The answer would be the ability to be tested. If a hypothesis is testable, it would of course lead you to test it. Which, by definition is a new experiment.
Answer:
0.7692 M ≅ 0.77 M.
Explanation:
- It is known that the no. of millimoles of a solution before dilution is equal to the no. of millimoles of the solution after the dilution.
<em>(MV) before dilution = (MV) after dilution.</em>
M before dilution = 2.0 M, V before dilution = 0.25 L.
M after dilution = ??? M, V after dilution = 0.25 L + 0.40 L = 0.65 L.
∴<em> M after dilution = (MV) before dilution/(V) after dilution</em> = (2.0 M)(0.25 L)/(0.65 L) =<em> 0.7692 M ≅ 0.77 M.</em>
Answer:
1. There most not be rotation within the molecule.
2. Two non identical group must be present in the double bonded carbon atom.
Explanation:
This is because cis/ trans isomerism are that exhibit different structural configurations where the atoms are spartially arranged. They are also refered to as geometric isomers. They cannot be interconverted at room temperature because it requires the bonds to be broken and restructured.
Cis shows that the functional groups on present in the same side which trans isomerism show that the functional groups are on opposite sides.
3.6 x 10²³
Explanation:
Given parameters:
Number of cell per body = 60 trillion body cells
Population of the earth = 6 billion
Unknown:
Total number of living human body cells = ?
Solution:
To solve this problem, simply find the product:
Total number of living human body cells = number of cell per body x population of the earth
1 trillion = 1 x 10¹²
60 trillion = 6 x 10¹³
1 billion = 1 x 10⁹
6 billion = 6 x 10⁹
Total number of living human body cells = 6 x 10¹³ x 6 x 10⁹
= 6 x 6 x 10⁽¹³⁺⁹⁾
= 36 x 10²² or 3.6 x 10²³
