bezimeni [28]3 years ago
3 0

Answer: The correct order of coefficients is 4, 5, 4 and 6.

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side.

The balanced chemical equation is:

4NH_3+5O_2\rightarrow 4NO+6H_2O

The correct order of coefficients is 4, 5, 4 and 6.

Titanium metal is used as a structural material in many high-tech applications such as in jet engines.
Elza [17]

Answer:

a.Cp=0.523

b.Cp=25.02\frac{J}{mol^\circ C}

Explanation:

a. First, we solve the specific heat equation as follows:

Q=mCp\Delta T\\Cp=\frac{Q}{m\Delta T}\\Cp=\frac{89.7J}{33.0g\times5.20^\circ C}=0.523

b. Then, we use the molar mass of titanium to determine its molar heat capacity, as follows:

Cp=0.523\frac{J}{g^\circ C}\times 47.87\frac{g}{mol}\\Cp=25.02\frac{J}{mol^\circ C}
