Answer:

"A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat. Combustion reactions must involve O2 as one reactant. The combustion of hydrogen gas produces water vapor." and "A synthesis reaction occurs when two or more reactants combine to form a single product. ... In a double replacement reaction, two compounds exchange elements. A combustion reaction occurs when a substance reacts quickly with oxygen. Combustion is commonly called burning"

Answer:

32 grams

Explanation:

Ignore the other answer. Two oxygen atoms have a mass of 32 grams. You can also arrive at this answer by subtracting the given values (i.e. 36 - 4 = 32).

The correct Lewis dot structure for [tex]BeH_2[/tex] is Be : H : H

The Lewis dot structure shows the valence electrons as dots. The valence electrons of beryllium are shown as 2 dots on the left side of the atom.

The central atom, beryllium, has 2 valence electrons where each hydrogen atom has 1 valence electron. To form a stable molecule, beryllium shares its 2 valence electrons with the 2 hydrogen atoms, each of which shares its 1 valence electron with beryllium which gives each atom a full outer shell of electrons.

CO₂ will not conduct electricity

Answer:

Explanation:

While trying to write the chemical formula for a compound (a neutral molecule), one must identify and exchange the charge of the cation with that of the anion to become the subscript of one other. For example

Aluminium oxide has Aluminium (Al) and oxygen (O); since Al has a charge of 3+ (the cation) and O has a charge of 2- (the anion), the compound would have it's charges as Al³⁺O²⁻ and when the charges are exchanged to there subscripts, it would form Al₂O₃; thus there would be two cations of aluminium for every three anions of oxygen in order to have a neutral molecule.

This same explanation can be given to Aluminium sulfite. Aluminium sulfite has Aluminium (Al) and sulfite (SO₃). Al has a charge of 3+ (cation) while sulfite has a charge of 2- (anion), with the compound having it's charges as Al³⁺(SO₃)²⁻ and when the charges are exchanged to there subscripts, it would form Al₂(SO₃)₃ and would thus have 2 cations of aluminium (Al³⁺) for every 3 anions of sulfite (SO₃³⁻) in order to have a neutral molecule.

Answer:

Chemists keep track of how electrons are transferred between atoms in a reaction using an oxidation number. If the oxidation number of an element in the reaction increases or becomes less negative, the element has been oxidized, while a decreased or more negative oxidation number means the element has been reduced.

Answer:

It has 5 neutrons

Explanation:

The fact that it is a neutral atom tells us that the number of electrons and protons is the same:

The average mass of an atom is the sum of the number of protons and the number of neutrons:

With the above information in mind we can calculate the number of neutrons:

Explanation:

Distillation is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components in the mixture. In either case, the process exploits differences in the relative volatility of the mixture's components. In industrial applications, distillation is a unit operation of practically universal importance, but it is a physical separation process, not a chemical reaction.

To Find :

The mass, in grams, of [tex]1.505 \times 10^{23}[/tex] molecules of carbon disulfide (CS₂).

Solution :

Molecular mass of CS₂ = 76 gm/mol .

It means that mass of [tex]6.022 \times 10^{23}[/tex] molecules of CS₂ is 76 gm/mol.

Let, mass of [tex]1.505 \times 10^{23}[/tex] molecules of carbon disulfide (CS₂) is x.

So,

[tex]x= 76\times \dfrac{1.505 \times 10^{23}}{6.022\times 10^{23}}\\\\x = 76 \times \dfrac{1.505}{6.022}\\\\x = 19 \ gm[/tex]

Therefore, the mass in gram is 19 gm.

Balanced equation : C. CH₄ + 4Cl₂⇒  CCl₄+ 4HCl

Equalization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:  

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.  

2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product  

3. Select the coefficient of the substance with the most complex chemical formula equal to 1  

Reaction

CH₄ + Cl₂⇒  CCl₄+ HCl

aCH₄ + bCl₂⇒  CCl₄+ cHCl

C, left=a, right=1⇒a=1

H, left=4a, right=c⇒4a=c⇒4.1=c⇒c=4

Cl, left=2b, right=4+c⇒2b=4+c⇒2b=4+4⇒2b=8⇒b=4

The equation becomes :

CH₄ + 4Cl₂⇒  CCl₄+ 4HCl

Answer:

0 kgm/s

Explanation:

The momentum of Bob while resting at the river is 0 kgm/s.

This is because the momentum of any object at rest is 0.

 Momentum is the quantity of motion a body contains. It is mathematically expressed as;

  Momentum  = m x v

m is the mass

v is the velocity

 So at rest, the velocity of a body is 0m/s and therefore, the momentum is O

Answer:

B.The Chocolate Chip Model

Explanation:

Answer: Bismuth (Bi) , Nitrogen family

Explanation:

As the element has 5 valence electrons in the sixth energy level, which mens it belongs to 6th period as the valence electron has entered the 6th energy level.

Now as the electrons are  filled according to afbau's rule , the electronic configuration of the element will be :

[tex][Xe]4f^{14}5d^{10}6s^26p^3[/tex]

Now as the atomic number of element is equal to the number of electrons in a neutral atom , the atomic number is 83 and the element is Bismuth (Bi). As the last electron enters p -subshell , it is  a p block element. It lies in group 15 which is nitrogen family.
