Answer:
The Boiling Point would be below a hundred degrees on a mountain than at sea level.
Explanation:
The Boiling Point is below a hundred degrees, because the air pressure at high altitudes is very low. ( -- < 100)
The Boiling Point for at sea-level would-be a hundred degrees because the air pressure is very high at lower altitudes.
First Model: is shown below, and it shows that the motion of thermal energy particles are moving fast when<u> below 100</u> degrees ( -- < 100).
Second Model: is shown below, and it shows that the motion of thermal energy are moving fast when <u>at 100</u> degrees (--- = 100)
Hope this helps!
Answer:
20.2 °C
Explanation:
When the pressure and number of moles are constant, Charles's law may be used to solve for temperature:
T₁/V₁ = T₂/V₂ >> T₂ = T₁ (V₂/V₁)
Expressions for the volumes can be substituted and simplified:
T₂ = T₁ (V₂/V₁) = T₁ (4/3πr₂³/4/3πr₁³) = T₁ (r₂³/r₁³)
Substituting in values in the equation (where the radius r is half of the diameter) gives:
T₂ = T₁ (r₂³/r₁³) = (19.0°C) x ((51.0cm/2)³/(50.0cm/2)³) = 20.2 °C
Because its more soft then other metals
and other metals lose their color because they react with oxygen but gold doesn't react with oxygen
Answer:
The Answer is B
Explanation:
The answer on this problem is b because I got it wrong then b on this question was the right answer.
The Iron (III) ion is
The sulfate ion is
Thus when forming the compound iron (iii) sulfate you would need three sulfate ions bonded to two iron ions in order to fill the valency requirement
∴ the formula would be Fe₂(SO₄)₃
Whenever you are adding a number to a radical you must bracket it.
