vazorg [7]
<span>The answer is C. The volume decreases. A scuba diver at the surface of the sea takes a deep breath and fills her lungs with 6 liters of air. The pressure in her lungs is 1 atm. She then dives down ten meters, without inhaling or exhaling, until the pressure of the air in her lungs is 2 atm. According to Boyle’s law,  the air in her lungs decreases as she dives down.  </span>Boyle's Law<span> is the gas </span>law which states that in a closed space, pressure and volume are inversely related. As pressure increases, volume decreases, and vice versa.

How many lone pairs are on the central atom in GeH4?
Step2247 [10]
It shouldn't have any lone pairs since it is a tetrahedral structure. Ge has 4 valence electrons. Each H has 1 valence electron. Therefore, each H valence electron will pair with each valence electron on Ge.

Molarity = moles / liter

a) M = 2/4 = 0.5 M

b) Moles = 4/(30 + 16 + 1)
= 0.085
M = 0.085 / 2 = 0.0425 M

c) Moles = 5.85 / (23 + 35.5)
= 0.1
M = 0.1 / 0.4
= 0.25 M

What is the pH of a solution with an H3O+ concentration of 5.67 x 10-4 M?
Valentin [98]

Answer:

<h2>3.25 </h2>

Explanation:

The pH of a solution can be found by using the formula

pH = - log [ { H_3O}^{+}]

From the question we have

ph =  -  log(5.67 \times  {10}^{ - 4} )  \\  = 3.2464

We have the final answer as

<h3>3.25 </h3>

Hope this helps you
