a.uses of functional groups involving oxygen
Answer:
4.3043x10^24
Explanation:
Atoms(H) = (3.575 mol H2S/1)(2 mol H/1mol H2S)(6.02x10^23/1molH)
Simple stoicheometry problem. Sorry for taking so long, took Chem sophomore year, its been a while
The answer is A. Liquid Oxygen
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)
