Answer: (2)3.0 mol
Explanation: 222.3g= 222.3/74= 3.0 mol
1mol Ca(OH)2 is 74g
Answer:
B no observation pls mark me branilest
To answer the question above, we need to c<span>onvert 12.8 g to moles by dividing by 46.07 first.</span>
<span>For every mole you burn, you get 1235 kJ of heat. So multiply your number of moles by 1235. It'll be something in the neighborhood of 500. </span>
<span>Take your kJ that you calculated and divide by 5.65 to get the number of degrees that your calorimeter goes up. Add that to 25.
I hope my answer helped you</span>
The C¬C bond in H₃C¬CF₃ (423 kJ/mol) stronger than that in H₃C¬CH₃ (376 kJ/mol) because of the strong negative inductive effect of fluorine atom
<h3>What is Inductive effect?</h3>
When an electron- withdrawing or an electron- releasing species is allow to introduce to a chain of atoms (generally a carbon chain), according to the species corresponding negative or positive charge is start relayed through the carbon chain by the atoms through which it attached. This makes a permanent dipole to arise in the molecule and is referred to as the inductive effect.
<h3>Types of
Inductive effect</h3>
+ inductive effect
- inductive effect
<h3>What is negative inductive effect?</h3>
Whenever an electronegative atom, like halogen, is introduced to a chain of carbon atoms (generally carbon atoms), this results in unequal sharing of electrons which generates a positive charge which is transmitted through the chain.
This make a permanent dipole to arise in the molecule whereas the electronegative atom get a negative charge and the effect is known as the electron-withdrawing inductive effect, or the -I effect.
Thus, we concluded that the C¬C bond in H₃C¬CF₃ (423 kJ/mol) stronger than that in H₃C¬CH₃ (376 kJ/mol) because of the strong negative inductive effect of fluorine atom.

Answer:
The reaction is endothermic
Explanation:
we know that the reactants had to get energy from its surroundings which means that the reaction is endothermic
