Answer:
There are 8 valence electrons in an argon atom.
45 kilometers
He was driving 90km/hr and it only took half an hour.
half of 90 is 45
The answer is C4H10. The work is kinda mess so ya
Na₂CrO₄ + PbCl₂ → PbCrO₄ + 2 NaCl
<u>Explanation:</u>
In a double displacement reaction, the reactants which are involved in the reaction exchanging their ions thereby produces 2 new compounds. Here sodium chromate and lead chloride are undergoing double displacement reaction, the ions exchanges their position there by forming sodium chloride and lead chromate. So the double displacement reaction is given as,
Na₂CrO₄ + PbCl₂ → PbCrO₄ + 2 NaCl
Can you post another picture its not really showing anything
