What is the name of this ether organic compound?

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.

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:

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

The solution of manganese ion, Mn2+ is colorless. This way, the reaction involves a colour change from pink to transparent.

There is no option with this information.

So, the best answer is (A)

Answer:

C)pink colour of the Mn+2.

Explanation:

First of all, a titration involving the change from MnO4- to Mn2+ is a redox reaction.

This redox reaction does not need an indicator because the MnO4- has a deep violet colour while Mn2+ has a light pink colour.

Hence, the change from MnO4- to Mn2+ is signaled by the appearance of the light pink colour of Mn2+ at end point.

Answer:

migratory distribution

Explanation: The pattern of migratory distribution of species may require collaboration between different countries for effective preservation. This is because species migration can make them enter different territories, which will need to provide an effective level of preservation for species survival

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:

[tex]\Delta T=T_2-T_1=146.5K-293K\\\\\Delta T=-146.5K[/tex]

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

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

A double replacement reaction is one in which ions exchange partners.

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.

Reactions 3 and 4 are redox processes as shown in the respective equations.

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–

The given reaction is double displacement reaction. In this reaction arsenic trichloride and hydrogen sulfide react and produced arsenic sulfide and hydrogen chloride. In double displacement reaction both anion an cation of reactants are exchanged with each other.

Double replacement:

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

Answer:

CH2

Explanation:

there is a common factor for 9;18 which is 9 so u divide both numbers by it 9/9 and 18/9 giving 1:2 so 1 C to every 2 H so CH2

The empirical formula of C9H18 will be CH2.

The empirical formula of a compound shows the ratio of atoms present in a compound. The molecular formula of the compound shows the total number of atoms present in a compound.

Here, C9H18 if we divide the number of total atoms by 9, C9/ 9, and H18/ 9. the ratio will be in the form of 1: 2. therefore, the empirical formula will be CH2.

C9H18 is the molecular formula of the compound, while CH2 is the empirical formula of the compound. The molecular formula of butane is C4H16, then its empirical formula is CH4.  The molecular formula of compound is P4H10 then its empirical formula is P2H5.

Therefore, The empirical formula of C9H18 will be CH2.
