The answer is true. A liquid boils when its vapor pressure equals the pressure of the atmosphere. At this point, vapor can now readily escape from the liquid phase because it has an equal pressure now with its surrounding which, basically, is in the vapor phase.
Answer:
143.03%
Explanation:
You find percent yield by dividing actual yield over theoretical yield and then multiplying by 100
I think it is a white dwarf star
Answer: A. There are more reactants than products at equilibrium.
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as 
For a general chemical reaction:
The expression for is written as:
![K_{eq}=\frac{[C]^c[D]^d}{[A]^a[B]^b}](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5Cfrac%7B%5BC%5D%5Ec%5BD%5D%5Ed%7D%7B%5BA%5D%5Ea%5BB%5D%5Eb%7D)
There are 3 conditions:
When 
; the reaction is product favored.
When 
; the reaction is reactant favored.
When 
; the reaction is in equilibrium.
From the above expression, the equilirbium constant is directly dependent on product concentration. Thus, more is the concentration of product, more will be the equilibrium constant.
The values of less than 1 , means the reactant are more than the products.
Answer: The magnesium 24, 25, and 26 atoms are isotopes because they all have the same number of protons but they have different mass numbers
Explanation: isotopes of an element have the same number of protons but different mass number. So for magnesium 24, the number of protons is 12 and the number of neutrons is 12.
For magnesium 25, the number of protons would still be 12 but the neutrons would be 13.
Magnesium 26, the number of protons would be 12 and neutrons number is 14
