulfur to form the bond. However, as a compound, the Lewis structure would mainly focus on the ionic interaction, showing lead as a cation (Pb²⁺) and sulfur as an anion (S²⁻) without explicit dot representation for the ionic bond.
What is the mass percent of pb in lead sulfide?
To find the mass percent of lead (Pb) in lead sulfide (PbS), you first need to determine the molar masses of lead and sulfur. The molar mass of Pb is approximately 207.2 g/mol, and the molar mass of sulfur (S) is about 32.07 g/mol. Therefore, the molar mass of PbS is 207.2 g/mol + 32.07 g/mol = 239.27 g/mol. The mass percent of Pb in PbS is then calculated as (207.2 g/mol / 239.27 g/mol) × 100%, which is approximately 86.5%.
What is wrong this element symbol CA?
It has two capital letters, and is the abbreviation for the state of California. Elements that have two letters (like Pb for lead, Fe for iron) only have one capital letter.
If the pattern of ions shown here for galena is expanded in every direction how many sulfide ions would sorround each lead ion?
In galena (PbS), the structure consists of lead ions (Pb²⁺) surrounded by sulfide ions (S²⁻). Each lead ion is coordinated by four sulfide ions in a tetrahedral geometry. Therefore, if the pattern is expanded in every direction, each lead ion will still be surrounded by four sulfide ions.
What is the percent composition of oxygen in lead2 nitrate?
The molecular formula for lead(II) nitrate is Pb(NO3)2. To calculate the percent composition of oxygen in lead(II) nitrate, you need to consider the molar mass of oxygen in the formula. Since there are three oxygen atoms in one formula unit of Pb(NO3)2, the percent composition of oxygen can be calculated as (3 x oxygen atomic mass) / (molar mass of Pb(NO3)2) x 100%.
What is the Latin scientific name for lead galena?
The Latin scientific name for lead galena is PbS, where Pb stands for lead (plumbum in Latin) and S stands for sulfur. Lead galena is a mineral form of lead sulfide.
Does Galena have lead in it?
Yes, the chemical formula is PbS (lead sulfide) Pb=lead S=sulfur
Which mineral is commonly mined as a source of the element lead Pb?
The mineral commonly mined as a source of the element lead (Pb) is galena. Galena is primarily composed of lead sulfide (PbS) and is the most important ore of lead. It typically has a metallic luster and a distinctive gray color. Additionally, galena can also contain silver, making it valuable for both lead and silver extraction.
What is the balanced chemical equation for iron plus lead 2 sulfate react forming iron 2 sulfate plus lead?
The reaction is:Fe + PbSO4 = Pb + FeSO4
Which will lose an electron to form ions P Fe Pb Se?
se
What is chemical formula of galena?
Galena's chemical name is - lead sulfide (PbS)
Does galena have ionic bonds?
Yes, galena (PbS) has ionic bonds. Lead (Pb) is a metal, while sulfur (S) is a non-metal, leading to the formation of ionic bonds between the positively charged lead ions and the negatively charged sulfur ions in the compound.
The mineral galena is the chief ore of which metal?
Galena is the chief ore of lead. It is a lead sulfide mineral that is the most important source of lead. Lead is used in a variety of applications, including batteries, construction, and plumbing.
Will iron metal react with lead nitrate?
Yes, it will because iron is more reactive than lead. Unbalanced Equation : Fe + Pb(NO3)2 => Pb + Fe(NO3)3 Balanced Equation : 2Fe + 3Pb(NO3)2 => 3Pb + 2Fe(NO3)3
What cu fe pb mg al o n h are all examples of?
These are all chemical elements found on the periodic table. Cu is copper, Fe is iron, Pb is lead, Mg is magnesium, Al is aluminum, O is oxygen, N is nitrogen, and H is hydrogen.
What is the Chemical composition of battery?
the positive plate is Pb the negative is PbO2 and the acid is H2SO4.
