How could you put the understanding of the size of a drop of water to good use in Chemistry?

1 answer:

7 0

Raindrops start to form in a roughly spherical structure due to the surface tension of water. This surface tension is the "skin" of a body of water that makes the molecules stick together. The cause is the weak hydrogen bonds that occur between water molecules

Once of the skills necessary for this experiment is dilution. If you have 1.95 mL of .806 M bleach, what will be the new concent

aleksley [76]

<u>Answer:</u> The concentration of diluted bleach solution is 0.0157 M

<u>Explanation:</u>

To calculate the molarity of the diluted solution, we use the equation:

$M_1V_1=M_2V_2$

where,

$M_1\text{ and }V_1$ are the molarity and volume of the concentrated bleach solution

$M_2\text{ and }V_2$ are the molarity and volume of diluted bleach solution

We are given:

$M_1=0.806M\\V_1=1.95mL\\M_2=?M\\V_2=100mL$

Putting values in above equation, we get:

$0.806\times 1.95=M_2\times 100\\\\M_2=\frac{0.806\times 1.95}{100}=0.0157M$

Hence, the concentration of diluted bleach solution is 0.0157 M

Glucose (c6h12o6) has a single carbonyl group (-c=o) in its linear form. based on the number of oxygen atoms in glucose, how man

sveta [45]

Glucose is a hexose monosaccharide. It is one of the three major monosaccharides along with fructose and galactose. These are carbohydrates with a general formula of Cₓ(H₂O)ₓ, where x could be any number.

Now, you don't have to know the structural formula of the glucose to answer this. Just account all the elements in the glucose. You know that there are 6 oxygen atoms all in all. One of them belongs to the single carbonyl group. Consequently, that would mean that the remaining 5 oxygen atoms bond with hydrogen atoms to form 5 OH groups.

Just to be sure let us refer to the structural formula of glucose shown in the picture. It indeed has 5 OH groups.
