How is the number of electrons in an element determined?
elixir [45]

The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules. The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons.

Without doing any calculations, match the following thermodynamic properties with their appropriate numerical sign for the follo
siniylev [52]

Answer:

∆H > 0

∆Srxn <0

∆G >0

∆Suniverse <0

Explanation:

We are informed that the reaction is endothermic. An endothermic reaction is one in which energy is absorbed hence ∆H is positive at all temperatures.

Similarly, absorption of energy leads to a decrease in entropy of the reaction system. Hence the change in entropy of the reaction ∆Sreaction is negative at all temperatures.

The change in free energy for the reaction is positive at all temperatures since ∆S reaction is negative then from ∆G= ∆H - T∆S, we see that given the positive value of ∆H, ∆G must always return a positive value at all temperatures.

Since entropy of the surrounding= - ∆H/T, given that ∆H is positive, ∆S surrounding will be negative at all temperatures. This is so because an endothermic reaction causes the surrounding to cool down.

According to the kinetic molecular theory, temperature is directly proportional
rjkz [21]

Answer:

According to Kinetic Molecular theory, Temperature is directly proportional to the Average Kinetic energy of a molecules.

Explanation:

If the mass of the particles in a container is constant, then its moving molecules cause the gas gets warmer. On collision of molecules, Kinetic energy of molecules get high, so as a result, temperature gets high.

Fast moving of particles increases the temperature.

8. What type of reaction is this:
arsen [322]

Answer:

The reaction mentioned in the question is a decomposition reaction.

Explanation:

Decomposition reaction is a specific type of chemical reaction in which the reactant molecule undergo break down to generate its respective products.

 NaCl ⇒ Na + Cl2

In the above reaction sodium chloride(NaCl) undergo decomposition or break down to generate Sodium(Na) and chlorine gas(Cl2).
