Answer:
Propane tanks are most commonly referred to by their water capacity volume, and propane tanks are normally filled to 80% of its water capacity. For example, a 120-gallon tank will hold approximately 100 gallons of propane when completely full. Since propane is stored in a liquid state under pressure, it needs room to
Answer: You can probably go onto <em><u>You Tube and find that answer!</u></em> Just be <u><em>detailed in your search!</em></u> Hope this helps!
Explanation:
Just Simple Physics :P
When the heat lost by water = heat gained by ethanol
∴( M* C * ΔT )w = (M*C*ΔT ) eth
when Mw mass of water = 40 g
C specific heat of water = 4.18
ΔT = (70- Tf)
and M(eth) mass (ethanol) = 40 g
C specific heat of ethanol = 2.44
ΔT = (Tf - 10 )
by substitution:
40* 4.18 * (70 - Tf) = 40 * 2.44 * (Tf-10)
∴Tf = 47.9 °C
<u>Answer:</u> The correct answer is Option B.
<u>Explanation:</u>
There are 3 subatomic orbitals which are present in an atom:
1. Protons: These sub-atomic particles are positively charged and are found in the nucleus.
2. Electrons: These sub-atomic particles are negatively charged and are found in the orbitals around the nucleus.
3. Neutrons: These sub-atomic particles carry no charge and are known as electrically neutral species. These particles are found in the nucleus.
From the above information, the answer to this question is Option B.
Scientists finally found the reason for the periodicity of the elements: Valence electrons. And so the table became known as the Periodic Table
