Bohr changed the model of the atom by proposing that electrons travelled in circular orbits with specific energy levels.
About 6.5x10^22 molecules.
(5g C2H5OH)x(1 mol C2H5OH/46g C2H5OH)x(6.02x10^23 molecules C2H5OH/1 mol C2H5OH)=(3.01E24)/46=6.5x10^22.

Answer:
Multiply 1.25 by 0.04 and divide the result obtained by 1,000
Explanation:
Given: [1 gram = 0.04 ounce, 1 liter = 1,000 milliliter]
1.25 x 0.04 = 0.05 oz
Therefore, 0.05 per 1,000 milliliter
0.05 ÷ 1,000 = 0.00005 oz
Therefore, the density of the gas is 0.00005 oz/mL
Hope this helps! :)
Answer:
Protons and neutrons are made up of smaller subatomic particles. When protons or neutrons get close enough to each other, they exchange particles (mesons), binding them together. Once they are bound, it takes considerable energy to break them apart.
Answer:
At 3 mmHg and 50°C water exists as a <em><u>gas</u></em>.
