Answer:
The endpoint volume is 50.52 ± 0.14 mL
Explanation:
In a titration always is necessary to subtract the blank volume to the titrant volume to obtain the real volume of the titrant. Thus in this case, the total endpoint volume is the sum of the initial volume delivered and the second volume delivered, minus the blank volume:
V = (49.16±0.06 mL) + (1.69±0.04 mL) - (0.33±0.04 mL)
V = (49.16 + 1.69 - 0.33) ± (0.06+0.04+0.04) mL
V = 50.52 ± 0.14 mL
It is necessary to consider the sum of the errors too.
"equal to"
1=1
1 is equal to 1
Is this what you mean?
Answer:
b is the answer
Explanation:
non metals are not shiny, brittle, unmalleable, and are poor conductors of thermal energy and electrical current.
It's either B or D because there would be 2 coefficients of hydrogen and one of oxygen
