Answer is: because carbon(IV) oxide is released.
For example if baking soda is used for <span>the pizza dough, than on heat carbon(IV) oxide is product of chemical reaction:
2NaHCO</span>₃ → Na₂CO₃ + CO₂ + H₂O.
If we use yeast (<span>single-celled microorganism)</span>, also carbon(IV) oxide produced, because yeast turns sugars into carbon(IV) oxide.
Answer:
The molality of the glycerol solution is 2.960×10^-2 mol/kg
Explanation:
Number of moles of glycerol = Molarity × volume of solution = 2.950×10^-2 M × 1 L = 2.950×10^-2 moles
Mass of water = density × volume = 0.9982 g/mL × 998.7 mL = 996.90 g = 996.90/1000 = 0.9969 kg
Molality = number of moles of glycerol/mass of water in kg = 2.950×10^-2/0.9969 = 2.960×10^-2 mol/kg
Answer: option D - The total number of nucleons changes.
Explanation:
Nuclear Reaction is best described as a process such as the fission of an atomic nucleus, or the fusion of one or more atomic nuclei and / or subatomic particles in which the NUMBER of PROTONS and / or NEUTRONS in a nucleus CHANGES; the reaction products may contain a different element or a different isotope of the same element.
Note that the NUCLEONS refers to ONE of the subatomic particles of the atomic nucleus, i.e. a PROTON or a NEUTRON.
So, in a Nuclear reaction, the total number of nucleons changes.
The two angles would be both 41 degrees.
x in this case would be 14 degrees.
Helium, neon,nitrogen and argon
