Answer:
[OH⁻] = 0.002 M
Explanation:
<u>The definition of pOH</u> is similar to the definition of pH:
This means that with a <u>given pOH value</u>, the calculation of [OH⁻] is a matter of algebra:
To remove the logarithm we increase 10 by the power of the pOH:
=[OH⁻]
Well in my experience with Solar Eclipses is that before it starts or before it is covering the moon is covering the sun there is like a shadow on one side of the sun and after the hours or minutes go by all around you everything is getting darker and a little colder than it was a few moments ago so what it would look like is something is in front of the sun or its like the moon got so close to the sun that it just blocked it and also some of the sun's rays surround the moon.<span />
The balanced reaction that describes the reaction between hydrogen and chlorine to produce hydrogen chloride is expressed H2 + Cl2 = 2HCl. Hence for every mole hydrogen chloride produced, there is 1 mole of hydrogen and chlorine needed. When 1 mole each of the reactants are used, there is 72.9 grams of HCl produced. We multiply 2 with the molar mass of HCl.
Answer:
696g
Explanation:
To determine the mass of ethylbutanoate produced, it is important that we know the number of moles of ethylbutanoate produced.
Now from the chemical equation, it can be seen that one mole of ethanol produces one mole of ethylbutanoate. This means that 6.0 mol of ethanol will surely produce 6.0 mol of ethylbutanoate.
Now, we need to get the mass of ethylbutanoate produced. The mass of ethylbutanoate produced is the number of moles of ethylbutanoate produced multiplied by the molar mass of ethylbutanoate produced.
The molar mass of ethylbutanoate is 12(6) + 12(1) + 16(2) = 116g/mol
The mass thus produced is 116 * 6 = 696g
