Answer : Both solutions contain 
molecules.
Explanation : The number of molecules of 0.5 M of sucrose is equal to the number of molecules in 0.5 M of glucose. Both solutions contain 
molecules.
Avogadro's Number is 
= 
which represents particles per mole and particles may be typically molecules, atoms, ions, electrons, etc.
Here, only molarity values are given; where molarity is a measurement of concentration in terms of moles of the solute per liter of solvent.
Since each substance has the same concentration, 0.5 M, each will have the same number of molecules present per liter of solution.
Addition of molar mass for individual substance is not needed. As if both are considered in 1 Liter they would have same moles which is 0.5.
We can calculate the number of molecules for each;
Number of molecules = 
;
∴ Number of molecules = 
which will be = 
Thus, these solutions compare to each other in that they have not only the same concentration, but they will have the same number of solvated sugar molecules. But the mass of glucose dissolved will be less than the mass of sucrose.

<em>Explanation:An object is in motion when its distance from another object is changing. Whether an object is moving or not depends on your point of view. ... A reference point is a place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point.</em>
Explanation:
The net equation will be as follows.
So, we are required to find 
for this reaction.
Therefore, steps involved for the above process are as follows.
Step 1: Convert K from solid state to gaseous state
, 
= 89 kJ
Step 2: Ionization of gaseous K
, 
= 418 KJ
Step 3: Dissociation of 
gas into chlorine atom
.
, 
= 122 KJ
Step 4: Iozination of chlorine atom.
, 
= -349 KJ
Step 5: Add 
ion and 
ion formed above to get KCl
.
, 
= -717 KJ
Now, using Born-Haber cycle, value of enthalpy of the formation is calculated as follows.
= 89 + 418 + 122 - 349 - 717
= - 437 KJ/mol
Thus, we can conclude that the heat of formation of KCl is - 437 KJ/mol.
Answer:
The correct option is C. The level of organization best represented by the corn plant is : organism, the level of organization directly above organ system organ system
Explanation:
An organism can be described as a living thing made up of organ systems.
Plants are organisms that have levels of organizations similar to animals. Cells in plants make up tissues. There are mainly two types of tissues in plants: the meristematic tissue and non-meristematic tissue.
Just like animals, plants have organ systems. There are two kinds of organ systems mainly in plants: the shoot system and the root system. Hence, option C is the correct option.
Answer:
Because Gay-LUssac's law works only on K scale. To find the answer you must convert C to K
