Answer:In a sample of BrF the strongest interparticle force is the dipole-dipole force.

While Kr is the dispersion force.

And H2SO4 is hydrogen bonding

Explanation:

Brf is polar with a known dipole moment of 1.4D,dipole - dipole force and dispersion force are both present,the dipole-dipole force is the strongest interparticle force action on Brf considering its high boiling points

The bond formed by Kr will be non polar due to greater atomic size and low electronegativity.The force of attraction between the non polar is the dispersion force which is the strongest.

H2SO4 has a great polarity with a very strong hydrogen bonding.

How many liters of 3.5 M solution can be made using 23 moles of LiBr *must show work to get credit*

MrMuchimi

<u>Answer:</u> 6.57 L of solution can be made.

<u>Explanation:</u>

Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:

$\text{Molarity of solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (L)}}$ .....(1)

Given values:

Molarity of LiBr = 3.5 M

Moles of LiBr = 23 moles

Putting values in equation 1, we get:

$3.5mol/L=\frac{23mol}{\text{Volume of solution}}\\\\\text{Volume of solution}=\frac{23mol}{3.5mol/L}=6.57L$

Hence, 6.57 L of solution can be made.

How many joules of heat is lost when a 64 g piece of copper cools from 375 oC to 26 oC? The specific heat of copper is 0.38 J/go

Svetlanka [38]

Answer: 8500 J lost or -8500 J

Explanation:

q=cmt

t=375-26

t=349

q=0.38(64)(349)

q=8487.68 J

Answer must have 2 sig figs, which means it rounds to 8500 J.
