Answer:
485 K
Explanation:
Step 1: Given data
- Initial pressure (P₁): 125 atm
- Initial temperature (T₁): 303 K
- Final pressure (P₂): 200 atm
- Final temperature (T₂): ?
Step 2: Calculate the final temperature of the gas
Assuming constant volume and ideal behavior, we can calculate the final temperature of the gas using Gay Lussac's law.
P₁/T₁ = P₂/T₂
T₂ = P₂ × T₁/P₁
T₂ = 200 atm × 303 K/125 atm = 485 K
Answer is: mass of calcium hydroxide is 46.98 grams.
Balanced chemical reaction: CaO + H₂O → Ca(OH)₂.
m(CaO) = 35.55 g.
n(CaO) = m(CaO) ÷ M(CaO).
n(CaO) = 35.55 g ÷ 56 g/mol.
n(CaO) = 0.634 mol; limiting reactant.
m(H₂O) = 125 mL · 1.000 g/mL.
m(H₂O) = 125 g.
n(H₂O) = 125 g ÷ 18 g/mol.
n(H₂O) = 6.94 mol.
From chemical reaction: n(CaO) : n(Ca(OH)₂) = 1 : 1.
n(Ca(OH)₂) = 0.634 mol.
m(Ca(OH)₂) = 0.634 mol · 74.1 g/mol = 46.98 g.
Answer: The molarity of the base solution is 0.22 M.
Explanation:
According to the neutralization law,
where,
= molarity of
solution = 0.1994 M
= volume of
solution = 38.87 ml
= molarity of
solution = ?
= volume of
solution = Final reading - Initial reading = 36.18 - 1.16 = 35.02 ml
= valency of
= 1
= valency of
= 1
Therefore, the molarity of the base solution is 0.22 M.
Most of the light passes through glass but none of the light passes through metal.
Answer:Climate is defined as the average state of everyday's weather condition over a period of 30 years.[1][2] It is measured by assessing the patterns of variation in temperature, humidity, atmospheric pressure, wind, precipitation, atmospheric particle count and other meteorological variables in a given region over long periods of time. Climate differs from weather, in that weather only describes the short-term conditions of these variables in a given region.
