Answer:
B. The data were reproduced by other scientists using the same experimental methods.
Explanation:
One of the features of reliable experimental results is their reproducibility — other scientists must be able to produce them.
A. is wrong. An experiment that is designed to prove a hypothesis is biased.
C. is wrong. A conclusion based on a single experiment is suggestive but not conclusive. It takes a number of experiments to provide a strong statistical relation between the variables.
D. is wrong. The data may support a conclusion that the they reached using logic and critical thinking, but there may still be a flaw in the thinking, which other scientists can point out.
Yes metamorphic rocks melt in hot fluid
Answer: 0.00488K
Explanation: using the general gas equation
(P1V1)/T1 =(P2V2)/T1
Substitute
2*6/273= 3*3/T
Simplify
T= 0.00488°K
O3 + M2+(aq) + H2O(l) => O2(g) + MO2(s) + 2 H+
Eo(cell) = Eo(O3/O2) - Eo(MO2/M2+)
0.44 = 2.07 - Eo(MO2/M2+)
Eo(MO2/M2+) = 1.59 V
