To know if an equation is balanced you need to check and see how much of each molecule is on either side of the arrow. Right now you have 1-Ca, 2-H, 2-Cl on the left side of the arrow and 1-Ca, 2-Cl, and 2-H on the right side too. Because all the molecules are equal on both sides this means that the equation is balanced. So in front of the CaCl2 there is an assumed coefficient of 1. The answer is 1.
E0,correctly written as E
, is the <span> standard electrode potential of the cell. This is usually used in the subject, electrochemistry. This is used to measure the difference in potential between two half cells used in an electrochemical cell. The o above signifies that it is at its standard state. </span>
The purpose of an experiment is to determine if the hypothesis is correct or incorrect
<h3>What is an experiment?</h3>
An experiment is a research or test conducted in order to prove or disprove a hypothesis.
An experiment can also be done to answer a question.
A hypothesis is an answer provided to explain an observation without conducting tests to back up the explanation given.
Therefore, an experiment is aimed at determining if a hypothesis is correct or not.

Answer:
the answer is 4778.36
Explanation:
do pi time the radius squared times the height divided by 3
Answer:
[Fe⁺³] = 0.0010 M
[SCN⁻] = 0.0006 M
Explanation:
First we<u> calculate how many moles of Fe⁺³ and SCN⁻ were added</u>, using <em>the given volumes and concentrations</em>:
- Fe⁺³ ⇒ 5.00 mL * 0.0020 M = 0.010 mmol Fe⁺³
- SCN⁻ ⇒ 3.00 mL * 0.0020 M = 0.006 mmol SCN⁻
Now we can <u>calculate the initial concentrations</u>, after <em>calculating the new volume of the solution</em>:
- New volume = 5.00 mL + 3.00 mL + 2.00 mL = 10.00 mL
- [Fe⁺³] = 0.010 mmol / 10.00 mL = 0.0010 M
- [SCN⁻] = 0.006 mmol / 10.00 mL = 0.0006 M
