Answer:
The time taken the same amount of ammonia to effuse through the same barrier under the same conditions is 2.76 minutes.
Explanation:
Let the volume of the helium gas be = V
Time taken by the helium gas = t = 1.34 min
Effusion rate of helium gas = 
If V volume of ammonia effuse through same porous barrier the effusion rate of ammonia gas will be given as:
Using Graham's Law.
This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows the equation:
Molar mass of helium gas = M = 4 g/mol
Molar mass of ammonia gas = M' = 17 g/mol
The time taken the same amount of ammonia to effuse through the same barrier under the same conditions is 2.76 minutes.
Answer:
H₂O (water)
Explanation:
The reaction given is the glucose combustion inside the cells. During the combustion, it will be formed carbonic gas, water and energy.
The oxygen molecule is split in their two atoms of O. The element which has 1 proton and 1 electron is the hydrogen (H). So, when hydrogen reacts with oxygen, they form water (H₂O).
Answer:
The solution to the given problem is done below.
Explanation:
a)
i) =( 0.002 μg / L )( 1mg / 1000 μg )( 1L / kg )( 1000 mil / 1 billion) = 0.002 ppb
ii) =( 0.002 μg / L )( 1mg / 1000 μg )( 1L / kg )( 1,000,000 mil / 1 trillion) = 2 ppt
iii) =( 0.002 μg / L )( 1 mole / 540g ) = 3.7 x 
μM.
b)
i) =( 0.002 μg / g ) = 0.002 ppm
ii) In solids, ppb = μg/kg
=( 0.002 μg / g )( 1000 mil/ 1 billion) = 2 ppb
Plants can adapt to their environment for example algae is soft and can survive being moved or broken this is perfect for living on top of water were animals often swim and shake the surface.
Explanation:
More quickly a reactant will disappear, the more quickly it will result in the formation of products. This means that consumption or disappearance of reactants determines the rate of a reaction because only then products will be formed.
Thus, we can conclude that measuring how quickly a reactant disappears is one way to measure the rate of the reaction.
