50,290,000 KM
50,290,000*1000= 5290000000 meters
Answer:
Option (C) 3
Explanation:
The pH scale is a scale that ranges from 0 to 14. The pH reading has various notifications. These notifications are as follow:
1. If the pH reads between 0 and 6, then the solution is acidic.
2. If the pH reads 7, then the solution is neutral.
3. If the pH reads between 8 and 14, then the solution is basic.
With the above information, option C is the correct answer to the question.
Answer
I think it might be B
Explanation
Answer:
mass of water is 7.43 g
Explanation:
q = mc∆T
qsteam = 100 g × 1.864 J/(g °C) × (110 – 100) °C = 1864 J
qwater = mwater× 4.184 J/(g °C) × (95 – 35) °C = mwater× 251.04 J/g = qsteam = 1864 J
mwater = 1864 J / 251.04 J/g = 7.43 g
Answer;
A decrease in the vapor pressure of the liquid.
Dissolving a solute such as potassium hydroxide in a solvent such as water results in a decrease in the vapor pressure of the liquid.
Explanation;
The vapor pressure of a liquid is the equilibrium of a vapor above its liquid.
In other words it is the pressure of the vapor resulting from the evaporation of a liquid above a given sample of the liquid in a closed container.
The vapor pressure of a liquid in a closed container depends on the temperature.
