Answer:
8. C. CH4 (g) + 202(gl) = CO2g (g) + 2H20 (g)
9. D. CaCO3(s) + 2 HCl(aq) = CaCl2(aq) + CO2(g) + H2O(l)
Explanation:
balance niyo po lahat gamit ang algebraic method.
hanapin niyo if may variable (example of no. 8 please do the same of no.9)
-aCH4(G) + bO2(G) = cCO2(G) + dH2O(G)
Create a System Equation (first letter of elements po)
C: 1a + 0b = 1c + 0d
H: 4a + 0b = 0c + 2d
G: 1a + 1b = 1c + 1d
O: 0a + 2b = 2c + 1d
Pagkatapos niyong mag-solve sa variables, Simplify the results from lowest to whole.
a = 1 (CH4(G))
b = 2 (O2(G))
c = 1 (CO2(G))
d = 2 (H2O(G))
Substitute Coefficients and Verify Result
Substitute Coefficients and Verify ResultCH4(G) + 2O2(G) = CO2(G) + 2H2O(G)
kapag equal lahat ng numbers pag verify niyo, correct yung answer.
