More dissolved oxygen is present in water with a lower temperature compared to water with a higher temperature. The reason for this inverse relationship between dissolved oxygen and temperature is that the solubility of a gas in a liquid is an equilibrium phenomenon.
Answer:
a mixture that is the original
Explanation:
like tea with out sugar or coke-cola with the cherry flavoring
Answer:
The ionic compound NaCl has a Face Centered Cubic unit cell
The site for atoms are Face, center and Edges corner.
Effective number of atoms
Na+
1centers + 12edges x
= 4 Na+
Cl-
6face x
+ 
x8 corners = 4Cl-
This is just one unit cell effective atom, there are thousand's of such unit cells are combined to form one such structure of NaCl. The real formula of NaCl is Na4Cl4 but for simplicity we use empirical formula that is NaCl.
Answer:
1.71atm
Explanation:
The following were obtained from the question:
V1 (initial volume) = 6L
P1 (initial pressure) = 1atm
V2 (final volume) = 3.5L
P2 (final pressure) =?
Using the Boyle's law equation:
P1V1 = P2V2, the final pressure can be obtained as follow:
P1V1 = P2V2
1 x 6 = P2 x 3.5
Divide both side by 3.5
P2 = 6/3.5
P2 = 1.71atm
The final i.e the new pressure inside the piston is 1.71atm
Answer:
C.
Explanation:
A chemical change happens when one chemical substance is transformed into one or more different substances, such as when iron becomes rust.
