the reduced substance is Cl2.
The Precision of a calculated answer is limited by the least precise measurement used in the calculation is false.
If the average value of different measurements is similar to the correct value of the measurement is said to be accurate and if the value of different measurements is close to each other then it is said to be precise.
The everage value of the different measurements may or not may be the same as exact and the resultant values must be the same as the calculated value for the precision of the result.
Therefore, the Precision of a calculated answer is limited by the least precise measurement used in the calculation is false.

(2) the activation energy of the exothermic reaction
(3) the difference between the potential energy of the products and the potential energy of the reactants
(4) the sum of the potential energy of the products and the potential energy of the reactants
Answer: The correct answer is Option 3.
Explanation:
The net energy absorbed or released in a reaction is known as total enthalpy change of the reaction. It is designated as
It is defined as the difference between the total potential energy of the products and the total potential energy of the reactants. The equation for this is given by:
where,
= Total potential energy of the products
= Total potential energy of the reactants
Hence, the correct answer is Option 3.
B) Cu
C) Fe
D) Sb
Answer;
-Copper (Cu)
Explanation;
-While all metals can conduct electricity, certain metals are more commonly used due to being highly conductive. The most common example is Copper. It is highly conductive which is why it is has been used in electrical wiring.
-Copper is used for electrical wiring because it is a good conductor of electricity. Metal particles are held together by strong metallic bonds, which is why they have high melting and boiling points. The free electrons in metals can move through the metal, allowing metals to conduct electricity.
To find the midpoint M of a line segment with endpoints Q(0,5) and R(2,1), you can use the midpoint formula:
Midpoint M = ((x₁ + x₂) / 2, (y₁ + y₂) / 2)
In this formula:
- (x₁, y₁) are the coordinates of the first endpoint (Q in this case).
- (x₂, y₂) are the coordinates of the second endpoint (R in this case).
Plug in the values:
M = ((0 + 2) / 2, (5 + 1) / 2)
M = (2 / 2, 6 / 2)
M = (1, 3)
So, the midpoint M of the line segment with endpoints Q(0,5) and R(2,1) is (1, 3).
Does anyone understand any of this and how this all works ?
