I believe that the answer is A i could be wrong though.
Answer:
A pure substance consists of a single element or compound. Iron is formed only of iron (Fe) atoms; table salt is formed only by sodium chloride (NaCl) molecules. A mixture, however, is made up of different compounds and/or elements.
Explanation:
Answer: The correct answer is option D.
Explanation:
Mass of the NaCl = 225 g
Volume of the solution ,V = 0.25 L
15.4004 mol/L is the molarity of the solution. The most closest option to our answer is option D.
The new temperature is 337.21 K when the pressure was reduced to 101.3 kPa from 150.2 kPa at 500 K.
Explanation:
Data given:
volume of the container = 100 ml
initial pressure on the container P1 = 150.2 kPa
Initial temperature of the container, T1 = 500 K
final temperature of the container, T2 = ?
Final pressure on the container P2 = 101.3 kPa
from the data provided, we will use Gay Lussac's law to calculate the final temperature:
rearranging the equation,
T2 =
Putting the values in the equation:
T2 =
T2 = 337.21 K
thus, the final temperature of the container is 337.21 K
