Answer: Three groups bound to it with no lone pairs
i think...
Answer:
72.71 %
Explanation:
CO2. % C = 12.01/44.01 = 0.2729= 27.29% (we will divide 0.2729 with 100 to take the percentage). % O = 32.00/44.01 =0.7271 =72.71 %O in CO2.
CaCO₃ is a compound in and of itself thus it is not a polyatomic ion.
increase Polymer strain to failure is given below.
Explanation:
- Strain to failure gives the measure of how much the specimen is elongated to failure. By this it means that, it you have strain to failure of 3% measured in specimen of length 100 mm, the material will fail when it it elongated 3 mm, as experimented in tensile test. Therefore, for a material with higher strain to failure rate, the ductility is higher and tensile strength is lower.
- Tensile strength means the maximum mechanical stress (i.e. applied force divided by (initial) cross-section area of the specimen tested) during a tensile test, which is not directly correlated to the deformability or strain at failure or break since the tensile strength also is affected by the stiffness of the material. Therefore a ductile material might deform on a lower mechanical stress level than a stiffer one (this is the usual case), meaning its tensile strength is lower although its deformability is higher.
- Therefore, for a material with higher strain to failure rate, the ductility is higher and tensile strength is lower.
The entropy of the reaction can be calculated alike the enthalpy of the reaction which is equal to the difference between the summation of entropies of the products multiplied by their corresponding stoich coeff. and the summation of the entropies of the reactants multiplied by their corresponding stoich coeff. In this case, the answer is -146.8 J / mol K
