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.

If there are

. Typically, in a question like this, you would also be asked to calculate the volume the gas occupies under standard conditions, and the
p

of the resultant solution (would it be high, low, neutral?).
The answer is K3PO4(s) → 3K+(aq) + PO43–(aq) since water-soluble ionic tripotassium phosphate dissociates completely into K+ and PO43– ions when dissolved, that is, no K3PO4 remains in the solution. Carbonic acid H2CO3 and acetic acid CH3COOH are weak electrolytes since they are weak acids that do not completely ionize, while nonelectrolyte CH3OH do not dissociate into ions.
use the equation q=mcΔt. convert 13 mg to g. so it becomes .013g which will be the mass. C is specific heat of water which is always 4.184. Delta t is 75-1 which is 74. (.013)(4.184)(74) = 4.025
