What is the formula for the ionic compound formed between sodium and oxygen?

Answer:

d. Urea nitrate

Explanation:

Urea nitrate is a fertilizer-based explosive that is produced in one step by reaction of urea with nitric acid. The is an exothermic reaction, therefore, necessary steps and precautions must be taken to ensure safety during the process. The equation of the reaction is given below:

(NH₂)₂CO (aq) + HNO₃ (aq) → (NH₂)₂COHNO₃ (s)

It is as easily-made explosive and can also be used as a catalyst in Diels-Alder reactions of aromatic amines.

In the presence of water, urea nitrate readily decomposes to its original components, urea and nitric acid.

On its own, urea  is commonly used as a deicer for sidewalks as it is a noncorrosive de-icing material. However, it is a more costly method of deicing,  compared to other methods and it is best used where water runs off into vegetation than into a water-body or a storm drain because of its high-oxygen demand which could result in its reducing the oxygen level of the water body. It It is readily found in nature (in our urine) and is also  synthesized artificially.  It has a very high nitrogen content, and is most often used as a nitrogen‐based fertilizer.

Answer:

1) Our Earth's iron liquid outer core rotating around the solid inner core

Explanation:

The earth's magnetic field or the geomagnetic field is produced as a result of the earth's iron liquid outer core rotating around the solid inner core.

This produces the earth's magnetic field.

The original concentration : 800%

Given

Diluted 1/40

Final concentration 20%

Required

The original concentration

Solution

Dilution is the process of adding solvent to get a more dilute solution.

The moles(n) before and after dilution are the same.

Can be formulated :

 n₁ = n₂

M₁.V₁ = M₂.V₂

diluted 1/40(dilution factor)⇒ V₁/V₂=1/40⇒V₂/V₁=40

M₂ = 0.2(20%)

Input the value for M₁ :

M₁=M₂ x (V₂/V₁)

M₁ = 0.2 x 40

M₂ = 8(800%)

The ball's potential energy is transferring into kinetic energy

Brainly if correct? Thanks!

Answer:

A

Explanation:

The balls potential energy is changing to kinetic energy

Answer:

25.2°C

Explanation:

Given parameters:

Energy applied to the water  = 1000J

Mass of water  = 50g

Final temperature  = 30°C

Unknown:

Initial temperature  = ?

Solution:

To solve this problem, we use the expression below:

            H  = m c Ф

H is the energy absorbed

m is the mass

c is the specific heat capacity

Ф is the change in temperature

     1000  = 50 x 4.184 x (30  -  initial temperature )

     1000  = 209.2(30 - initial temperature)

      4.78  = 30 - initial temperature

      4.78  - 30  = - initial temperature

         Initial temperature  = 25.2°C

Answer:

i. 3 moles.

ii. 132.03 grams.

iii. 105.6 grams.

Explanation:

Hello!

In this case, given the balanced chemical reaction, we can proceed as follows:

i. By starting with 5 moles of oxygen, via the 5:3 mole ratio we compute the produced moles of CO2:

[tex]n_{CO_2}=5molO_2*\frac{3molCO_2}{5molO_2} =3molCO_2[/tex]

ii. Now, since we have previously computed the moles of CO2 from the same moles of oxygen, by using its molar mass (44.02 g/mol), we obtain:

[tex]m_{CO_2}=3molCO_2*\frac{44.01gCO_2}{1molCO_2} =132.03gCO_2[/tex]

iii. Now, we need to combine the previously used two proportional factors for the calculation of the mass of CO2 from 128.00 grams of oxygen (molar mass 32.00 g/mol):

[tex]m_{CO_2}=128.00gO_2*\frac{1molO_2}{32.00gCO_2}*\frac{3molCO_2}{5molO_2}*\frac{44.01gCO_2}{1molCO_2}\\\\m_{CO_2}=105.6gCO_2[/tex]

Answer:

Its positive charge is attracted to the negative charge of Cl–.

Explanation:

The best description of why NH₄⁺ forms an ionic bond with Cl⁻ is that its positive charge is attracted to the negative charge of Cl⁻.

An ionic bond forms as a result of transfer of electrons. As a result the seemingly metal ion is attracted to the negative non-metal ion.

The electrostatic force of attraction between these ions is the ionic or electrovalent bond.

So, the attraction between these opposite charges will form the ionic bond.

Answer:

B: Its positive charge is attracted to the negative charge of Cl–

Introduction

As a diligent student of chemistry, you will likely encounter tons of reactions that occur in aqueous solution (perhaps you are already drowning in them!). When ions are involved in a reaction, the equation for the reaction can be written with various levels of detail. Depending on which part of the reaction you are interested in, you might write a molecular, complete ionic, or net ionic equation.

Definitions of molecular, complete ionic, and net ionic equations

A molecular equation is sometimes simply called a balanced equation. In a molecular equation, any ionic compounds or acids are represented as neutral compounds using their chemical formulas. The state of each substance is indicated in parentheses after the formula. [Huh?]

Let's consider the reaction that occurs between \text{AgNO}_3AgNO

Answer:

hydrogen, carbon, oxygen and nitrogen

Explanation:

Most organic compounds are made up of the four elements: hydrogen, carbon, oxygen and nitrogen.

Most organic compounds are made of just four elements are  hydrogen, carbon, oxygen and nitrogen.

The term organic compound is defined as a substance that contains covalently - bonded carbon and hydrogen and often with other elements.

Benzoic acid, aromatic compounds, benzoic aldehyde, propanoic acid, butanoic acid, malonic acid, amines, heterocyclic compounds, VOC, benzoic acid, and diethyl malonate are some examples of organic compounds.

Carbohydrates, lipids, proteins, and nucleotides are all organic compounds that are required for human function. Because they contain both carbon and hydrogen, these compounds are classified as organic.

Thus, Most organic compounds are made of just four elements are  hydrogen, carbon, oxygen and nitrogen.

Answer:

[tex]\Delta T=-146.5K[/tex]

Explanation:

Hello!

In this case, given the Charles' law which allows us to understand the volume-temperature behavior as shown below:

[tex]\frac{T_1}{V_1}=\frac{T_2}{V_2}[/tex]

Thus, given that we need to calculate the final temperature after the compression, we obtain:

[tex]T_2=\frac{V_2T_1}{V_1}=\frac{1.00L*293K}{2.00L}\\\\T_2=146.5K[/tex]

Thus, the temperature change would be:

We can see that the ions in the reactants exchanged their partners in the products. Solid lead II sulphate was precipitated.

Reaction 2 is a single replacement reaction. Solid manganese hydroxide is formed.

Mass (in g) of the excess reactant (P₄) left = 7.626 g

Given

Reaction

P4(s)+6Cl2(g)→4PCl3(l)

45.57 g P4 and 130.2 g Cl2

Required

mass (in g) of the excess reactant left

Solution

mol P₄ (MW=124 g/mol) :

45.57 : 124 = 0.3675

mol Cl₂(MW=71 g/mol) :

130.2 : 71 = 1.834

mol : coefficient of reactant : P₄ : Cl₂ :

= 0.3675/1 : 1.834/6

= 0.3675 : 0.306

Cl₂ as limiting reactant(smaller ratio)

Reacted mol of P₄ (as an excess reactant):

=1/6 x 1.834

= 0.306

Unreacted mol of P₄ :

= 0.3675 - 0.306

= 0.0615

Mass of P₄(left) :

= 0.0615 x 124

= 7.626 g
