Consider the following reaction, which is spontaneous at room temperature. C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g) Is ΔS positive o
Ugo [173]

Answer:

∆H = negative and ∆S = positive.

Explanation:

The reaction given in the question is spontaneous at room temperature ,

hence ,

The the gibbs free energy , i.e. ,∆G will be negative for  spontaneous reaction

According to the formula ,

∆G = ∆H -T∆S

The value of ∆G can be negative , if  ∆H has a negative value and  ∆S has a positive value , because , T∆S  , has a negative sign .

Hence , the answer will be , ∆H = negative and ∆S = positive.

Why does the chemical reaction seen here obey the law of conservation of matter?
ss7ja [257]

Why does the chemical reaction seen here obey the law of conservation of matter?

<u><em>Answer:</em></u>

  • Because there are the same number of atoms of each element shown on both sides

<u><em>Explanation</em></u>

  • As in chemical reactions, atoms bonds are break and new bonds are formed. As new substance are formed but overall they have same elements, no new elements come from outside or go to outside. In other words , rearrangement of atoms take place but number of atoms remained same.

                            NaOH + HCl -----> NaCl + H2O

  • As in above reaction there are the same number of atoms of each element shown on both sides .
