Answer:

No, I don't think so at least

Which statement best describes a typical difference that could be found between the "Analysis" and "Conclusion" sections of a
IgorC [24]

The statement “Only the “Conclusion” section discusses whether the original hypothesis was supported, and both sections suggest further  research”, best describes the difference between analysis and conclusion.

Answer: Option 4

<u>Explanation: </u>

In research, we do experiments and derive the results. Then, those results were analyzed by us. In this analysis part, we compare our results with the related results published elsewhere. Also, we correlate the similarities and point out the differences between our analysis and other reported results.

In conclusion part, we have to check hypothesis or it supported. And, we summarise our analysis and figure out the further research need to be done on that to improvise our research. So, the final statement is the correct option which best describes the difference between analysis and conclusion.

A log has a density of .8 g/cm³. What will happen to this log in freshwater, which has a density of 1.0 g/cm³?
Inga [223]

Answer:

The log will float on the water because its density is lower than the liquid, so it will stay at the top due to Archimedes' principle.

An ancient silver coin has a density of 10.49 g/cm3 at 20°C. If you break the coin that weighs 4.001 in half
Wittaler [7]

The density of each half of the coin is 10.49 g/cm3

In science density is defined as the ratio of mass to volume of an object.

Density is an intrinsic property.It is not affect by the amount of substance present.

This implies that each half of the broken coin must have the same density since it it is an inherent property of every silver material.

The density of each part of the coin therefore is  10.49 g/cm3.

Teniendo en cuenta los siguientes fenómenos: ebullición del agua- movimiento de un cuerpo- disolución de sal en agua- combustión
miv72 [106K]

Answer:

Las siguientes son reacciones químicas;

combustión de leña

oxidación del hierro

descomposición del agua en hidrógeno y oxígeno

Explanation:

Una reacción química da como resultado la formación de una (s) sustancia (s) nueva (s), mientras que un cambio físico no conduce a la formación de una sustancia nueva.

Las siguientes son reacciones químicas;

combustión de leña: la combustión de madera implica la oxidación del carbono según la reacción; C (s) + O2 (g) -------> CO2 (g)

oxidación del hierro: La oxidación del hierro conduce a la formación de óxidos de hierro. Como; 2Fe (s) + O2 (g) ----> 2FeO (s)

descomposición del agua en hidrógeno y oxígeno: esta es una reacción química en la que el agua se descompone de la siguiente manera; 2H2O (l) -----> 2H2 (g) + O2 (g)

Todos estos procesos enumerados anteriormente conducen a la formación de nuevas sustancias, por lo tanto, son reacciones químicas.
