Describe an experience you've had making or building something where the amount of each ingredient or building block came in fix

ed ratios.
my answer:
When baking cookies, I need to put in 2 eggs for every 1 cup of flour. That makes one batch. If I want to make 2 batches, then I will need to double my ratio

Is that a correct answer???

The answer is not correct.

If you need <span>2 eggs for every 1 cup of flour to makes one batch of cookie, you can put it into an equation look like this:
2 eggs + 1 cup of flour ==> 1 batch of cookie

If you want to make 2 batches, the equation would be:
</span>4 eggs + 2 cup of flour ==> 2 batch of cookie
<span>
The ratio of 2:1:1 is the same as 4:2:2. Only the amount that increased twice, but the ratio is the same. You don't need to double the ratio, but double the amount.</span>

Which of the following is true for the equilibrium constant of a reaction?
CaHeK987 [17]

Answer:

The correct answer is <em>It is a ratio of the concentrations in a reaction.</em>

Explanation:

⇒ It is a ratio of the concentrations in a reaction.

This sentence is true because the equilibrium constant is calculated from the product of the concentration of the reaction products divided into the product of the concentrations of the reactants, each concentration raised by the stoichiometric coefficient. For example, for the following reaction:

aA + bB → cC + dD

The equilibrium constant is expressed as:

K = \frac{[C]^{c}[D]^{d}  }{[A]^{a} [B]^{b} }

⇒ It remains the same at different temperatures.

The sentence is false because the equilibrium constant changes with the temperature. In general, an endothermic reaction is favored by the increment of temperature (the equilibrium shifts to the right side) and disfavored with the decrease in temperature (shifts to the left).

⇒ It is represented by the symbol H.

This sentence is false because the equilibrium constant is represented with the letter K.

⇒ Its value is always close to 1.

It is not true because the equilibrium constant can be a number below or above 1.

K < 1 ⇒ there is more concentration of reactants at equilibrium

K > 1 ⇒ there is more concentration of products at equilibrium
