Afina-wow [57]
The chance of their baby being blue is a 25% chance. There is a 50% chance that their baby will carry the trait but not have the feature. Since SpongeBob is heterozygus he carries the blue trait so his kid has a 50% chance of being blue from his genes. SpongeSusie is blue so she has a 100% of her child being blue.

lesantik [10]
The appropriate response is water. This reversible reaction can be broken into two responses. These two responses are happening all the while, which implies that the reactants are responding to yield the items, as the items are responding to deliver the reactants. Crashes of the responding atoms cause substance responses in a shut framework.

If a non-cyclic alkane shows a molecular ion peak at m/z 3.80 × 102, what is the chemical formula?
soldier1979 [14.2K]
The General Equation of Alkane is as follow,

                                              CnH₂n₊₂          ------- (1)
As m/z = 380
So,
                                              CnH₂n₊₂  =  380
Or,
                                              12n+ 1₂n₊₂  =  380

                                              12n+ ₂n ₊ ₂  =  380

                                              14n ₊ ₂  =  380

                                                   14n  =  380 - 2

                                                   14n  =  378

                                                       n  =  378 / 14

                                                       n  =  27
Now, putting value of n in eq. 1

                                              C₂₇H₍₂₇ₓ₂₎₊₂

                                                  C₂₇H₅₆
Result:
           n  =  C  =  27

           y  =  H  =  56

A Questic
Ivanshal [37]

Answer:

No, it is not feasible because the Gibbs free energy change is positive

Explanation:

∆Hreaction= (-602 KJ/mol) - (-348 KJ/mol) = -254 KJ/mol

∆Sreaction = (42 + 27) J/Kmol - (33 + 44) J/K = -8J/Kmol

From;

∆G = ∆H - T∆S

∆G = 254 × 10^3 J/mol - [340K × (-8 J/Kmol)]

∆G = 2.57 × 10^5 J/mol

Note that when the change in free energy is positive, a reaction is non spontaneous. Only a reaction that has a negative change in free energy is spontaneous.
