Answer:

Solubility increases with temperature.

Explanation:

-Increasing temperatures, increases the kinetic energy that allows solvent molecules to more effectively break apart the solute molecules.

-This solute molecules are held together by intermolecular attractions which weakens in higher temperatures.

-Solubility therefore increases with increasing temperatures.

A six pack of your favorite beverage (12 fl. oz. cans, assumed to have the same characteristics as water) is placed in a cooler

nasty-shy [4]

Answer:

$Q = 169 BTU$

Explanation:

As we know that volume is given as

$V = 12 Fl oz$

so it is given in liter as

$V = 12 fl oz = 0.355 Ltr$

now we have six pack of such volume

so total volume is given as

$V = 6\times 0.355 Ltr$

$V = 2.13 ltr$

so its mass is given as

$m = 2.13 kg$

now the change in temperature is given as

$\Delta T = 70 - 34 = 36 ^oF$

$\Delta T = 20^oC$

now the heat given to the liquid is given as

$Q = ms\Delta T$

$Q = 2.13(4186)(20)$

$Q = 1.78 \times 10^5 J$

$Q = 169 BTU$

Two equal charges are separated by 3.7x10^-10m. The force between the charges has a magnitude of 2.37x10^-3 N. What is the magni

Alla [95]

Answer:

Charge on two particles is given as

$q = 1.89 \times 10^{-16} C$

Explanation:

As we know that the electrostatic force between two charges is given by formula

$F = \frac{Kq_1q_2}{r^2}$

so we will have

$q_1 = q_2 = q$

$r = 3.7 \times 10^{-10} m$

$F = 2.37 \times 10^{-3} N$

so we have

$2.37 \times 10^{-10} = \frac{(9 \times 10^{9})(q)(q)}{(3.7 \times 10^{-10})^2}$

$q = 1.89 \times 10^{-16} C$
