what reaction type is the followong reaction ​

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:

Na₂O + H₂O      →     2NaOH

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

                 Na₂O            :         NaOH      

                    1                 :             2

                  3.5               :         2/1×3.5 = 7

7 moles of NaOH will produced.

The equilibrium constant(Kc) is equal to the concentration of the products over the concentration of the reactants, and each coefficient of the compound in an equilibrium state

The equilibrium constant or Kc is the value of the concentration product in the equilibrium state of the substance in the right segment divided by the product of the substance in the left section, each of which has a reaction coefficient raised

solid (s) and liquid (l) have no concentration, so these two phases are not involved in the equilibrium constant KC (given the value = 1).

The equilibrium constant based on concentration (Kc) in a reaction

pA + qB -----> mC + nD

[tex]\tt Kc=\dfrac{[C]^m[D]^n}{[A]^p[B]^q}[/tex]

1.   N2(g) + O2(g) ⇌ 2NO(g)

[tex]\tt Kc=\dfrac{[NO]^2}{[N_2][O_2]}[/tex]

2. N2(g) + 3H2(g) ⇌ 2NH3(g)

[tex]\tt Kc=\dfrac{[NH_3]^2}{[N_2][H_2]^3}[/tex]

3. 2SO2(g) + O2(g) ⇌ 3SO3(g)

[tex]\tt Kc=\dfrac{[SO_3]^3}{[SO_2]^2[O_2]}[/tex]

4. 2Fe(S) + 4H2O(g) ⇌Fe3O4(s) +4H2(g)​

Answer:

True

Explanation:

Two liquids of a mixture having the same boiling point cannot be separated using the process of distillation.

Distillation is one of the process of physical separation techniques.

So without a difference in the boiling point of the compound that makes up a mixture, the separation by distillation will not be possible.

Answer:

Explanation:

1. It reacts with hydrogen when heated

     Chemical property

2. It is a yellow solid at room temperature

    Physical property

3. It is soluble in carbon disulfide

    Chemical property

4. Its density is 2.97 g/cm3

    Physical property

5. It melts at 113°C

    Physical property

Physical properties tells us everything about what substance is when no change is occurring to its constituents.

It can be observed using apparatus and instruments. Examples are state of matter, color, odor, taste, texture, hardness, solubility in water, density, melting point and boiling point

Chemical properties are those properties that tell us about what a substance can do as regards to whether or not the substance reacts with other substances. Examples are flammability, rusting of irons, precipitation, decomposition of water by an electric current.

Answer:

Ring is made up off copper.

Explanation:

Given data:

Mass of ring = 89.2 g

Volume of water = 10 mL

Volume of water + ring = 20 mL

Ring is made up of = ?

Solution:

Volume of ring = (Volume of water + ring) - Volume of water

Volume of ring = 20 mL - 10 mL

Volume of ring = 10 mL

Density:

Density = mass/volume     ( 1 mL = 1 cm³)

d = 89.2 g/  10cm³

d = 8.92 g/cm³

Thus, ring is made up off copper.

The activity series of metals reflect the stability of metals are "the metals highest on the list are the least stable."

The organization of metals in a declining sequence of respective reactivities is referred to as the "activity series," also described as the "reactivity series" of metals.

Materials having the qualities of being bright, hard, fusible, malleable, ductile, etc. were known as metals.

Answer:

Deposition

Explanation:

The process of deposition is when an object goes from a gas to a solid. In the picture, the first container had a gas (molecules were far apart). In the second, the molecules were tightly packed (a solid).

Hope this helps!

Answer:

Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds.

The  original pressure of the gas : 2.507 atm

Boyle's law and Gay Lussac's law  

[tex]\tt \dfrac{P_1.V_1}{T_1}=\dfrac{P_2.V_2}{T_2}[/tex]

P1 = initial gas pressure (N/m² or Pa)  

V1 = initial gas volume (m³)  

P2 = final gas pressure  

V2 = final gas volume

T1 = initial gas temperature (K)  

T2 = final gas temperature  

V₁=28 L

T₁=45+273=318 K

P₂=2 atm

V₂=34 L

T₂=35+273=308 K

then initial pressure :

[tex]\tt P_1=\dfrac{P_2.V_2.T_1}{V_1.T_2}\\\\P_1=\dfrac{2\times 34\times 318}{28\times 308}\\\\P_1=2.507~atm[/tex]
