Models are usually approximations, too simple and sometimes unrealistic.
Explanation:
A model is an abstraction of the real world. Models are used by scientists to mimic and gain better insights into how the real world looks like to a greater degree of accuracy. Here are some set backs of models;
- Limitations due to parameters that can be modeled; it is nearly impossible to incorporate all the elements of the real world into a model. A scientist may have limited resources to integrate different data sets to perfectly have a good picture of the real world.
- Models are approximations: the fact that models are not exact can be worrisome. Questions like to what extent are these scenarios rounded can be very difficult to come by with and this can spoil a good research.
- Over simplicity: most times when a model proves too complex to work with, some parameters are left out and this can cause a good model to be watered and not portray the real world at all.

Since each ml of water weights 1 g, 0.1 liters of water = 100 grams. As well, "kilo" means "thousand". So 1 kilogram (kg) = 1000 grams. This means 100 g = 0.1 kg.
Answer:
H2O is the only thing that can be added.
Answer : Option B) When the equilibrium constant is large.
Explanation : The expression for an equilibrium constant is expressed as the product of the concentrations of the reaction products in the numerator and the product of the concentrations of the reactants in the denominator.
Each of the concentrations are raised to the power of their respective stoichiometric coefficients in the reaction.
When the equilibrium is large the products are favored over the reactants, as concentration of products are directly proportional to the equilibrium constant.
The expression of equilibrium constant is given by
K = ![\frac{[products]^{a}}{[reactants]^{b}}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%5Bproducts%5D%5E%7Ba%7D%7D%7B%5Breactants%5D%5E%7Bb%7D%7D)
where K - equilibrium constant;
a - co-efficient of product; and
b - co-efficient of reactant.
Even though the numbers are in scientific notation, they are still just numbers. Essentially the question is as simple as "An apple weighs an ounce, how much do 35 apples weigh?". So all you have to do is multiply.
