Moles of water atoms = mass/molecular weight = 105/18 = 5.83 mol. Number of moles of hydrogen in water = 2 x moles of water = 11.66. Number of H atoms in water = moles of hydrogen x 6.02 x 10^23 = 7.019 x 10^24 ~ 7.02 x 10^24 atoms. Hope this helps.
Answer:
number 7 is GROWTH
number 8 is TARGET CELLS
number 9 is pituitary gland
Here we have to get the reason for continues changing of the atomic model over the past 200 years.
The reason for changing the atomic model is-The results of further experimentation helped to revise and improve the model.
The development of atomic model occurred step-wise as given below-
1. Rutherford atomic model, which explained the result of electrical neutrality of atoms by discovering the nucleus of atom, but it cannot explain the stability of accelerated charge particle i.e. electron.
2. The concept of radiation was later explained by Planck's quantum theory.
3. After this Bohr introduce another concept of atomic model which can explain the stability of the electron and also a part of the spectrum of the atom, but it has the demerits on the fine structure of the atom and heavier elements.
4. Sommerfeld extended the Bohr's theory, which gave the light on the elliptical orbits of a certain orbit.
5. After this to explain the wave-particle duality of the electron, the wave mechanical concept was proposed by deBroglie's, which further extended to the uncertainty to localize the electron and its velocity at a time which is Heisenberg uncertainty principle.
6. Later the quantum mechanical approach to explain the atomic model Schrodinger proposed equation which effectively explain most of the phenomenon of the atoms.
Chemical equation of the reaction between citric acid and baking soda:
Ratios
Citric Acid Baking soda -> Sodium Citrate Water Carbon Dioxide
C6H8O7 CO2
1 mole 3moles
Molecular masses
Citric acid
6*12 + 8*1 + 7*16 = 192 g/mole
Carbon dioxide
12 + 2*16 = 44 g/mole
Proportion carbon dioxide / citric acid
3 * 44 g of carbon dioxide / 192 g of citric acid
132 g of carbon dioxide / 192 g of citric acid
13.00 g of citric acid * [132 g of carbon dioxide / 192 g of citric acid] = 8.94 g of carbon dioxide.
Answer: 8.94 grams.
I think the answer is yes
