Answer:
Im sorry i though this was a joke i don't know I'm sorry:
Hydrogen bonds are stronger than the dipole dipole attraction force present in any molecule.
<h3>What is bonding in molecules?</h3>
Bonding is a type of attraction force which is present between the different atoms or elements of any substance.
- Dipole dipole attraction force is a weak force as compared to the hydrogen bonding and present between any two oppositely charged atoms.
- Hydrogen bond is present between the hydrogen atom and more electronegative atoms like O, S, N and F.
Hence main difference is that hydrogen bond is only present between the hydrogen atom and more electronegative.

Answer:
The mass of the surrounding is 
Explanation:
From the question we are told that
The mass of 
is 
The mass of water is 
The chemical equation for the dissociation process is
The specific heat capacity of the mixture is 
The combined mass of the solution is
The mass of the surround here is the mass of the coffee-cup calorimeter and this contain the mixture ( water and the NaOH ) so the mass of the surrounding is
Answer:
2.835 moles of carbon
Explanation:
By definition, there are 6.022x10^23 atoms (or compounds) in one mole.
Write and use this as a conversion factor:
(6.022x10^23 atoms)/mole
(1.707 x 10^24 atoms of carbon)/((6.022x10^23 atoms)/mole) = 2.835 moles carbon
Answer:
70 mL of 5% HCl and 30 mL of 15% HCl
Explanation:
We will designate x to be the fraction of the final solution that is composed of 5% HCl, and y to be the fraction of the final solution that is composed of 15% HCl. Since the percentage of the final solution is 8%, we can write the following expression:
5x + 15y = 8
Since x and y are fractions of a total, they must equal one:
x + y = 1
This is a system of two equations with two unknowns. We will proceed to solve for x. First, an expression for y is found:
y = 1 - x
This expression is substituted into the first equation and we solve for x.
5x + 15(1 - x) = 8
5x+ 15 - 15x = 8
-10x = -7
x = 7/10 = 0.7
We then calculate the value of y:
y = 1 - x = 1 - 0.7 = 0.3
Thus 0.7 of the 100 mL will be the 5% HCl solution, so the volume of 5% HCl we need is:
(100 mL)(0.7) = 70 mL
Similarly, the volume of 15% HCl we need is:
(100 mL)(0.3) = 30 mL
