Acetone and water are miscible. Acetone and hexane are also miscible. What is the possible explanation for their miscibilities,

considering that water and hexane are immiscible?

Acetone is miscible because it has a C=O bond, while its C-C-C carbon chain makes it miscible with hexane. However, hexane is non-polar while water is polar, and since the two molecules have different polarities, they are immiscible.

Which statement describes carbohydrates?
seraphim [82]

Answer:

Carbohydrates provide energy to organisms.

Explanation:

Im 100% sure because Carbohydrates can also be defined chemically as neutral compounds of carbon, hydrogen and oxygen. Carbohydrates come in simple forms such as sugars and in complex forms such as starches and fiber. The body breaks down most sugars and starches into glucose, a simple sugar that the body can use to feed its cells

How many moles of HCl are present in 0.70 L of a 0.33 M HCl solution? (molar mass of HCl = 36.46 g/mol)
Vilka [71]

Answer:-

0.231 moles

Explanation:-

From the question we are told that

Volume of HCl solution = 0.70 L

Strength of HCl solution = 0.33 M

Here M stands for molarity. Molarity is the number of moles of the substance present per Litre of solution. So in place of M we can write moles / L

Number of moles of HCl solution = Volume of HCl solution x Strength of HCl solution

= 0.70 L x 0.33 moles / L

= 0.231 moles.

0.231 moles of HCl are present in 0.70 L of a 0.33 M HCl solution

Redo the experiment by clicking on Reset Experiment. Add Ca(NO3)2 to 40 g of Na2CO3 and determine at what point the masses of th
Radda [10]

Answer : The mass of Ca(NO_3)_2  added must be, 61.9 grams

Explanation : Given,

Mass of Na_2CO_3 = 40 g

Molar mass of Na_2CO_3 = 105.9 g/mol

First we have to calculate the moles of Na_2CO_3.

\text{ Moles of }Na_2CO_3=\frac{\text{ Mass of }Na_2CO_3}{\text{ Molar mass of }Na_2CO_3}=\frac{40g}{105.9g/mole}=0.378moles

Now we have to calculate the moles of MgO

The balance chemical reaction will be:

Ca(NO_3)_2+Na_2CO_3\rightarrow CaCO_3+2NaNO_3

From the balanced reaction we conclude that

As, 1 mole of Na_2CO_3 react with 1 mole of Ca(NO_3)_2

So, 0.378 mole of Na_2CO_3 react with 0.378 mole of Ca(NO_3)_2

Now we have to calculate the mass of Ca(NO_3)_2

\text{ Mass of }Ca(NO_3)_2=\text{ Moles of }Ca(NO_3)_2\times \text{ Molar mass of }Ca(NO_3)_2

Molar mass of Ca(NO_3)_2 = 164 g/mol

\text{ Mass of }Ca(NO_3)_2=(0.378moles)\times (164g/mole)=61.9g

Thus, the mass of Ca(NO_3)_2  added must be, 61.9 grams
