Model A is better than Model B as Model A shows the three-dimensional shape of the molecule, but Model B does not. The correct option is c.

What are molecules?

The smallest particle of a substance possesses all of its physical and chemical properties. One or more atoms make up a molecule.

Knowing the molecular weights of the molecules allows us to calculate their sizes. The molecular weight of a molecule is the sum of the atomic weights of the atoms in the molecule.

The relative atomic mass of particles determines their size. Particles with a higher relative atomic mass weigh more than particles with a lower relative atomic mass. Larger atoms have heavier iotas and a larger relative atomic mass.

Therefore, the correct option is c, Model A shows the three-dimensional shape of the molecule, but Model B does not.

b. The nucleus is made of protons, electrons, and neutrons.
c. Electrons are distributed around the nucleus and occupy almost all the volume of
the atom.
d. The nucleus is made of electrons and protons.

Answers

Answer:

B

Explanation:

The neucles is surrounded by electrons. Electrons occupy most of the volume of the atom.

Atomic Model:

Atoms are the smallest unit of elements, which form bonds with others. In an atom, electrons revolve around the nucleus.

The nucleus is composed of positively charged protons and neutrons. The nucleus occupies a very small part of the atom.

Electrons are negatively charged particles, they are found around the nucleus and occupy most of the part of the atom.

Therefore, The neucles is surrounded by electrons. Electrons occupy most of the volume of the atom.

How many moles are there in 32.4 grams of Na

Answers

Divide that my the molar mass which is 23 so 1.4087 g

According to the mole concept, there are 1.4087 moles in 32.4 grams of sodium.

What is a mole?

Mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.

It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.

It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons. Molar mass has units of gram per mole . In case of molecules, where molar mass  in grams present in one mole  of atoms is its atomic mass.

Number of moles in this case is obtained by dividing mass by molar mass that is, 32.4/23=1.4087 moles.

Thus, there are 1.4087 moles in 32.4 g of sodium.

B) decomposition
C) synthesis
D) single replacement

Answers

Answer:

A) double replacement

Explanation:

Chemical equation:

NaCl +CaS    →    Na₂S + CaCl₂

Balanced chemical equation:

2NaCl +CaS    →    Na₂S + CaCl₂

The given reaction is double replacement reaction in which cation and anions of each reactant exchange with each other.

Double replacement:

It is the reaction in which two compound exchange their ions and form new compounds.

AB + CD → AD +CB

Other options are incorrect because,

Synthesis reaction:

It is the reaction in which two or more simple substance react to give one or more complex product.

AB → A + B

Single replacement:

It is the reaction in which one elements replace the other element in compound.

AB + C → AC + B

Decomposition reaction:

It is the reaction in which one reactant is break down into two or more product.

If 0.42 mole of helium occupies 9.9 L, how
many moles must be added to inflate the
balloon to 17.0 L?

Answers

Answer :

0.301 moles

Further explanation

Avogadro's hypothesis:  

In the same T,P and V, the gas contains the same number of molecules  

So the ratio of gas volume will be equal to the ratio of gas moles  

 

Given

n₁=initial mol of Helium : 0.42

V₁=initial volume : 9.9 L

V₂=final volume : 17 L

Required

number of moles added

Analysis

Use formula :

[tex]\tt \dfrac{V_1}{n_1}=\dfrac{V_2}{n_2}[/tex]

Solution

[tex]\tt n_2=\dfrac{n_1\times V_2}{V_1}\\\\n_2=\dfrac{0.42\times 17}{9.9}\\\\n_2=0.721~moles[/tex]

moles added :

0.721 - 0.42 =0.301 moles

Paraphrase

0.301 moles must be added to inflate the  balloon to 17.0 L

Tenemos un cuerpo de 40 g cuya densidad es 1,24 g/mL y otro objeto de 70 g con una densidad de 0,96 g/mL. Si introducimos cada uno en un recipiente con agua, ¿en qué caso subirá más el nivel de líquido?

Answers

Answer:

El nivel de líquido subirá más al introducirse el objeto de 70 g.

Explanation:

El nivel de líquido subirá más con el objeto que tenga mayor volumen.

Por lo tanto vamos a calcular el volumen de ambos objetos, usando la definición de densidad:

Densidad = Masa / Volumen

Si despejamos Volumen:

Volumen = Masa / Densidad

Ahora usamos esa ecuación y calculamos los volúmenes:

Objeto 1 ⇒ 40 g ÷ 1,24 g/mL = 32,26 mL  Objeto 2 ⇒ 70 g ÷ 0,96 g/mL = 72,92 mL

Por lo tanto el nivel de líquido subirá más con el segundo objeto.
