HELP PLZ ITS DUE IN 10 MIN "Jack's model includes one object consisting of two molecules and one object consisting of six molecules. He put 16 energy cubes in each object and stated that his model showed the two objects at equilibrium. Explain what is wrong with Jack's model."

(I know it looks long but basically I just need help with finding what's wrong with the model)

Answers

Answer 1

Answer: the molecules have different energy and the system is not in equilibrium

Explanation:

The model developed by Jack has the same energy for each of the two objects, but as each object is made up of a different number of molecules, in the system with more molecules, object 2, each one has approximately 2.4 less energy and the molecules of Object 1 have an E / 2 energy.

So when you book them together the molecules have different energy and the system is not in equilibrium

Answer 2

Jack presented the model as if the two objects were in energy balance, but this is not possible, as each object has a different number of molecules.

We can arrive at this answer because:

For the system presented in Jack's model to be in energetic balance, it would be necessary for the two objects present in the model to have the same number of molecules.This is because, with equal amounts of molecules, each object would be able to emit the same amount of energy.However, the object with fewer molecules tends to emit less energy than the object with more molecules.

This allows for an uneven, unbalanced emission of energy in the system and this unevenness is not presented in Jack's model.

Are two clear liquids mix to create a “chunky” solid a chemical of physical change? Why?

Answer:

Well i know that a chemical change is somthing that can not be undone.

This however is a physical change let me explain.

Even though you mixed two chemicals together to create a new substance does NOT mean it is a chemical change. This however is kinda like a water. You can turn water into a ice cube that does not mean it changed what the water is made out of it just changed the form of the water. Kinda like this. A chemical change would be an example of buring a log once that log has turned into ashs it will never be the log it was before.

what is the density of a small block of wood with a mass of 35g and a volume of 70 cm3

Help plz

Answers

Answer:

The density of the wood is 0.5 g/cm³

Explanation:

To calculate density you need to use the formula D = M/V

D = Density

M = Mass (in grams)

V = Volume (in cm³ for solids and mL for liquids)

So, just plug in your given values: D = 35 g ÷ 70 cm³ = 0.5 g/cm³

Voila, you just calculated the density of that piece of wood!

Answers

Answer:

i only found the 49, hope it still helps, mate

49. In this question (t½) of C-14 is 5730 years, which means that after 5730 years half of the sample would have decayed and half would be left as it is.

After 5730 years ( first half life) 70 /2 = 35 mg decays and 35 g remains left.

After another 5730 years ( two half lives or 11460 years) 35 /2 = 17.5mg decays and 17.5 g remains left .

After another 5730 years ( three half lives or 17190 years) 17.5 /2 = 8.75mg decays and 8.75g remains left.

after three half lives or 17190 years, 8.75 g of C-14 will be left.

Explanation:

Earth's rotation affect ocean currents because: A. It causes them to flow in a curved path.

What is Earth rotation?

Earth rotation can be defined as the amount of time that is taken by planet Earth to complete its spinning movement about an orbital axis.

This ultimately implies that, Earth rotation refers to the time taken by earth to rotate once on its axis. Also, a spinning movement of the Earth on its axis takes approximately 24 hours to complete with respect to the Sun and it result in an effect called Coriolis.

In conclusion, Earth's rotation affect ocean currents because it causes them to flow in a curved path due to Coriolis effect.

Show how the limiting reactant is determined for 3.80 g of magnesium reacting with 12.5 g of oxygen.

Answers

Answer:

Magnesium is the limiting reactant.

Explanation:

The balanced reaction is:

2 Mg + O₂ ⇒ 2 MgO

By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following quantities participate in the reaction:

Mg: 2 molesO₂: 1 moleMgO: 2 moles

Being the molar mass:

Mg: 24.31 g/moleO₂: 32 g/moleMgO: 40.31 g/mole

Then the following quantities of mass participate in the reaction:

Mg: 2 moles* 24.31 g/mole= 48.62 gO₂: 1 mole* 32 g/mole= 32 gMgO: 2 moles* 40.31 g/mole= 80.62 g

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

To determine the limiting reagent, it is possible to use the reaction stoichiometry of the reaction. You can use a simple rule of three as follows: If by stoichiometry of the reaction 32 grams of oxygen react with 48.62 grams of magnesium, 12.5 g of oxygen will act with how much mass of magnesium?

[tex]mass of magnesium=\frac{12.5 g of oxygen*48.62 grams of magnesium}{32 grams of oxygen}[/tex]

mass of magnesium= 18.99 grams

But 18.99 grams of magnesium are not available, 3.80 molesgrams are available. Since you have less mass than you need to react with 12.5 grams of oxygen, magnesium will be the limiting reagent.
