A student Hatfields a jar with rice and take Insta jars lids the student wants to use a jar of rice to model particle motion of

a substance in any state of matter
Chemistry
1 answer:
Sliva [168]2 years ago
8 0

Answer and Explanation:

The student can use the half rice pot to model the movement of the particles of the material. For this it is necessary that he research the spatial arrangement of the molecules in a solid material, a liquid and a gas.

In this research, he will find that the molecules in a solid material are positioned very close to each other, not allowing any of them to move. In this case, he can pass the grain of hoops to a smaller pot, which is completely filled by the grains. When shuffling the pot, the boy will see that the rice grains do not move and assuming that each grain represents a molecule of the material, he will notice that the molecules in a solid material do not move.

The research will show that the molecules of a liquid material are a little more distant from each other than the molecules of solid materials. However, this distance is not very long, allowing these molecules to be able to touch each other when they are in motion. To visualize this with the rice grains, the student must remove some grains from the jar and allow a certain space between one grain and another.

The molecules of a gaseous material are very far apart. These molecules have access to full movement and rarely touch each other. To visualize this, the student must remove many grains of rice from the pot, leaving it almost empty and watching the movement of the remaining grains.

Calculate a reasonable amount (mass in g) of your unknown acid to use for a titration. You will want about 30 mL of titrant to g
Vinil7 [7]

Answer:

"0.60 g" is the appropriate solution.

Explanation:

The given values are:

Volume of base,

= 30 ml

Molarity of base,

= 0.05 m

Molar mass of acid,

= 400 g/mol

As we know,

⇒  Molarity=\frac{Number \ of \ moles \ of \ base}{Number \ of \ solution}

On substituting the values, we get

⇒           0.05=\frac{Number \ of \ moles \ of \ base}{30\times 10^{-3}}

⇒  Number \ of \ moles \ of \ base=0.05\times 30\times 10^{-3}

⇒                                             =1.5\times 10^{-3}  

hence,

⇒  Moles \ of \ acid=\frac{Mass \ of \ acid}{Molar \ mass \ of \ acid}

On substituting the values, we get

⇒  1.5\times 10^{-3}=\frac{Mass \ of \ acid}{400}

⇒  Mass \ of \ acid=1.5\times 10^{-3}\times 400

⇒                         =0.60 \ g

Which equation demonstrates that nuclear fusion forms elements that are heavier than helium
GrogVix [38]

Answer: The correct option is 2.

Explanation: There are two types of nuclear reactions:

1) Nuclear fission: These reactions are defined as the reactions in which a heavier unstable nuclei breaks into two or more smaller stable nuclei.

2) Nuclear fusion: These reactions are the ones where two smaller nuclei fuse together or combine together to form a larger nuclei.

In the question, we need to find the fusion reaction which forms elements heavier than helium.

Option 1: In this fusion reaction occurs but the nuclei is Helium itself.

Option 2: In this also fusion reaction occurs and the nuclei is heavier than Helium which is Neon.

_8^{16}\textrm{O}+_2^4\textrm{He}\rightarrow _{10}^{20}\textrm{Ne}

Option 3 and Option 4: These two reactions are nuclear fission reactions of Uranium-235 because one heavier element is breaking into more than 2 products.

Hence, the correct option is 2.

Mass = 35g Volume = 7cm³ What is the Density?​
gizmo_the_mogwai [7]

Answer:

The answer is

<h2>5.0 g/cm³</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question

mass = 35 g

volume = 7 cm³

The density is

density =  \frac{35}{7}  \\

We have the final answer as

<h3>5.0 g/cm³</h3>

Hope this helps you
