The transfer of heat between substances by thermal conduction is only possible when they are in direct contact with each other.

The transfer of heat from the hotter end to the colder end of object is known as conduction.

The spontaneous flow of Heat from a hotter to a colder body ie, heat is conducted from the hotplate of an electric stove to the saucepan when it is in contact with it.

The better the conductor, the more rapidly heat will be transferred.

Thus, The transfer of heat between substances by thermal conduction is only possible when they are in direct contact with each other.

Lakes dry up. Shortage of water. Decrease in humidity.

Answer:

I have the lowest electronegativity of the nonreactive elements. My family name is alkali metals. I am classified as a reactive metal. I have one valence electrons.

Explanation:

Electronegativity refers to the ability of the atoms of an element to attract electrons to itself. Based on their nature, non-metals are electronegative elements whereas metal are electropositive as they have a tendency to give up their electrons rather than attract electrons to themselves.

In the periodic table of elements, non-metallic character, and hence, electronegativity increases from left to right across a period, and decreases down a group. The most electropositive element is fluorine. On the other hand, electropositivity decreases across a period from left to right but increases on going down a group. Hence, the most electropositive element is Francium. This also means that Francium is the least electronegative element,

francium belong to the group 1A of the periodic table which are the most reactive metals. The family of group 1A elements are known as alkali metals. They possess only one valence electron which they easily give up to form univalent positive ions or cations. Francium is a radioactive element.

Answer:

24.7 C

Explanation:

I don't know how

The final temperature of 1000 ml water by the addition of 5 g ammonium perchlorate has been 24.7 degree Celsius.

With the addition of 5 g of ammonium perchlorate, the drop in temperature has been:

The addition of 5 g sample to 100 ml water has absorption of energy, that results in change in temperature of 3 degree Celsius.

The heat absorbed by sample has been given as:

Heat = mass × specific heat × change in temperature

Since, the same mass of sample has been added to 25 degree Celsius water, according to law of conservation, the change in density for both the changes has been equivalent.

The ratio of masses has been equivalent to the ratio of volume.

[tex]\rm \dfrac{Mass\;at\;1000\;ml}{Mass\;at\;100\;ml}\;=\;\dfrac{Volume\;at\;1000\;ml}{Volume\;at\;100\;ml}\\\\\\\dfrac{Mass\;at\;1000\;ml}{Mass\;at\;100\;ml}\;=\;\dfrac{1000\,ml}{100\;ml}\\\\\\\dfrac{Mass\;at\;1000\;ml}{Mass\;at\;100\;ml}\;=\;10[/tex]

Since, the mass at 100 ml and mass at 1000 ml has been equal, the heat absorbed by the sample has also been equal. Equating the values:

Mass at 100 ml × Specific heat × Change in temperature = Mass at 1000 ml × Specific heat × Change in temperature

[tex]\rm 3\;degree\;Celsius\;= \;\dfrac{Mass\;at\;1000\;ml}{Mass\;at\;100\;ml}\;\times\;Change\;in\;temperature\\\\3\;degree\;Celsius\;= \;10\;\times\;Change\;in\;temperature\\\\Change\;in\;temperature\;=\;\dfrac{3}{10}[/tex]

Change in temperature =  0.3 degree Celsius.

The initial temperature of water has been 25 degree Celsius. The change in temperature has been given by:

Change in temperature = Initial temperature - Final temperature

0.3 degree Celsius = 25 degree Celsius - Final temperature

Final temperature = 25 - 03 degree Celsius

Final temperature = 24.7 degree Celsius.

The final temperature of 1000 ml water by the addition of 5 g ammonium perchlorate has been 24.7 degree Celsius.

Answer:

D is the answer

Like my answer

There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Therefore, the correct option is option D.

Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.

An ionic compound is a metal and nonmetal combined compound.  Ionic compound are very hard. They have high melting and boiling point because of strong ion bond.

The two elements will form an ionic bind because one of the elements will donate two electrons to the other elements in order to have full outer shells.

Therefore, the correct option is option D.

Answer:

Is used to predict the spectra of hydrogen and hydrogen like species

Explanation:

The Bohr's model of the atom was propounded by Neis Bohr. In his theory, an atom is composed of quantized energy levels in which electrons may be found.

The transition of an electron between energy levels leads to the absorption or emission of energy in the form of a photon of visible light. The energy absorbed or emitted depends on the energy difference between the two energy levels.

The model is successful at predicting the electronic spectra of one electron species but totally fails when the specie has more than one electron. Also, the model fails to show the true shape of the electron orbitals within an atom.

Answer: The number of protons in cation is more than the number of electrons

Explanation:

cations are positive ions that means that they lose electrons to be stable nd have electron configuration (atomic number ) equivalent to the preceding noble gas

as : sodium 11 , it loses on electron to be stable and its electron configuration is equivalent to neon 10

so ,the number of protons in cation is more than the number of electrons

Answer: D. 1600 L

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

To calculate the moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given volume}}{\text {Molar volume}}[/tex]

[tex]\text{Number of moles of nitrogen}==\frac{1000L}{22.4L}=44.6moles[/tex]

[tex]\text{Number of moles of hydrogen}==\frac{2400L}{22.4L}=107.1moles[/tex]

[tex]N_2(g)+3H_2(g)\rightarrow 2NH_3(g)[/tex]  

According to stoichiometry :

3 moles of [tex]H_2[/tex] require 1 mole of [tex]N_2[/tex]

Thus 107.1 moles of [tex]H_2[/tex] will require=[tex]\frac{1}{3}\times 107.1=35.7moles[/tex] of [tex]N_2[/tex]

Thus [tex]H_2[/tex] is the limiting reagent as it limits the formation of product and [tex]N_2[/tex] is the excess reagent.

As 3 moles of [tex]H_2[/tex] give = 2 moles of [tex]NH_3[/tex]

Thus 107.1 moles of [tex]H_2[/tex] give =[tex]\frac{2}{3}\times 107.1=71.4moles[/tex]  of [tex]NH_3[/tex]

Volume of [tex]NH_3=moles\times {\text {Molar volume}}=71.4moles\times 22.4L/mol=1600L[/tex]

Thus volume of ammonia produced is 1600 L
