Answer:
4.07 × 10⁹ mL
Explanation:
Step 1: Given data
Length of the pool (L): 60.0 m
Width of the pool (W): 35.0 m
Depth of water in the pool (D): 6.35 ft
Step 2: Convert "D" to m
We will use the relationship 1 m = 3.28 ft
Step 3: Calculate the volume of water (V)
We will use the following expression.
Step 4: Convert "V" to mL
We will use the relationship 1 m³ = 10⁶ mL.
Answer is: chemical.
Making a pancake from batter is chemical change (chemical reaction), because new substances are formed, the atoms are rearranged and the reaction is followed by an energy change.
Batter is thin dough that is poured into a pan to make pancakes.
In physical change, the same substance is present before and after the psysical change, just with different form or state of matter.
<u>The </u><u>scientific community </u><u>may act somewhat on restricted government </u><u>financing</u><u> circumstances throughout two ways:</u>
- Source for further money.
- Adjust this same scale and complexity of the investigation.
<u>Source for further money:</u>
- A researcher anyone who has restricted equipment and materials to finish an investigation might cooperate with certain other scientists as well as establish networking to exchange resources, thoughts, and behaviors for the survey's completion.
<u>Adjust this same scale and complexity of the investigation:</u>
- To decrease costs, the researchers might measure the study up by decreasing the levels initially intended for the investigation.

Answer:
The hydronium ion concentration can be found from the pH by the reverse of the mathematical operation employed to find the pH. [H3O+] = 10-pH or [H3O+] = antilog (- pH) Example: What is the hydronium ion concentration in a solution that has a pH of 8.34? On a calculator, calculate 10-8.34, or "inverse" log ( - 8.34).
