Answer:
a model?
Explanation:
im not sure! i think so
Answer:
Yes, It is a model
Explanation:
A complex idea or a process can be demonstarated by using a Model because you can see things easier and its basically a copy of anything from forests to volcanoes but smaller to make it easier to see.

Juan measures a piece of metal and determines it has a mass of 10 grams and a volume of 2 ml
What is the density of the piece of metal?
Answer:
The answer is 5.0 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 10 g
volume = 2 mL
We have
[tex]density = \frac{10}{2} \\ [/tex]
We have the final answer as
5.0 g/mLHope this helps you
Answer:
5.0 g/mL

Students want to gather evidence for the claim that the number of atoms present before a chemical reaction is equal to the number of atoms present after the chemical reaction. They decide to react vinegar and baking soda in a sealed plastic bag. Which of the following would provide evidence the students need
Answer:
The mass of the plastic bag, baking soda, and vinegar before the reaction was equal to the mass after the reaction.
Explanation:
The two main postulates that was given by Antoine Lavoisier are, oxygen play an important role in combustion and the other is mass of the reactant and product is conserved. Therefore, the reaction shows the law of conservation of mass.
What is law of conservation of mass?According to Law of conservation of mass, mass can neither be created nor be destroyed. Mass can only be transformed from one form to another. The law of conservation of mass was given by Antoine Lavoisier.
Every reaction in nature follow the law given by Antoine Lavoisier that is mass is always conserved. The mass of the plastic bag, baking soda, and vinegar before the reaction was equal to the mass after the reaction.
Therefore, the reaction shows the law of conservation of mass.

The reaction between methanol and oxygen gas produces water vapor and carbon dioxide. 2CH3OH(l)+3O2(g)⟶4H2O(g)+2CO2(g) Three sealed flasks contain different amounts of methanol and oxygen. Based on the molecular view of the three flasks, which would produce the largest quantity of total product? The flask contains 3 molecules of C H 3 O H and 3 molecules of O 2. The flask contains 1 molecule of C H 3 O H and 6 molecules of O 2. The flask contains 4 molecules of C H 3 O H and 2 molecule of O 2. For the flask which produces the largest quantity of total product, how many molecules of H2O will be formed? molecules of H2O :
Answer:
The flask that produces the largest quantity of product is the second flask
The molecules of H 2 O formed is [tex]X = 8 \ molecules [/tex]
Explanation:
From the question we are told that
The reaction is
2CH3OH(l) + 3O2(g)⟶4H2O(g)+2CO2(g)
The first flask contains 3 molecules of C H 3 O H and 3 molecules of O 2
The second flask contains 1 molecule of C H 3 O H and 6 molecules of O 2
The third flask contains 4 molecules of C H 3 O H and 2 molecule of O 2.
Looking at the three flasks we can see that base on molecular view the flask which produces the largest quantity of total product is second flask
From the balanced equation we see that 2 moles of C H 3 O H are required to react with 3 moles of oxygen hence O 2 is the limiting reactant
Generally 1 mole of any substance is [tex]1 * N_A[/tex] of that substance
Here [tex]N_A[/tex] is the Avogadro number with the value [tex]N_A = 6.02214076 * 10^{23} \ molecules[/tex]
So
Looking at the balanced equation we see that 3 moles of O 2 (3 * [tex]N_A[/tex] molecules of O 2 ) produces 4 moles of H2O(4 *
Then 6 molecules of O 2 will produce X molecules of H 2 O
So
[tex]X = \frac{6 * (4 * N_A }{3 * N_A}[/tex]
=> [tex]X = 8 \ molecules [/tex]
