Ethanol (C2H5OH) and water (H2O) are both liquids at or near room temperature. When a sample of ethanol is poured into a beaker

containing water, the two liquids. a. Are miscible because each can hydrogen bond with the other. b. Are immiscible because each has strong hydrogen bonds that cannot be broken. c. Are miscible because both are liquids and all liquids are miscible. d. Are immiscible because organic and non-organic compounds cannot mix.

Answer:

a. Are miscible because each can hydrogen bond with the other.

Explanation:

Both ethanol and water are miscible. The reason why they can both mix freely is due to the hydrogen bonds that will form between their molecular structure.

Hydrogen bonds are special dipole-dipole attraction between polar molecules in which hydrogen atoms are directly joined to an electronegative atom.

Ethanol has an hydroxyl group which will bond to form an intermolecular bond with the oxygen and hydrogen on the water molecule. This attraction makes them miscible.

Determine the resulting pH when 12mL if 0.16M HCl are reacted with 32 mL if 0.24M KOH.
TEA [102]

Answer:

pH = 13.1

Explanation:

Hello there!

In this case, according to the given information, we can set up the following equation:

HCl+KOH\rightarrow KCl+H_2O

Thus, since there is 1:1 mole ratio of HCl to KOH, we can find the reacting moles as follows:

n_{HCl}=0.012L*0.16mol/L=0.00192mol\\\\n_{KOH}=0.032L*0.24mol/L=0.00768mol

Thus, since there are less moles of HCl, we calculate the remaining moles of KOH as follows:

n_{KOH}=0.00768mol-0.00192mol=0.00576mol

And the resulting concentration of KOH and OH ions as this is a strong base:

[KOH]=[OH^-]=\frac{0.00576mol}{0.012L+0.032L}=0.131M

And the resulting pH is:

pH=14+log(0.131)\\\\pH=13.1

Regards!

How much heat is required to change the temperature of 100 grams of water from 25 to 55oc?
marysya [2.9K]
Hthe heat required  to change the temperfature  of 100 grams of water  from 25 to 55 c is calculated as below

Q(heat) = M(mass) x C(specific heat capacity) x delta T(change  in temperature)

M= 100 grams
C= 4.18 j/g/c
delta T= 55-25 =30c

Q=100 g x4.814 j/g/c x  30c = 12552  joules

What is the chemical equation for the alpha decay of erbium-144
iren [92.7K]

Answer:

Er-144 -------> Dy-140 + He-4

Explanation:

Alpha decay is the release of a hydrogen nucleus.  So the original atom will decrease the mass by 4 and the atomic number by 2.

How to differ mixture and compound? What are their differences? ​
Roman55 [17]

Explanation:

"Compound: A substance that is made up of more than one type of atom bonded together. 

Mixture: A combination of two or more elements or compounds which have not reacted to bond together; each part in the mixture retains its own properties."
