The diagrams below show interactions between charged particles. The blue particles are negatively charged, and the red particles
are positively charged.
Which of the diagrams shows a correct interaction between the fields of two charged particles?

Answer:

Temperature does not change, remains 264 K

Given

V₁= 1.2 L

P₁ = 1.8 atm

T₁ = 264

Required

The new temperature

Solution

The volume was doubled = 2V₁ = 2 x 1.2 = 2.4 L(V2)

The pressure was halved = 0.5P₁ = 0.5 x 1.8 = 0.9 atm(P2)

Combined gas law :

P₁V₁/T₁=P₂V₂/T₂

Input the value :

[tex]\tt \dfrac{1.8\times 1.2}{264}=\dfrac{0.9\times 2.4}{T_2}\\\\T_2=264[/tex]

Answer: [tex]1s^22s^22p^63s^23p^64s^2[/tex] , oxidation state = +2

Explanation:

Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom. The electrons are filled according to Afbau's rule in order of increasing energies.

The electronic configuartion of Calcium with atomic number 20  is :

[tex]Ca:20:1s^22s^22p^63s^23p^64s^2[/tex]

As calcium can easily lose its two valence electrons to attain stability , its oxidation state is +2.

[tex]Ca^{2+}:18:1s^22s^22p^63s^23p^6[/tex]

Answer:

They represent the valence electrons, so s and p sublevels only! This does not include the d block!

Answer:

C. Water has a greater density than alcohol.

Explanation:

From the experiment, it can be shown that water has a greater density than the alcohol.

The ice cube is able to float in the water because, the density of the ice is less than the density of the water.

 Density of ice < Density of water

So, the ice cube sinks in alcohol because the density of the ice cube is greater than the density of the alcohol.

 Density of ice > Density of alcohol

Therefore, we can assume that since the density of ice is greater than density of alcohol, then the density of water is greater than that of the alcohol.

Answer:

[tex]\boxed {\boxed {\sf 0.6692 \ mol \ AlCl_3}}[/tex]

Explanation:

To convert from grams to moles, we must use the molar mass. This can be calculated using the Periodic Table.

1. Molar Mass

First, identify the elements in the compound AlCl₃. They are aluminum and chlorine. Now find the masses:

Take a look at the compound. There is a subscript of 3 after chlorine, so we must multiply its molar mass by 3 then add aluminum's.

2. Convert Grams to Moles

We can use the molar mass as a ratio.

[tex]\frac{133.331538 \ g \ AlCl_3}{1 \ mol \ AlCl_3}[/tex]

Multiply by the given number of grams: 89.23

[tex]89.23 \ g \ AlCl_3 * \frac{133.331538 \ g \ AlCl_3}{1 \ mol \ AlCl_3}[/tex]

Flip the fraction so the grams of aluminum chloride cancel out.

[tex]89.23 \ g \ AlCl_3 * \frac{1 \ mol \ AlCl_3}{133.331538 \ g \ AlCl_3} = 89.23 \ * \frac{1 \ mol \ AlCl_3}{133.331538}[/tex]

[tex]\frac{89.23 \ mol \ AlCl_3}{133.331538}[/tex]

[tex]0.6692340112 \ mol \ AlCl_3[/tex]

3. Round

The original measurement of grams has 4 significant figures. We must round to 4 sig figs.

For the number we calculated, that is the ten thousandth place.

The 3 in the hundred thousandth place tells us to leave the 2.

[tex]0.6692 \ mol \ AlCl_3[/tex]

There are about 0.6692 moles of aluminum chloride in 89.23 grams.

According to the stoichiometry of the given chemical equation, 13.9939 grams of NaOH would be made with 8.0465 g of Na.

Stoichiometry is the determination of proportions of elements or compounds in a chemical reaction. The related relations are based on law of conservation of mass and law of combining weights and volumes.

Stoichiometry is used in quantitative analysis for measuring concentrations of substances present in the sample. It is useful in balancing chemical equations and making solutions of different concentrations.As according to the given chemical equation 46 g sodium gives 80 g sodium hydroxide, thus,  8.0465 g of sodium will give 8.0465×80/46=13.9939 grams.

Thus, 13.9939 grams of NaOH would be made with 8.0465 g of Na.

Answer:

thermal

Explanation:

Thermal energy is due to the motion of an object's particles, due to the random movement of molecules in a system, thermal energy also known as random or internal kinetic energy is produced, hence option A is correct.

Atoms or molecules in motion are the source of thermal energy. An object's thermal energy rises as its temperature rises because the movement of its molecules or atoms accelerates. It is possible to transmit an object's thermal energy to another.

Thermal energy, also known as random or internal kinetic energy, is created when molecules in a system move randomly, as a result of the motion of an object's particles.

The substance with the greatest molecular mass is I₂.

The molecular mass is the sum of the atomic masses of all atoms in a molecule

Let's calculate the molecular mass of each compound to know the greatest.

molecular mass of H₂O₂ = 2 + 32 = 34 g/mol

molecular mass of CF₄ = 12 + (19 × 4) = 12 + 76 = 88 g/mol

molecular mass of NO = 14 + 16  = 30 g / mol

molecular mass of I₂ = 127 × 2 = 254 g/mol

Therefore, the substance with the greatest molecular mass is I₂.
