Answer: chemical weathering
Explanation: Chemical weathering is different from mechanical weathering because the rock changes, not just in size of pieces, but in composition. That is, one type of mineral changes into a different mineral. Chemical weathering works through chemical reactions that cause changes in the minerals.
Idk good luck it’s one of these choices
Answer: He theorized that all material bodies are made up of indivisibly small “atoms.” Aristotle famously rejected atomism in On Generation and Corruption. Aristotle refused to believe that the whole of reality is reducible to a system of atoms.
Explanation:
Answer:
Let's do it like this...
The question says write a balanced equation for the reaction between aqueous lead(II) nitrite and aqueous potassium chloride to form solid lead(II) chloride and aqueous potassium nitrite...
Analysising
________________________________________________________
Aqueous Lead(II) Nitrate written as a Formula is Pb(NO3)2 and Aqueous potassium written as a Formula is KOH.......and.......here the statement says they form Solid lead(ll) chloride which is PbCl₂ and aqueous potassium nitrite which is KNOH3
so The unbalanced equation will be
Pb(NO3)2 + KCL ====> PbCl2 + KNOH3
________________________________________________________
New Balanced Equation
________________________________________________________
Pb(NO3)2 + 2KCL ====> PbCl2 + 2KNOH3
(Balanced) RHS = LHS
Explanation:
Balancing The Equation
Lead (Pb) Has a coefficient of 1 both side.(Balanced)
Nitrate (NO3) has 2 as their coefficient both sides. (balanced)
Potassium (K) has a coefficient of 2 in the left so in the right. (balanced)
Chlorine (Cl) has also a coefficient of 2 in the right so in the left. (balanced)
Therefore the equation is balance the LHS equals to the RHS
NB : There's no any balanced equation than this
BaSO₄(s) ⇄ Ba²⁺(aq) + SO₄²⁻(aq)
Ksp=[Ba²⁺][SO₄²⁻]
[Ba²⁺]=[SO₄²⁻]
Ksp=[Ba²⁺]²
Ksp=(1.76*10⁻³)² =3.0976×10⁻⁶ ≈3.1×10⁻⁶
