Answer:
Cobalt chloride= D cobalt(111) chloride
<em>[H⁺] = 1,7×10⁻⁹ mol/dm³</em>
pH = -log[H⁺]
pH = -log[<span>1,7×10⁻⁹]
<u>pH = 8,77</u>
pH + pOH = 14
pOH = 14-8,77
<u>pOH = 5,23
</u>:)</span>
D. Should be correct- the other ones don’t make sense
Answer:
Healthy Eating — Make sure your child's caregivers offer healthy snacks and meals. Consider other influences. Just as they do for you, your children's friends and the media can also affect healthy choices. Some TV, online, and other ads try to persuade children to consume high-fat foods and sugary drinks.
As discussed in Raymond Chang’s introductory textbook “Chemistry,” a mole is a measure of molecules, equal to approximately 6.022x10^23 molecules, where the caret ^ refers to exponentiation. Using the ideal gas formula, you can find the number of moles of carbon dioxide (CO2) in a container if you know the other needed parameters and conditions. Above 150 pounds per square inch (PSI), or around 10 times normal atmospheric pressure, the ideal gas formula starts losing accuracy and the Van der Waals formula becomes increasingly preferable.
