How does a conclusion differ from an inference?
Setler79 [48]

Answer:

the difference between the two. Inference: Inference is something that uses facts to determine other facts. ... Inference can be accurate or inaccurate, justified or unjustified, logical or illogical. Conclusion: A conclusion is the next logical step in the information series.

Explanation:

Inferences and conclusions from that analysis can be powerful tools for understanding people and the decisions that they make. An inference is an assumed fact based on available information. A drawn conclusion is an assumption developed as a next logical step for the given information.

The reaction of Fe3O4(s) with hydrogen(g) to form iron(s) and water(g) proceeds as follows: Fe3O4(s) + 4 H2(g) 3 Fe(s) + 4 H2O(g
Reptile [31]

Answer:  151 kJ

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}  

\text{Moles of} Fe_3O_4=\frac{61.8g}{231.5g/mol}=0.267moles

Fe_3O_4(s)+4H_2(g)\rightarrow 3Fe(s)+4H_2O(g)

It is given that:

0.267 moles of Fe_3O_4 absorb energy = 40.3 kJ

Thus 1 mole of Fe_3O_4 absorb energy =\frac{40.3}{0.267}\times 1=151kJ  

Thus the value of \Delta H for the chemical equation given is 151 kJ

Mercury-203 undergoes beta minus decay. 203 80 hg → 203 81 tl ? the subatomic particle produced is a(n) . 203 80 hg → 203 81 tl
cricket20 [7]

The correct balanced equation of a beta decay undergone by Mercury-203 is as follows:

203 80 Hg → 203 81 + 0 -1 e

<h3>What is beta decay?</h3>

Beta decay in radioactivity refers to the release of a beta particle by a radioactive element.

Beta particle is characterized by the possession of mass number 0 and atomic number -1.

This means that if Mercury-203 undergoes beta decay, the atomic number of the resulting isotope will be +1 as follows:

203 80 Hg → 203 81 Tl + 0 -1 e
