Answer:

Sr(NO3)2 + Na2CO3 --------> SrCO3 + 2NaNO3

Total ionic equation;

Sr^2+ + NO3^- + Na^+ + CO3^2- -----> SrCO3 + 2NaNO3

Net ionic equation;

Sr^2+ + CO3^2- -----> SrCO3

Explanation:

The molecular equation shows the reactions of the compounds to give the products. It shows the molecular formula of reactants and products.

The total ionic equation shows the ions that recombine to form the products of the reaction.

The net ionic shows the major ionic reaction that took place in the system.

Hence, the net ionic equation explicitly shows the major species that are involved in a reaction, while a complete ionic equation includes the spectator ions.

How is a unit cell like a formula unit?
frutty [35]

Answer:

Understanding the unit cell of a crystalline solid will help you in determining the empirical formula of the ionic solid compound because they both represent the smallest portion of the whole crystalline solid proportion.

Explanation:

A unit cell is the smallest portion of a crystal lattice, that can show the 3 dimensional pattern of the whole crystal.A formula unit is the lowest whole number ratio of ions in a an ionic compound.By considering the smallest repeating units/ unit cell, you can describe the structure of a crystalline solid.Knowing this can help in determining the empirical formula of the ionic solid compound.

Complete Question

Questions Diagram is attached below

Answer:

*  W=1142.86Joule

*  Q=997.7J

*  H=2140.5J

Explanation:

From the question we are told that:

Temperature T=337K

Pressure P=(60-55)Pa*10^5

VolumeV=(1.6-1.4)m^3*10^{-3}

Generally the equation for gas Constant is mathematically given by

\frac{P_2}{P_1}=\frac{V_1}{V_2}^n

 \frac{55*10^5}{60*10^5}=\frac{1.4*10^{-3}}{1.6*10^{-3}}^n

 n=0.65

Therefore

Work-done

 W=\int{pdv}

 W=\frac{55*10^5*1.6*10^{-3}*60*10^5*1.4*10^{-3}}{1-0.65}

 W=1142.86Joule

Generally the equation for internal energy is mathematically given by

 Q=mC_vdT\\\\Q=\frac{3*1*3.314*16}{1.4-1}

 Q=997.7J

Therefore

 H=Q+W

 H=997.7J-11.42.9

 H=2140.5J
