The correct answer to this question is 43.2 g. The mass of the glucose in one mole is calculated and then compared. First, one must identify that there are : 12 H = 1.0079g x 12 =12.0948 g , 6 C = 12.011g x 6 = 72.066 g , and 6 O = 15.9994g x 6 = 95.9964 g .
Once we have these figures, we must add and find the mass of glucose in one mole. One mole glucose is 180.157 g. Knowing that we ...

The reason why a black box can survive a plane crash even when other parts of the plane have been destroyed is that it is designed specifically to survive high temperatures and immense pressure. While the devices that make up a black box can be destroyed if they come in contact with water, they have been designed to withstand long periods in water.
For instance, a black box can ...

The answer to this question is the color black. Although every object can absorb and emit electromagnetic radiation, what determines the rate of heat transfer of such an object is its color. In other words, the rate of heat transfer of an object depends on its color.
This means if you have the same object in different colors, the object with black will absorb and radiate more ...

The chemical substance with the highest PH has been proven to be Sodium hydroxide, which has a chemical formula of NaOH. Sodium is actually known to be a basic element. Plus the fact that hydroxyl substances tend to be more of a base in nature.
This simply means that when this compound is tested on the PH scale, it has a PH value of 14. PH value of 14 is actually the highest value of ...

Acids are known to be corrosive substances, really. On the PH scale, these substances called acids would have values less than 7. We tend to be thinking the strongest acid would have a PH value of 1, but let's just check together first.
To start with, hydrofluoric is considered by some to be the strongest acid, but that is not so. The strongest acid is actually referred to as a ...

In a solution where salt is the solute and water is the solvent, the reaction or change would be considered a physical change. This is simply because there is relatively no chemical reaction that takes place in this mixture. Another major reason why we can consider it a physical change is because the solution can still be separated again.
If the solution is taken through the ...

Homogeneous substances or mixtures are always considered to be pure substances or mixtures. They can be explained as mixtures that have a single phase. That means when you mix them together; they are evenly mixed, that you cannot identify the difference between them, and you can also not separate them physically.
For example, the mixture of kerosene and petrol is a homogeneous ...
