Answer:
T₂ = 669.2 K
Explanation:
Given data:
Initial pressure = 660 torr
Initial temperature = 26 °C (26 +273 = 299 K)
Final volume = 280 mL ( 280/1000 = 0.28 L)
Final pressure = 940.0 torr
Final volume = 0.44 L
Final temperature = ?
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
P₁V₁/T₁ = P₂V₂/T₂
T₂ = P₂V₂ T₁ /P₁V₁
T₂ = 940 torr × 0.44 L × 299 K / 660 torr × 0.28 L
T₂ = 123666. 4 torr. L. K / 184.8 torr. L
T₂ = 669.2 K
Answer:

Answer:
vinegar is acidic
water should be neutral but people say since it's pH 7,it will be more alkaline
salt solution is acidic
lemon juice is acidic
sugar solution is alkaline
soap is alkaline
Methyl orange will turn red with grapefruit juice.
Methyl orange will turn yellowish orange or lemme say red with oven cleaner
The addition of pure water to methyl orange will not have an effect on the color and the solution will still be around neutral pH and yellow in color.
Explanation:
Working on number 7
