Round 89 to 90 then divide by 4. so its 24.
True!
For example:
The atomic mass of carbon is 12.011 (i think) and the weight of carbon is 12. But with C13 and C14 being a little higher, it makes the average higher. Random fact: C14 is used for carbon dating.
Answer:
<u></u>
Explanation:
The current temperature and pressure at <em>STP </em>(Standard Temperature and Pressure) stated by IUPAC are:
- Temperature: 273.15 K (0 °C)
- Pressure: 10⁵ Pa ≈ 0.9869 atm
Using the <em>ideal gas </em>equation, pV = nRT, and the Avogadro constant, you can find the<em> volume occupied by 5.80 × 10²⁰ molecules.</em>
<u>Answer:</u> The concentration of acetic acid in the vinegar is
<u>Explanation:</u>
To calculate the pH of the solution, we use the equation:
We are given:
pH = 2.95
Putting values in above equation, we get:
The chemical equation for the ionization of acetic acid follows:
The expression of for above equation follows:
We are given:
Putting values in above expression, we get:
So, the concentration of acetic acid =
Hence, the concentration of acetic acid in the vinegar is
Yes, a reaction will occur. Potassium chloride react with bromine to produce potassium bromide and chlorine would take place in a boiling solution.
