During an investigation, a scientist burned 48 g of magnesium strip. After the reaction, the total mass of the product formed was found to be 80 g. Does the law of conservation of mass hold true in this case? Use complete sentences to justify your answer based on numerical calculations.

Answers

Answer

yes

Explanation:

the law of conservation of mass hold true in this case burning magnesium strip is explained by this equation 2 Mg (s) + O2 (g) -> MgO (s)So the lighter magnesium, after reacting with oxygen in air, forms the heavier magnesium oxide. molar mass of magnesium and magnesium oxide are 24g and 40g respectively. So the same ratio 24:40 (i.e. 3:5) is maintained in the given masses of 48g and 80g, which means mass is conserved in the reacion.

What happened when the two substances were combined together in the cup? (highlight one)
The substances changed into different substances.
The substances did not change into different substances.
I am not sure if the substances changed into different substances.
Explain your answer using evidence from the Sim.

Answers

Based on evidence from Sim, when two substances were combined they did not change into different substances.

Here the word Sim is used to describe the process simulation. Simulation is defined as when two substances combined they do not change into different substances.

They just combine together and form a new substance.

Let us understand it as the first substance is liquid and the second substance is solid then when we combine both of them they form a new mixture but do not change their property.

The mixture is still liquid but it also has some properties of solid substance.

The substances did not change into different substances.

Based on the information provided in the question, there is no evidence or indication of any chemical reaction or change in the substances when they were combined in the cup. The question does not mention any observations or effects that would suggest a chemical transformation.

If there were a chemical reaction or change, it would typically be accompanied by observable signs such as color change, gas production, temperature change, or formation of a precipitate. However, since the question does not provide any evidence or observations of such changes, we can conclude that the substances did not undergo any chemical transformation when combined.

It is important to note that without additional information or details about the substances and their behavior, it is not possible to make definitive conclusions. However, based on the given information, the most reasonable conclusion is that the substances remained unchanged when combined in the cup.

Understory Layer

Located several meters below the canopy, the understory is an even darker, stiller, and more humid environment. Plants here, such as palms and philodendrons, are much shorter and have larger leaves than plants that dominate the canopy. Understory plants’ large leaves catch the minimal sunlight reaching beyond the dense canopy.

Which process involves informal investigations done by native peoples as they use nature to meet their needs?(1 point) discovery discovery reverse engineering reverse engineering trial and error trial and error native science

Answers

The scientific method is an empirical method of acquiring knowledge that has characterized the development of science since at least the 17th century (with notable practitioners in previous centuries). It involves careful observation, applying rigorous skepticism about what is observed, given that cognitive assumptions can distort how one interprets the observation. It involves formulating hypotheses, via induction, based on such observations; experimental and measurement-based testing of deductions drawn from the hypotheses; and refinement (or elimination) of the hypotheses based on the experimental findings. These are principles of the scientific method, as distinguished from a definitive series of steps applicable to all scientific enterprises.

Discovery is the process involves informal investigations done by native peoples as they use nature to meet their needs.

What do you understand by Science ?

Science is the pursuit and application of knowledge and understanding of the natural and social world following a systematic methodology based on evidence.

The process, including informal investigations by indigenous peoples to meet their needs, is the  discovery of indigenous sciences.

These are currently being adopted to meet people's needs and helped to provide new ideas and aspects for climate change, specific animal population declines, and sustainable harvesting practices.

Therefore Option 1 is the correct answer.
