ANSWER
empirical formula is the simplest ratio of whole numbers of components making up a compound
molecular formula is the actual composition of components making up a compound
to analyse each statement
A.They are always different for the same compound. -
the empirical formula in some instances can be the same as the molecular formula. therefore this statement is incorrect.
B. Subscripts of empirical formulas can be reduced
empirical formula gives the simplest ratios and the subscripts cannnot be further simplified therefore this is incorrect
C. Molecular formulas can be determined from empirical formulas
using the empirical formula, the molecular formula can be determined. therefore its correct.
D. They both show the actual ratio of elements for a compound
only the molecular formula gives the actual ratio of elements whereas the empirical formula gives the simplest ratio of elements. this statement is incorrect
The correct statement is C.
Answer:
Molecular formulas can be determined from empirical formulas.

Answer:
D. Something that pushes the experimental results one way or another
Explanation:
Bias is the tendency of a measurement or outcome to be consistently different from what it would be if all preconceived notions or irrelevant influences were removed. It pushes experimental results one way or another.

The three primary sources of carbon dioxide (CO2) in the atmosphere are the respiration of organisms, the burning of fossil fuels, and deforestation or land use changes.
Carbon dioxide (CO2) is a type of gas that naturally exists in the atmosphere. It is primarily released from three key sources, which include:
The three primary sources of carbon dioxide (CO2) in the atmosphere are the respiration of organisms, the burning of fossil fuels, and deforestation or land use changes.
The three primary sources of carbon dioxide (CO2) in the atmosphere are the respiration of organisms, the burning of fossil fuels, and deforestation or land use changes.
Yet due to human activities like industrialization and deforestation, the amounts of CO2 in the atmosphere have been increasing at an unprecedented rate, leading to global climate change.

A.grouping A.Similar element names
B.families B.Similar properties
C.periods C.Similar symbols
D.lines D.Similar masses
Vertical columns on the periodic table are called B. families.
The elements in each column, or family, have B. Similar properties.
In the periodic table, elements are organized into rows and columns based on their atomic number and electron configuration. Each vertical column represents a family or group of elements that share similar chemical and physical properties.
The elements within a family tend to have similar valence electron configurations, leading to similar chemical behaviors and reactivity patterns.

b.)the pressure will decrease c.) the pressure will increase d.) the density will decrease
The pressure will increase. The correct option is (C).
The most reasonable change in property to expect when the volume of the gas is reduced is the pressure will increase.
This relationship between pressure and volume is described by Boyle's law, which states that when the volume of a gas decreases at constant temperature, the pressure of the gas increases.
This is because reducing the volume of the chamber decreases the space available for the gas particles to move, leading to more frequent collisions with the walls and an increase in pressure.
Therefore, as the volume of the gas is reduced in the chamber, the pressure will increase.

Answer:
Among the different types of scientific knowledge hypotheses are likely to be modified or discarded most frequently. Long ago in the 1600's scientists discarded the phlogiston theory because the new evidence didnt support it.
Explanation:
Hypothesis is the assumption of something possible or impossible to draw a consequence and is provisionally established as the basis for an investigation and which can confirm or deny its validity. For this reason, within scientific research, hypotheses are so important and so changeable that they are modified or discarded more frequently within scientific knowledge.
Based on a work by Johann Joachim Becher, the German scientist Georg Ernst Stahl created the phlogiston theory that said combustion occurred with certain materials because they had an “element” or a common flammable principle that was released at the time of burning . This theory was abandoned because there was no evidence, even through scientific experiments, to prove that this theory is true.
Hypotheses are likely to be modified or discarded most frequently in scientific knowledge. Phlogiston theory was discarded due to evidence contradicting its predictions.
Among the different types of scientific knowledge, hypotheses are likely to be modified or discarded most frequently. Long ago, in the 1600s, scientists discarded the phlogiston theory because evidence contradicted the predictions made by the theory. Phlogiston theory proposed that a substance called phlogiston was released during combustion, but experiments showed that substances gained weight instead of losing weight during combustion.
