The correct option is D.
When dissolving a substance in a solvent, stirring the solution will increased the rate at which the substance dissolved. This is because, when one stirs a solution, it exposes more surface area of the solute to the solvent, thus, increasing the interaction between the solute and the solvent. The higher the quantity of the solute that is exposed to the solvent, the higher the rate of dissolution of the solute.
<span>If there are 15 mL in 1 tablespoon, then 3 tablespoons should have triple the volume as originally stated.
Note in all of the four choices, the units simplify to mL because tbsp x ml/tbsp = mL (tbsp/tbsp = 1)
The second and third choice give ultimately the same, incorrect value. The fourth option gives an incorrect fraction - there are not 15 mL for every tablespoon. The correct answer is 1 tbsp x 15mL/3tbsp</span>
D. there is one atom of sulfur and three atoms of oxygen
Answer:
A 400,000 kg object and a 100,000,000kg object
Explanation:
The objects with the most mass between them will have the greatest gravitational attraction.
This is why the last option is the right choice.
The reason for this is based on the Newton's law of universal gravitation which states that:
"the gravitational force of attraction between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them".
So, the more the mass, the greater the gravitational attraction between two bodies.
Answer:
0.50 M is the molar concentration of
.
Explanation:
The equilibrium constant of the reaction = 

Equilibrium concentration of
= 0.050 M
![[NO_2]=0.050 M](https://tex.z-dn.net/?f=%5BNO_2%5D%3D0.050%20M)
Equilibrium concentration of
= ?
![[N_2O_4]= x](https://tex.z-dn.net/?f=%5BN_2O_4%5D%3D%20x)
The equilibrium constant of the reaction is given aSL:
![K_c=\frac{[NO_2]^2}{[N_2O_4]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BNO_2%5D%5E2%7D%7B%5BN_2O_4%5D%7D)


0.50 M is the molar concentration of
