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.
Answer:
Explanation:
1. It is not Blanced. on the right the is 1S and 6O and the left there is 1S and 3O
2.If the energy level of the reactants is higher than the energy level of the products the reaction is exothermic (energy has been released during the reaction). If the energy level of the products is higher than the energy level of the reactants it is an endothermic reaction.
I think it's C. Please mark brainliest
Answer:
5 moles of Fe(II) are required to react completely with the 5 moles of Sulphur
Explanation:
The balanced equation in this question is
Iron + Sulfur = Iron(II) Sulfide
Fe (II) + S --> Fe(II)S
Thus one mole of sulfur reacts with one mole of Fe(II)
Hence, 5 moles of Fe(II) are required to react completely with the 5 moles of Sulphur
