Answer:
10
Explanation:
Binary search's runtime is proportional to log (base two) of the number of list elements.
1. 2CaS + 2H2O --> Ca(HS)^2 + Ca(OH)^2
2. Au^2S^3 + 3H2 --> 2Au + 3H2S
Answer:
60.0mL
Explanation:
For the process of titration , the formula we use is -
M₁V₁ = M₂V₂
Where ,
M₁ = initial concentration
V₁ = initial volume
M₂ = final concentration
V₂ = final volume .
Hence , from the question ,
The given data is ,
M₁ = 0.050 M
V₁ = 30.0mL
M₂ = 0.025 M
V₂ = ?
Now, to determine the unknown quantity , the formula can be applied ,
Hence ,
M₁V₁ = M₂V₂
Putting the respective values ,
0.050 M * 30.0mL = 0.025 M * ?
solving the above equation ,
V₂ = ? = 60.0mL
Answer:
A vacuum flask is usually used to insulate it's contents… I've used them for a multitude of things ranging from keeping my coffee warm, to keeping liquid nitrogen from evaporating.
The reason these types of flasks are so efficient has to do with their thermodynamic properties. To understand how a vacuum flask works, we need to know the basic properties of a vacuum. Air just like any other molecule is a conductor of heat.
Firstly, a “layer of vacuum” is created around the thermos, it's crucial that the chamber is depressurized*.
