Na₂C₂O₄(aq) + Pb(NO₃)₂⇒PbC₂O₄(s) + 2NaNO₃(aq)
<h3>Further explanation</h3>
Given
Word equation
Required
Balanced equation
Solution
Convert to skeleton equation
Na₂C₂O₄(aq) + Pb(NO₃)₂⇒PbC₂O₄(s) + NaNO₃(aq)
Balanced equation
Give a coefficient
Na₂C₂O₄(aq) + aPb(NO₃)₂⇒bPbC₂O₄(s) + cNaNO₃(aq)
Make an equation
C, left = 2, right =2b⇒2b=2⇒b=1
Na, left = 2, right = c⇒c=2
O, left = 4+6a, right = 4b+3c⇒4+6a=4b+3c⇒4+6a=4.1+3.2⇒6a=6⇒a=1
The equation becomes :
Na₂C₂O₄(aq) + Pb(NO₃)₂⇒PbC₂O₄(s) + 2NaNO₃(aq)
Answer:
HF + H₂O ⇔ H₃O⁺ + F⁻
Explanation:
Bronsted- Lowery acid:
Bronsted- lowery acid is the specie which have capability to donate the proton.
Bronsted- Lowery conjugate base:
The Bronsted- Lowery conjugate base of Bronsted- Lowery acid is the specie which is formed after when an acid donate the proton.
Bronsted- Lowery base:
Bronsted- lowery base is the specie which have capability to accept the proton.
Bronsted- Lowery conjugate acid:
The Bronsted- Lowery conjugate acid of Bronsted- Lowery base is the specie which is formed after when an base accept the proton.
Chemical equation:
HF + H₂O ⇔ H₃O⁺ + F⁻
In this equation HF is acted as Bronsted- Lowery acid because it donate the proton to water. water is act as Bronsted- Lowery base. While F⁻ is the Bronsted- Lowery base and H₃O⁺ Bronsted- Lowery acid.
Answer:
A. LST
Explanation:
• 1st Law: The path of each planet around the Sun is an ellipse with the Sun at one focus.
• 2nd Law: The line from the Sun to any planet sweeps out equal areas of space in equal time intervals.
• 3rd Law: The square of the orbital period of a planet is directly proportional to the cube of the average distance
Answer:
mineral acids are obtained from one or more inorganic compounds which is a compound that lacks carbon and hydrogen bonds. Inorganic compound examples include water and carbon dioxide. Something all mineral acids do is form hydrogen ions and the joined together bases when it is dissolved in water.
