Answer: For a gas to become a liquid, large numbers of particles must clump together. Particles will clump together when the attraction between them overcomes their motion. For this to happen, energy must be removed from the gas to slow the particles down. So, condensation is an exothermic change.

Answer:

It has 2 phosphorus atoms in 1 mol

so for 1.75 mol =2×1.75

Explanation:

need thanks and make me brainiest if it helps you

There will be two atoms of phosphorus in the 1.75 mol of calcium phosphate.

Atoms are the smallest unit of matter. In a chemical reaction, the number of atoms shows the quantity of an element in the compound or reaction. Phosphorus is a chemical element that is preset in the periodic table.

In calcium phosphate, Ca3(PO4)2, the number of atoms can be calculated by counting the number of moles that is given in the equation.

The number of atoms of calcium is 3, and the number of phosphorus atoms is 2.

Now given the 1.75 mol of calcium phosphate, so the number of atoms of phosphorus will be the same in any number of moles of calcium phosphate. So there will be 2 atoms of phosphorus in the given equation.

Thus, the number of atoms is two.

Answer:

Nonmetals are further to the right on the periodic table, and have high ionization energies and high electron affinities, so they gain electrons relatively easily, and lose them with difficulty.

Explanation:

They also have a larger number of valence electrons, and are already close to having a complete octet of eight electrons.

Periodic table is divided as metals, non metals, noble gases and semiconductors. Among these nonmetals tend to have high electron affinities because of small size and high effective nuclear charge.

Non metals are the element that have property to gain electron. When any element gain electron then element attain negative charge and that element is called anion.

As we go from left to right in periodic table, the size of element decreases as number of electrons keep on adding electrons in the same shell . As the number of electrons increases, the number of proton in the nucleus also increases. Due to this, the hold of nucleus on the outermost proton increases and the size decreases. Due to this, the ionization energy increases and hence the power to gain electron increases.

Therefore, nonmetals tend to have high electron affinities because of small size and high effective nuclear charge.

The answer will be NaCl and H2O

(b) An equation to show the reaction between hydrogen ions and hydrogen ions and hydroxide ions is given below :

H+   +   OH−   ⇄ H2O

This reaction is known as neutralization reaction.

(c) Joey could tell us the reaction is over only when we obtained salt and water from the given chemical reaction (NaOH + HCl). This a basically a neutralization reaction ( the reaction  generally finished at equilibrium)

(d) pH is 7.

This is because at the ending point the moles of HCl = the moles of NaOH so all that is present is H2O, Cl–, and Na+. So, the pH is 7.

Answer:

1.5 mol

Explanation:

Given data:

Number of moles of H₂ = 4.5 mol

Number of moles of N₂ = ?

Solution:

Chemical equation:

N₂ + 3H₂     →        2NH₃

Now we will compare the moles of hydrogen and nitrogen.

                  H₂         :        N₂

                    3         :          1

                  4.5        :          1/3×4.5 = 1.5 mol

Thus, 1.5 moles of nitrogen are required to react with hydrogen.  

Answer:

7 moles of NaOH will produced.

Explanation:

Given data:

Number of moles of sodium oxide = 3.5 mol

Number of moles of sodium hydroxide produced = ?

Solution:

Chemical equation:

Now we will compare the moles of sodium oxide with sodium hydroxide.

                 Na₂O            :         NaOH      

                    1                 :             2

                  3.5               :         2/1×3.5 = 7

Cu⇒ 1 atom

N⇒2 atoms

O⇒6 atoms

Total 9 atoms

The empirical formula is the smallest comparison of atoms of compound forming elements.  

A molecular formula is a formula that shows the number of atomic elements that make up a compound.  

(empirical formula) n = molecular formula  

Chemical formula : Cu(NO₃)₂

Number of Cu : 1

Number of N : 2

Number of O = 2 x 3 = 6

Total atoms in Cu(NO₃)₂ : 1 + 2 + 6 = 9

The pressure of the gas : 1.1685 atm

In general, the gas equation can be written

V = volume, liter  

n = number of moles  

R = gas constant = 0.08206 L.atm / mol K  

T = temperature, Kelvin  

n=moles=1.5

V=volumes = 30 L

T=temperature=285 K

Answer:

It is not an oxidation-reduction reaction. The formation of carbon dioxide and water are redox reactions which involve the oxidation of carbon and hydrogen respectively with oxygen being reduced in both the case.

Explanation:

This is not a redox reaction.

A redox reaction is the one that involves reduction and oxidation simultaneously. In a redox reaction, one of the substance gets oxidised and behaves as a reducing agent and the other gets reduced that behaves as an oxidizing agent.

The oxidation or reduction of the substance is decided by the change in oxidation number of the atom which is the charge that an atom appears to have on forming ionic bonds with other heteroatoms.

In this reaction, no change in oxidation state of the atoms takes place and thus this reaction is not a redox reaction.
