False, a physical change means that the property of matter will change size, shape, color, or density. These are all examples of physical change.
Answer:
0.225M
Explanation:
Step 1:
Data obtained from the question. This includes:
Volume of the stock solution (V1) = 125mL
Molarity of the stock solution (M1) = 0.90 M
Volume of the diluted solution (V2) = 125 + 375 = 500mL
Molarity of the diluted solution (M2) =..?
Step 2:
Determination of the molarity of the diluted solution.
This is obtained by using the dilution formula as follow:
M1V1 = M2V2
0.9 x 125 = M2 x 500
Divide both side by 500
M2 = (0.9 x 125) /500
M2 = 0.225M
Therefore, the molarity of the diluted solution is 0.225M
Answer:
<h3>Plants need oxygen because plants are made living cells which need to perform cellular respiration to get the energy they need to function. Admittedly, needing to perform cellular respiration alone does not mean that consuming oxygen is required - many (micro)organisms use fermentation or anaerobic respiration.</h3>
