Answer:

Condensed equation: $3K_2CrO_4(aq)+2Fe(NO_3)_3(aq)\rightarrow Fe_2(CrO_4)_3(s)+6KNO_3(aq)$

Complete ionic equation : $6K^+(aq)+3CrO_4^-(aq)+2Fe^{2+}(aq)+6NO_3^-(aq)\rightarrow Fe_2(CrO_4)_3(s)+6K^+(aq)+6NO_3^-(aq)$

Net ionic equation : $3CrO_4^-(aq)+2Fe^{2+}(aq)\rightarrow Fe_2(CrO_4)_3(s)$

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

The balanced chemical equation is:

$3K_2CrO_4(aq)+2Fe(NO_3)_3(aq)\rightarrow Fe_2(CrO_4)_3(s)+6KNO_3(aq)$

Condensed equation : $3K_2CrO_4(aq)+2Fe(NO_3)_3(aq)\rightarrow Fe_2(CrO_4)_3(s)+6KNO_3(aq)$

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.

$6K^+(aq)+3CrO_4^-(aq)+2Fe^{2+}(aq)+6NO_3^-(aq)\rightarrow Fe_2(CrO_4)_3(s)+6K^+(aq)+6NO_3^-(aq)$

Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations. Spectator ions are the ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

$3CrO_4^-(aq)+2Fe^{2+}(aq)\rightarrow Fe_2(CrO_4)_3(s)$

you and your friends are at the park on a sunny day, and you are playing on the slide. As you sold down, the hot slide burns you

zzz [600]

Metal is a great conductor of heat while rope does not collect heat from the radiation from the sun as much or contain it while if metal is out in the sun all day it just keeps getting hotter and hotter and when you touch the rope it does not have much heat to transfer but the metal slide is hot enough to irritate your skin

Explain how heat would change the density of a parcel of air

BartSMP [9]

<span>Heat would make the molecules move faster so they would spread out therefore making air less dense.
Less dense means less packed. Heat increase the kinetic energy</span>

A gas stream containing n-hexane in nitrogen with a relative saturation of 0.58 (as a fraction, multiply by 100% if you prefer %

kondor19780726 [428]

This problem is describing a gas mixture whose mole fraction of hexane in nitrogen is 0.58 and which is being fed to a condenser at 75 °C and 3.0 atm, obtaining a product at 3.0 atm and 20 °C, so that the removed heat from the system is required.

In this case, it is recommended to write the enthalpy for each substance as follows:

$H_{C-6}=y_{C-6}C_v(T_b-Ti)+\Delta _vH+C_v(T_f-Tb)\\\\H_{N_2}=y_{N_2}C_v(T_f-Ti)$

Whereas the specific heat of liquid and gaseous n-hexane are about 200 J/(mol*K) and 160 J/(mol*K) respectively, its condensation enthalpy is 31.5 kJ/mol, boiling point is 69 °C and the specific heat of gaseous nitrogen is about 29.1 J/(mol*K) according to the NIST data tables and $y_{C-6}$ and $y_{N_2}$ are the mole fractions in the gaseous mixture. Next, we proceed to the calculation of both heat terms as shown below:

$H_{C-6}=0.58*200(69-75)+(-31500)+160(20-69)=-40036J/mol\\\\H_{N_2}=0.42*29.1(20-75)=-672.21J/mol$

It is seen that the heat released by the nitrogen is neglectable in comparison to n-hexanes, however, a rigorous calculation is being presented. Then, we add the previously calculated enthalpies to compute the amount of heat that is removed by the condenser:

$Q=-40036+(-672.21)=-40708.21J$

Finally we convert this result to kJ:

$Q=-40708.21J*\frac{1kJ}{1000J}\\\\Q=-40.7kJ$

Al(s) + NiSO4(aq)<br> Balance

irinina [24]

Answer:

$2Al(s) + 3NiSO4 --> Al2(SO4)3 + 3Ni$

Explanation:

This reaction type is a single replacement. The format of a single replacement is:

$A+BC --> B+AC$

A= Al

B= Ni

C= SO

The coefficient 3 for Ni would become a subscript for AC. After you plug those into the reaction you need to count how many of each are on the left side and try to get the same number on the right side. Both sides must be equal to have a balanced equation.
