Answer:
8.3334%
Explanation:
You have two masses. To find the percent of sodium chloride in water by mass, you divide the mass of NaCl by water. First, make both units the same. Easiest is to convert kg into g. 1.5kg = 1500g
125g NaCl/1500g H2O = 0.0833333333 ==> 8.3334%
Answer: covalent bond
Explanation: The carbon-hydrogen bond is a bond between carbon and hydrogen atoms that can be found in many organic compounds.
Answer:
A reaction is spontaneous if ΔG is negative.
Explanation:
- The change in free energy (ΔG) is the difference between the heat released during a process and the heat released for the same process occurring in a reversible manner.
- The sign of ΔG gives an indication for the spontaneity of the reaction:
If ΔG is negative, the reaction is spontaneous.
If ΔG = zero, the reaction is at equilibrium.
If ΔG is positive, the reaction is non-spontaneous.
Answer:
closed container of N2O4 and NO2 is at equilibrium. NO2 is added (increasing the concentration) to the container.
N2O4 (g)
Answer:
The indepandent variable is wether its hot or cold water, so the tempurature of the water. The dependant variable is how much sugar disolves.
Explanation:
The indepandant variable is what changes or has a direct affect on the depandant. The depandant is what is being mesured or tested.
