Answer:
Units of k = 
Explanation:
According to the law of mass action, the rate of a reaction is determined as the product of the active concentration of the reactant each raised to their experimentally determined coefficients which are known as order.
So, given that:-
Rate = k [X]
Rate of the reaction is also, the change in the concentration per unit time. So, the units of rate of a reaction is :- M/s
Units of [X] = M
So,
![k=\frac{Rate}{[X]}=\frac{M/s}{M}=s^{-1}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7BRate%7D%7B%5BX%5D%7D%3D%5Cfrac%7BM%2Fs%7D%7BM%7D%3Ds%5E%7B-1%7D)
Units of k = 
Answer:
The distance the plane flies.
Explanation:
This is the dependent (outcome) variable because it is changing depending on the number of paper clips that are added to the plane.
Answer:
11.31 g.
Explanation:
Molarity is defined as the no. of moles of a solute per 1.0 L of the solution.
M = (no. of moles of solute)/(V of the solution (L)).
<em>∴ M = (mass/molar mass)of NaCl/(V of the solution (L)).</em>
<em></em>
<em>∴ mass of NaCl remained after evaporation of water = (M)(V of the solution (L))(molar mass)</em> = (0.45 M)(0.43 L)(58.44 g/mol) = <em>11.31 g.</em>

If the Arctic became completely ice-free and phytoplankton productivity levels were maintained, Arrigo and his colleagues calculated that the new carbon sink could in theory absorb an extra 160 million tonnes of carbon each year.
