answer:
as per the formula of given carbohydrate the answer is 15 moles
explanation:
- 1 mole carbohydrate contains 6 moles water
- 2.5 moles contain 6 X 2.5 = 15 moles
Answer:
1.73 atm
Explanation:
Given data:
Initial volume of helium = 5.00 L
Final volume of helium = 12.0 L
Final pressure = 0.720 atm
Initial pressure = ?
Solution:
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
P₁ × 5.00 L = 0.720 atm × 12.0 L
P₁ = 8.64 atm. L/5 L
P₁ = 1.73 atm
Answer:
It is always twice the value of the actual yield.
Explanation:
Answer:
28.43 min
Explanation:
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
Given that:
The rate constant, k =
min⁻¹
Initial concentration
= 0.1 M
Final concentration
=
M
Time = ?
Applying in the above equation, we get that:-




Air moves from
high(pressure)the regions at the
poles(d0)
